Rename the `spack diy` command to `spack dev-build` to make the use case clearer.
The `spack diy` command has some useful functionality for developers using Spack to build their dependencies and configure/build/install the code they are developing. Developers do not notice it, partly because of the obscure name.
The `spack dev-build` command has a `-u/--until PHASE` option to stop after a given phase of the build. This can be used to configure your project, run cmake on your project, or similarly stop after any stage of the build the user wants. These options are analogous to the existing `spack configure` and `spack build` commands, but for developer builds.
To unify the syntax, we have deprecated the `spack configure` and `spack build` commands, and added a `-u/--until PHASE` option to the `spack install` command as well.
The functionality in `spack dev-build` (specifically `spack dev-build -u cmake`) may be able to supersede the `spack setup` command, but this PR does not deprecate that command as that will require slightly more thought.

sure we pick the right command.

It seems that 3.4.2 includes a change that is supposed to fix parallel
builds (https://lists.gnu.org/archive/html/bug-bison/2019-08/msg00000.html).
Instead, it actually breaks it for me (with -j48) with errors such as:
```
mv: cannot stat 'examples/c/reccalc/scan.stamp.tmp': No such file or directory
Makefile:9323: recipe for target 'examples/c/reccalc/scan.stamp' failed
```

This PR ensures that environment activation sets all environment variables set by the equivalent `module load` operations, except that the spec prefixes are "rebased" to the view associated with the environment.
Currently, Spack blindly adds paths relative to the environment view root to the user environment on activation. Issue #12731 points out ways in which this behavior is insufficient.
This PR changes that behavior to use the `setup_run_environment` logic for each package to augment the prefix inspections (as in Spack's modulefile generation logic) to ensure that all necessary variables are set to make use of the packages in the environment.
See #12731 for details on the previous problems in behavior.
This PR also updates the `ViewDescriptor` object in `spack.environment` to have a `__contains__` method. This allows for checks like `if spec in self.default_view`. The `__contains__` operator for `ViewDescriptor` objects checks whether the spec satisfies the filters of the View descriptor, not whether the spec is already linked into the underlying `FilesystemView` object.
Boost iostream autodetects the compression libraries libzstd and
liblzma outside of the Spack environment.
This commit disables mentioned libraries. In the future if the
Spack zstd/lzma packages were added as dependencies of the Spack
Boost package, additional work could be done to build Boost with
the Spack-built versions of these libraries.
