* Libtool: add spack external find support
* Less specific regex
* match -> search
* Clarify that min returns first alphabetically, not shortest
* Simplify version determination
Users can now list mirrors of the main url in packages.
- [x] Instead of just a single `url` attribute, users can provide a list (`urls`) in the package, and these will be tried by in order by the fetch strategy.
- [x] To handle one of the most common mirror cases, define a `GNUMirrorPackage` mixin to handle all the standard GNU mirrors. GNU packages can set `gnu_mirror_path` to define the path within a mirror, and the mixin handles setting up all the requisite GNU mirror URLs.
- [x] update all GNU packages in `builtin` to use the `GNUMirrorPackage` mixin.
We'd like to use a consistent checksum scheme everywhere so that we can:
a) incorporate archive checksums into our specs and have a
consistent hashing algorithm across all specs.
b) index mirrors with a consistent type of checksum, and not one that
is dependent on how spack packages are written.
- [x] convert existing md5, sha224, sha512, sha1 checksums to sha256
- remove the old LGPL license headers from all files in Spack
- add SPDX headers to all files
- core and most packages are (Apache-2.0 OR MIT)
- a very small number of remaining packages are LGPL-2.1-only
To accommodate build systems on Darwin which look for glibtool/ize,
#7060 attempted to provide glibtool/ize symlinks for libtool/ize
but accidentally created the same symlink twice. #7073 reverted this
and replaced libtool/ize with glibtool/ize on Darwin. This led to
#7163 since AutotoolsPackages depend on the presence of the 'libtool'
binary, so this returns to the approach of #7160 but makes the
correct symlinks.
* libtool: fix linking of libtool on darwin
* binutils, libtool: fix conflicts w/ BSD tools, v2
Fix namespace conflicts with BSD tools in a more elegant fashion,
using a program prefix, similar to Homebrew.
On Darwin and other BSD systems, the system 'libtool' and 'libtoolize'
are BSD libtool and libtoolize, respectively. Some build systems
require the GNU versions of these commands, so BSD package systems
tend to name the GNU versions 'glibtool' and 'glibtoolize',
respectively, to avoid namespace collisions.
A problem with the current libtool package is that it installs the GNU
libtool commands as 'libtool' and 'libtoolize', respectively, but
build systems on BSD platforms will attempt to run 'glibtool' and
'glibtoolize'. The expedient solution to this problem is to symlink
'libtool' to 'glibtool' and 'libtoolize' to 'glibtoolize', because
attempting to patch the detection logic one build system at a time
seems impractical.
* AutotoolsPackage: added configure_directory to permit build out of source. The configure script executable is now invoked with an absolute path. Modified a few packages accordingly.
* build_systems: functions returning directories are now properties
* build_systems: fixed issues with tcl and tk
* AutotoolsPackage: reworked recipe for autoreconf
- This moves var/spack/packages to var/spack/repos/builtin/packages.
- Packages that did not exist in the source branch, or were changed in
develop, were moved into var/spack/repos/builtin/packages as part of
the integration.

Package repositories now look like this:
top-level-dir/
repo.yaml
packages/
libelf/
package.py
mpich/
package.py
...
This leaves room at the top level for additional metadata, source,
per-repo configs, indexes, etc., and it makes it easy to see that
something is a spack repo (just look for repo.yaml and packages).
