* Update go to 1.7.4 and 1.6.4 to fix security issues
The go team recently rolled out two releases to address security
issues. Details available on the [go release
site](https://golang.org/doc/devel/release.html).
This commit updates our explicitly supported versions.
It also includes a comment about two CentOS requirements (enable
user_namespace and ensure that the static c library is installed) that
are required for the pacakges to pass their tests.
* Flake8 cleanup
* Added some notes about how multiarch detection could be fixed.
* Implemented a preliminary version of the "spack.spec.ArchSpec" class.
* Updated the "spack.spec.Spec" class to use "ArchSpec" instead of "Arch".
* Fixed a number of small bugs in the "spack.spec.ArchSpec" class.
* Fixed the 'Concretizer.concretize_architecture' method so that it uses the new architecture specs.
* Updated the package class to properly use arch specs.
Removed a number of unused architecture functions.
* Fixed up a number of bugs that were causing the regression tests to fail.
Added a couple of additional regression tests related to architecture parsing/specification.
Fixed a few bugs with setting reserved os/target values on "ArchSpec" objects.
Removed a number of unnecessary functions in the "spack.architecture" and "spack.concretize" modules.
* Fixed a few bugs with reading architecture information from specs.
Updated the tests to use a uniform architecture to improve reliability.
Fixed a few minor style issues.
* Adapted the compiler component of Spack to use arch specs.
* Implemented more test cases for the extended architecture spec features.
Improved error detection for multiple arch components in a spec.
* Fix for backwards compatibility with v0.8 and prior
* Changed os to unknown for compatibility specs
* Use `spack09` instead of `spackcompat` for the platform of old specs.
* Make X11 font install dir the font search default
We install the X11 fonts into `/share/fonts` beneath the font-util
installation prefix, but that directory is not one of the places that
the font subsystem searches.
This commit makes the fontconfig package depend on the font-util
package, and then it makes
```python
spec['font-util'].prefix + "/share/fonts"
```
be the fontconfig default font location.
Before this change, plots drawn by R have bounding boxes where font
glyphs should be. After this change fonts appear as expected.
* Enrich description string (trigger new CI run)
Improve the docstring for the package.
Also interested in the side effect of triggering another CI run
to see if the recent flake8 fix lets this PR run clean.
* Flake8 cleanups
* Update R&friends to use our X11 libs
Add `depends_on()`'s for R, Cairo, and Tk so that they use the Spack X
bits.
* Conditionalize X stuff on variant
Another step towards hooking up the X stuff.
There's still discussion happening on the issue, but this is better
than the 'everything must build with X' state that it was in.
- Added 'dap' and 'cdmremote' variants
This is based on work in #2324 with the following motivation:
Turn off DAP support by deafult. DAP requires curl, which has issues
with circular dependencies. For 95% of NetCDF users that do not need
DAP, turning it off avoides this rats nest of problems.
- Added 'parallel-netcdf' variant
To support work with parallel-netcdf
- Added 'shared' and 'static' build separation
* Update go-bootstrap package
The last C based Go src tree was the 1.4 series. For a while they
were cutting new releases so that people could bootstrap from a C only
system. Now they're recommending that you either use the release-1.4
branch or that you use a date-stamped tarball that they'll produce on
an as-needed basis.
There are several issues that keep 1.4.2 from building on a CentOS 7
system.
I've switched to the date based tarball.
The cgo bits were also mis-behaving, but they're not needed for the
bootstrapping task so I've set an environment variable that disables
them.

page](https://golang.org/doc/install/source#go14) and these issues:

- https://github.com/golang/go/issues/16352.
* Update go package
Switched from pulling from the git repository to using the source
tarballs and added digest values.
Added support for 1.7.3, continued supporting 1.6.2, including patches
for a couple of problems (details in
[17545](https://github.com/golang/go/issues/17545) and
[17986](https://github.com/golang/go/issues/17986).
Dropped support for 1.5.4 and 1.4.2 because they no longer pass their
tests and the patches above to not apply.
Different compilers have different flags for PIC (position-independent
code). This patch provides a common ground to accessing it inside specs.
See discussions in #508 and #2373. This patch does not address the issue
of mixed compilers as mentioned in #508.
