Enable explicitly building glib with or without libiconv.

Heads up: if you build with ~iconv but there is something else in the
spec that includes libiconv then glib will *still* automagically
discover it and the build will fail.

 - fixed an issue where some undesirable parts of
   the spack source tree were being copied into
   the image context.

 - added a workaround for a tty ioctl warning on
   ubuntu

 - adjusted how the main images are built so that
   `RUN spack ...` works automatically for child
   images that base themselves on them.

* Record build output as an array of lines rather than concatenating to a
  single large string.
* Use string.find to avoid running re.search on every line of output.

When using the CDash reporter, upload a Update.xml file that
indicates the hash of Spack's current git commit.

Pass extra data when submitting to CDash.  If CDash responds with a buildId,
construct and display helpful URL that links to the uploaded report.

Add new command line arguments to `spack install` that allow users
to set the build name, site name, and track in their CDash report.

Make sure cdash_phase is defined before referring to it.

* CGNS: Allow use of git branch versions

Add ability to use git `master` and `develop` branches of the CGNS library.  The `seacas` package sometimes needs to use the `master` or `develop` branch due to some new changes to the parallel I/O implementation in CGNS which has not yet been released.

* CGNS: Reorder to put newest version on top

Based on review comments, place newest version (develop) first in list.

- some commands were missed in the rollout of spack environments

- this makes all commands that need to disambiguate specs restrict the
  disambiguation to installed packages in the active environment, as
  users would expect

* dyninst: patch to build dyninst with older gcc

Add 'v9.3.2-auto.patch'.  This patch changes some 'auto t: type' usage
to the older but equivalent 'type.begin()'.  This allows building
dyninst 9.3.2 with gcc 4.4 which doesn't support the newer syntax.
This patch is harmless with newer gcc.

* Fix typo in patch.  (My bad for sloppy cut-and-paste.)

* Restrict the patch to gcc 4.7 and earlier.  gcc 4.8 supports the newer
usage and thus doesn't need the patch.

Currently, only the Git repsository's URL shows up in the `spack info`
output, which makes it hard to distinguish different versions:
```
Safe versions:
    develop    [git] https://github.com/LLNL/H5Z-ZFP.git
    0.8.0      [git] https://github.com/LLNL/H5Z-ZFP.git
    0.7.0      [git] https://github.com/LLNL/H5Z-ZFP.git
```

This change adds additional information as shown when cloning a Git
repository:
```
Safe versions:
    develop    [git] https://github.com/LLNL/H5Z-ZFP.git on branch master
    0.8.0      [git] https://github.com/LLNL/H5Z-ZFP.git at commit af165c4
    0.7.0      [git] https://github.com/LLNL/H5Z-ZFP.git at commit 58ac811
```

* Updated Dakota to 6.9

* Change comment wording

* Add additional info to MesonPackage docs

* No Pygments lexer for Meson code, default to none
