Looking at the memory profiles of concurrent solves
for environment with unify:false, it seems memory
is only ramping up.
This exchange in the potassco mailing list:
https://sourceforge.net/p/potassco/mailman/potassco-users/thread/b55b5b8c2e8945409abb3fa3c935c27e%40lohn.at/#msg36517698
Seems to suggest that clingo doesn't release memory
until end of the application.
Since when unify:false we distribute work to processes,
here we give a maxtaskperchild=1, so we clean memory
after each solve.
Some providers must provide virtuals "together", i.e.
if they provide one virtual of a set, they must be the
providers also of the others.
There was a bug though, where we were not checking if
the other virtuals in the set were needed at all in
the DAG.
This commit fixes the bug.
* libtheora: regenerate Makefile.in during autoreconf
The patch to inhibit running of configure would exit autogen.sh so early
that it did not yet run autoconf/automake/...
Instead of patching autogen.sh, just pass -V as argument, as this is
passed on to configure and lets it just print its version instead of
configuring the build tree.
Also drop arguments from autogen.sh, as they are unused when configure
does not run.
* libtheora: fix build on macos
Apply upstream patches in order to avoid unresolved symbols during building of libtheoraenc.
These patches require re-running automake/autoconf/...

stable as version name for theora-1.1 branch was chosen so that it sorts between 1.1.x and master
* libtheora: remove unused patch
thanks to @michaelkuhn for noticing
* Add 2023.09-0 for x86_64, aarch64, and ppc64le
extend the anaconda3 package.py to support aarch64 and ppc64le.
add the latest version of anaconda3 to each new platform, including the existing x86_64
* formatting
* Fix py-pyside2 to build with newer llvm and to use spack libglx and libxcb headers where system headers are missing
pyside2 needs LLVM_INSTALL_DIR to be set when using llvm 11: and expects system headers for libglx and libxcb and won't build otherwise.
* Fix styling
* remove raw string type
* Update var/spack/repos/builtin/packages/py-pyside2/package.py

This PR makes it possible to select only a subset of virtual dependencies from a spec that _may_ provide more. To select providers, a syntax to specify edge attributes is introduced:
```
hdf5 ^[virtuals=mpi] mpich
```
With that syntax we can concretize specs like:
```console
$ spack spec strumpack ^[virtuals=mpi] intel-parallel-studio+mkl ^[virtuals=lapack] openblas
```
On `develop` this would currently fail with:
```console
$ spack spec strumpack ^intel-parallel-studio+mkl ^openblas
==> Error: Spec cannot include multiple providers for virtual 'blas'
Requested 'intel-parallel-studio' and 'openblas'
```
In package recipes, virtual specs that are declared in the same `provides` directive need to be provided _together_. This means that e.g. `openblas`, which has:
```python
provides("blas", "lapack")
```
needs to provide both `lapack` and `blas` when requested to provide at least one of them.
## Additional notes
This capability is needed to model compilers. Assuming that languages are treated like virtual dependencies, we might want e.g. to use LLVM to compile C/C++ and Gnu GCC to compile Fortran. This can be accomplished by the following[^1]:
```
hdf5 ^[virtuals=c,cxx] llvm ^[virtuals=fortran] gcc
```
[^1]: We plan to add some syntactic sugar around this syntax, and reuse the `%` sigil to avoid having a lot of boilerplate around compilers.
Modifications:
- [x] Add syntax to interact with edge attributes from spec literals
- [x] Add concretization logic to be able to cherry-pick virtual dependencies
- [x] Extend semantic of the `provides` directive to express when virtuals need to be provided together
- [x] Add unit-tests and documentation
* vcftools: adding new version 0.1.16
* Update var/spack/repos/builtin/packages/vcftools/package.py
