Avoid creating help.sh and test.sh in cwd (#35123)
When running unit-test the test/ci.py module is leaving
garbage (help.sh, test.sh files) in the current working
directory.

This commit changes the current working directory to a
temporary path before those files are created.

environments: don't replace relative view path with absolute path on concretize/install (#34958)
* environments: don't rewrite relative view path, expand path on cli ahead of time

Currently if you have a spack.yaml that specifies a view by relative
path, Spack expands it to an absolute path on `spack -e . install` and
persists that to disk.

This is rather annoying when you have a `spack.yaml` file inside a git
repo, cause you want to use relative paths to make it relocatable, but
you constantly have to undo the changes made to spack.yaml by Spack.

So, as an alternative:

1. Always stick to paths as they are provided in spack.yaml, never
   replace them with a canonicalized version
2. Turn relative paths on the command line into absolute paths before
   storing to spack.yaml. This way you can do `spack env create --dir
   ./env --with-view ./view` and both `./env` and `./view` are resolved
   to the current working dir, as expected (not `./env/view`). This
   corresponds to the old behavior of `spack env create`.

* create --with-view always takes a value

Identify Windows support with tags (#35027)
All packages with explicit Windows support can be found with
`spack list --tags=windows`.

This also removes the documentation which explicitly lists
supported packages on Windows (which is currently out of date and
is now unnecessary with the added tags).

Note that if a package does not appear in this list, it *may*
still build on Windows, but it likely means that no explicit
attempt has been made to support it.

buildcache create: make "file exists" less verbose (#35019)

`--make-target-prefix` to it.

Bugfix: External Python Extensions (#34202)
Normally when using external packages in concretization, Spack ignores
all dependencies of the external. #33777 updated this logic to attach
a Python Spec to external Python extensions (most py-* packages), but
as implemented there were a couple issues:

* this did not account for concretization groups and could generate
  multiple different python specs for a single DAG
* in some cases this created a fake Python spec with insufficient
  details to be usable (concretization/installation of the
  extension would fail)

This PR addresses both of these issues: 

* For environment specs that are concretized together, external python
  extensions in those specs will all be assigned the same Python spec
* If Spack needs to "invent" a Python spec, then it will have all the
  needed details (e.g. compiler/architecture)

depfile: variable with all identifiers (#34678)
With the new variable [prefix/]SPACK_PACKAGE_IDS you can conveniently execute
things after each successful install.

For example push just-built packages to a buildcache

```
SPACK ?= spack
export SPACK_COLOR = always
MAKEFLAGS += -Orecurse
MY_BUILDCACHE := $(CURDIR)/cache

.PHONY: all clean

all: push

ifeq (,$(filter clean,$(MAKECMDGOALS)))
include env.mk
endif

# the relevant part: push has *all* example/push/<pkg identifier> as prereqs
push: $(addprefix example/push/,$(example/SPACK_PACKAGE_IDS))
	$(SPACK) -e . buildcache update-index --directory $(MY_BUILDCACHE)
	$(info Pushed everything, yay!)

# and each example/push/<pkg identifier> has the install target as prereq,
# and the body can use target local $(HASH) and $(SPEC) variables to do
# things, such as pushing to a build cache
example/push/%: example/install/%
	@mkdir -p $(dir $@)
	$(SPACK) -e . buildcache create --allow-root --only=package --unsigned --directory $(MY_BUILDCACHE) /$(HASH) # push $(SPEC)
	@touch $@

spack.lock: spack.yaml
	$(SPACK) -e . concretize -f

env.mk: spack.lock
	$(SPACK) -e . env depfile -o $@ --make-target-prefix example

clean:
	rm -rf spack.lock env.mk example/

Remove verbose warning message from _try_install_from_binary_cache (#34994)
In the past we checked remote binary mirrors for existence of a spec
before attempting to download it. That changed to only checking local
copies of index.jsons (if available) to prioritize certain mirrors where
we expect to find a tarball. That was faster for CI since fetching
index.json and loading it just to order mirrors takes more time than
just attempting to fetch tarballs -- and also if we have a direct hit
there's no point to look at other mirrors.

Long story short: the info message only makes sense in the old version
of Spack, so it's better to remove it.

Refer to mirrors by name, path, or url (#34891)
With this change we get the invariant that `mirror.fetch_url` and
`mirror.push_url` return valid URLs, even when the backing config
file is actually using (relative) paths with potentially `$spack` and
`$env` like variables.

Secondly it avoids expanding mirror path / URLs too early,
so if I say `spack mirror add name ./path`, it stays `./path` in my
config. When it's retrieved through MirrorCollection() we
exand it to say `file://<env dir>/path` if `./path` was set in an
environment scope.

Thirdly, the interface is simplified for the relevant buildcache
commands, so it's more like `git push`:

```
spack buildcache create [mirror] [specs...]
```

`mirror` is either a mirror name, a path, or a URL.

Resolving the relevant mirror goes as follows:
    
- If it contains either / or \ it is used as an anonymous mirror with
   path or url.
- Otherwise, it's interpreted as a named mirror, which must exist.

This helps to guard against typos, e.g. typing `my-mirror` when there
is no such named mirror now errors with:

```
$ spack -e . buildcache create my-mirror
==> Error: no mirror named "my-mirror". Did you mean ./my-mirror?
```

instead of creating a directory in the current working directory. I
think this is reasonable, as the alternative (requiring that a local dir
exists) feels a bit pendantic in the general case -- spack is happy to
create the build cache dir when needed, saving a `mkdir`.

The old (now deprecated) format will still be available in Spack 0.20,
but is scheduled to be removed in 0.21:

```
spack buildcache create (--directory | --mirror-url | --mirror-name) [specs...]
```

This PR also touches `tmp_scope` in tests, because it didn't really
work for me, since spack fixes the possible --scope values once and
for all across tests, so tests failed when run out of order.

config: make path replacements lazy (#34758)
Currently, all of the replacements in `spack.util.path.replacements()` get evaluated for
each replacement. This makes it easy to get bootstrap issues, because config is used
very early on in Spack.

Right now, if I run `test_autotools_gnuconfig_replacement_no_gnuconfig` on my M1 mac, I
get the circular reference error below. This fixes the issue by making all of the path
replacements lazy lambdas.

As a bonus, this cleans up the way we do substitution for `$env` -- it's consistent with
other substitutions now.

- [x] make all path `replacements()` lazy
- [x] clean up handling of `$env`

```console
> spack unit-test -k test_autotools_gnuconfig_replacement_no_gnuconfig

...

==> [2022-12-31-15:44:21.771459] Error: AttributeError:

The 'autotools-config-replacement' package cannot find an attribute while trying to build from sources. This might be due to a change in Spack's package format to support multiple build-systems for a single package.

FileCache: Delete the new cache file on exception (#34623)
The code in FileCache for write_transaction attempts to delete the temporary file when an exception occurs under the context by calling shutil.rmtree. However, rmtree only operates on directories while the rest of FileCache uses normal files. This causes an empty file to be written to the cache key when unneeded.

Use os.remove instead which operates on normal files.

Simplify creation of test and install reports (#34712)
The code in Spack to generate install and test reports currently suffers from unneeded complexity. For
instance, we have classes in Spack core packages, like `spack.reporters.CDash`, that need an
`argparse.Namespace` to be initialized and have "hard-coded" string literals on which they branch to
change their behavior:

```python
if do_fn.__name__ == "do_test" and skip_externals:
    package["result"] = "skipped"
else:
    package["result"] = "success"
package["stdout"] = fetch_log(pkg, do_fn, self.dir)
package["installed_from_binary_cache"] = pkg.installed_from_binary_cache
if do_fn.__name__ == "_install_task" and installed_already:
    return
```
This PR attempt to polish the major issues encountered in both `spack.report` and `spack.reporters`.

Details:
- [x] `spack.reporters` is now a package that contains both the base class `Reporter` and all 
      the derived classes (`JUnit` and `CDash`)
- [x] Classes derived from `spack.reporters.Reporter` don't take an `argparse.Namespace` anymore
       as argument to `__init__`. The rationale is that code for commands should be built upon Spack
       core classes, not vice-versa.
- [x] An `argparse.Action` has been coded to create the correct `Reporter` object based on command
       line arguments
- [x] The context managers to generate reports from either `spack install` or from `spack test` have
       been greatly simplified, and have been made less "dynamic" in nature. In particular, the `collect_info`
       class has been deleted in favor of two more specific context managers. This allows for a simpler
       structure of the code, and less knowledge required to client code (in particular on which method to patch)
- [x] The `InfoCollector` class has been turned into a simple hierarchy, so to avoid conditional statements
       within methods that assume a knowledge of the context in which the method is called.

bugfix: setgid tests fail when primary group is unknown (#34729)
On systems with remote groups, the primary user group may be remote and may not exist on
the local system (i.e., it might just be a number). On the CLI, it looks like this:

```console
> touch foo
> l foo
-rw-r--r-- 1 gamblin2 57095 0 Dec 29 22:24 foo
> chmod 2000 foo
chmod: changing permissions of 'foo': Operation not permitted
```

Here, the local machine doesn't know about per-user groups, so they appear as gids in
`ls` output. `57095` is also `gamblin2`'s uid, but the local machine doesn't know that
`gamblin2` is in the `57095` group.

Unfortunately, it seems that Python's `os.chmod()` just fails silently, setting
permissions to `0o0000` instead of `0o2000`. We can avoid this by ensuring that the file
has a group the user is known to be a member of.

- [x] Add `ensure_known_group()` in the permissions tests.
- [x] Call `ensure_known_group()` on tempfile in `test_chmod_real_entries_ignores_suid_sgid`.

docs: avoid errors by using type hints instead of doc types (#34707)
There are a number of places in our docstrings where we write "list of X" as the type, even though napoleon doesn't actually support this. It ends up causing warnings when generating docs.

Now that we require Python 3, we don't have to rely on type hints in docs -- we can just use Python type hints and omit the types of args and return values from docstrings.

We should probably do this for all types in docstrings eventually, but this PR focuses on the ones that generate warnings during doc builds.

Some `mypy` annoyances we should consider in the future:
1. Adding some of these type annotations gets you:
    ```
    note: By default the bodies of untyped functions are not checked, consider using --check-untyped-defs  [annotation-unchecked]
    ```
   because they are in unannotated functions (like constructors where we don't really need any annotations).
   You can silence these with `disable_error_code = "annotation-unchecked"` in `pyproject.toml`
2. Right now we support running `mypy` in Python `3.6`.  That means we have to support `mypy` `.971`, which does not support `disable_error_code = "annotation-unchecked"`, so I just filter `[annotation-unchecked]` lines out in `spack style`.
3. I would rather just turn on `check_untyped_defs` and get more `mypy` coverage everywhere, but that will require about 1,000 fixes.  We should probably do that eventually.
4. We could also consider only running `mypy` on newer python versions.  This is not easy to do while supporting `3.6`, because you have to use `if TYPE_CHECKING` for a lot of things to ensure that 3.6 still parses correctly.  If we only supported `3.7` and above we could use [`from __future__ import annotations`](https://mypy.readthedocs.io/en/stable/runtime_troubles.html#future-annotations-import-pep-563), but we have to support 3.6 for now. Sigh.

- [x] Convert a number of docstring types to Python type hints
- [x] Get rid of "list of" wherever it appears

Consolidate how Spack uses git (#34700)
Local `git` tests will fail with `fatal: transport 'file' not allowed` when using git 2.38.1 or higher, due to a fix for `CVE-2022-39253`.

This was fixed in CI in #33429, but that doesn't help the issue for anyone's local environment. Instead of fixing this with git config in CI, we should ensure that the tests run anywhere.

- [x] Introduce `spack.util.git`.
- [x] Use `spack.util.git.get_git()` to get a git executable, instead of `which("git")` everywhere.
- [x] Make all `git` tests use a `git` fixture that goes through `spack.util.git.get_git()`.
- [x] Add `-c protocol.file.allow=always` to all `git` invocations under `pytest`.
- [x] Revert changes from #33429, which are no longer needed.
