According to my nightly CI/CD tests, x.org is another large provider
of software in common build chains that is often down.
Added a hand-selected amount of mirrors that is well up-to-sync.
Tested with `util-macros` that has a quite "recent" patch release.

* Patch Mathematica
Mathematica installer moves all files and directories from installation directory to a backup one. The problem is that it also moves .spack to this backup location. Once it's done it does not move .spack back where it was.
My patch creates a copy of .spack to /tmp then moves it back right before exiting the install call.
* Make lint happy
* Use Spack native copy()
As suggested in peer-review let's:
- Copy .spack to stage directory so I don't have to use random
- Use Spack native copy() to do these operations
* Use join_path to create paths
As per peer-review suggestion:
- Use join_path to create paths

* new package: BART
This PR adds the BART (Berkeley Advanced Reconstruction Toolset)
package.
Despite the presence of CMake files, this package builds with a
Makefile. It looks like the project is moving away from cmake. The patch
for MKL has been committed upstream so should only be necessary for this
version of BART. The Makefile patch is meant for working with Spack and
would not be useful upstream. The bart scripts are still setup to use
bart with the subcommands being individual binaries. This patches those
to use the single binary with built-in subcommands and assumes that
spack is providing the TOOLBOX environment variable and setting PATH.

* new package: py-youtube-dl + fixes for dependencies
This PR adds the py-youtube-dl program. In addition, there are a couple
of dependency packages that needed to be updated.
* ffmpeg
This is needed by py-youtube-dl. However, the spack ffmpeg recipe does
not include a lot of options, specifically, a dependency on openssl for
working with the https protocol.
- Added updated version.
- Added variants for the different licensing options.
- Added "meta" variants for X and drawtext. These turn on/off several
options.
- Set variants and dependencies for many options. The defaults are based
on the configuration settings in ffmpeg.
- Set dependencies that were missing or that will likely get pulled in
from the system.
* libxml2
The ffmpeg+libxml2 variant initially failed to build. The issue is that
libxml2 sets the headers property to
include_dir = self.spec.prefix.include.libxml2
The ffmpeg configure looks for prefix.include and fills in the rest.
This could probably be patched in ffmpeg but the headers property in the
libxml2 recipe is not consistent with the environment module or the
pkgconfig file, both of which set the headers path to prefix.include.
This PR sets the libxml2 headers property to
include_dir = self.spec.prefix.include
A spot check of a few libxml2 dependents did not rreveal any problems
with this change.
* Comment out libxml2 dependency in ffmpeg
The header property issue of the spack libxml2 package will need to be
resolved in another PR before libxml2 can be enabled in ffmpeg.
* new package: openmm

This adds a boolean 'libtirpc' variant to the hdf package.
Default is false, which will reproduce previous behavior (which
was to rely either on system xdr headers/library, or have hdf use
it's builtin xdr lib/headers (which are only for 32 bit))
If true, a dependency is added on 'libtirpc', and the LIBS and
CPPFLAGS are updated in the configure command to find the libtirpc
library and xdr.h header.
This is needed as RHEL8 (and presumably other distros have or will be)
removed xdr.h from glib-headers package,which was breaking the previous
behavior of using system xdr headers.
* opencv: assorted fixes
1. depends on blas when +lapack
2. set cuda nvcc flags for cuda_arch
3. let cuda/contrib builds work
4. depends on hdf5 when cuda/contrib
5. depends on ant when +java
6. allow protobuf version to be different
7. let opencv recompile it's protoc files.
* ant is a build-time dependency
* register +cuda~contrib as impossible.
The old api is found in version 0.3.0 which uses a different release
name, so the url function was updated to properly find the older
releases. Also, this removes the boost constraint on the 0.3.0 version
which does not need it.
* meson: Add 0.54.0
This change also improves the rpath patch we are using. Instead of never
removing the rpath, we now only keep it if running within Spack to
guarantee consistent behavior of Meson.
* meson: Make ninja a hard dependency
* Update doxygen package
* Add new version releases 1.8.16 and 1.8.17
* Add mscgen as an optional dependency.
* Update doxygen package.py
Fix typo in mscgen dependency specification
* Remove whitespace for flake8
* primer3: move to github, add 2.5.0, fix 2.3.7
- The Primer3 project moved to GitHub.
- update the URL
- compare the tarballs 2.3.7 from Sourceforge and github, no
significant differences (e.g. the Sourceforge tarball contained a
couple of "tmp" files).
- update the signature for the 2.3.7 tarball.
- @2.3.7 doesn't build with gcc@8.4.0, there's a dubious pointer/int
comparison that causes an error. It was fixed upstream in newer
versions, apply simple patch to this version so that it continues to
be build-able with newer compilers. See:
- https://github.com/primer3-org/primer3/issues/2
- https://github.com/primer3-org/primer3/issues/3
- Add info for @2.5.0, which builds cleanly.

Newer versions of glib require Meson, so this PR adds support for that
using a hybrid approach. glib@5.28: will be built using Meson, older
versions still make use of Autotools.
The most recent change to the openjdk package set expand=False for all versions
of the package. This means only the unexpanded archive will be installed, which is not correct.

Add new version 4.5.0 and update quarantine variable list to also

- Add info for version 0.68.3

* This was a regression that occured in previous PR. Flang has been excised from LLVM for now until f18 is merged upstream.
* Libraries only needed when a GPU backend is present.
* Add version 18-08-9-1
* Add variant to allow setting the sysconfdir: See below
About sysconfdir:
slurm has a server and a client.
To use the correct communication channel, the client needs
to be able to read the correct config. This config is in
PREFIX/etc.
Let's assume one has the server part installed as a system
package. This generally is a good idea, so that the server
gets started during boot. This means, that the config is
in /etc/slurm.
If one now wants to use the client part (library!) via
spack, one has a problem: spack's slurm looks in
SPACK-PACKAGE-PREFIX/etc for the config.
There needs to be a way to let the spack installed package
use the system's config.
So add a variant to override the path during build:
sysconfdir=/etc/slurm.
This is much like what happened in #15307 for munge.

* NETCDF: Remove maxdims maxvars variant
I'm not sure of the correct protocol to do this, so decided to make a stab and hopefully it works or I'm told the correct way...
The `maxdims` and `maxvars` variants for the NetCDF package were, to the best of my knowledge, only ever used for the Exodus library in the SEACAS package. In versions of NetCDF prior to 4.4.0, Exodus required that the `NC_MAX_DIMS` and `NC_MAX_VARS` be increased over the default values. This requirement was removed in 4.4.0 and later.
I do not know of any way to make a variant depend on the version and since the `maxdims` and `maxvars` variants are integer values and not boolean, then every build of NetCDF will have these variants. Typically `maxdims=1024 maxvars=8192` and the build will patch the `netcdf.h` include file for every build even though it is (almost) never needed.
The SEACAS package has a NetCDF version requirement of >4.6.2, so it no longer specifies the `maxdims` or `maxvars` variant and I could find no other package in spack that uses this variant either, so removal should not break anything *in* spack. However, there is no guarantee that some other external package doesn't use the variant, so I'm not sure of the correct way to remove the variant.
For this PR, I simply removed the variants. If there is a way to specify use of the variant tied to a specific version, I couldn't find it anywhere...

## Summary
This PR updates and improves the Spack package for [UPC++](https://upcxx.lbl.gov).
I'm an LBL employee and developer on the UPC++ team, as well as the maintainer of this Spack package.
### Key Improvements:
* Adding new 2020.3.0 release and support for use of develop/master branches
- Our build infrastructure underwent a major change in this release, switching from a hand-rolled Python2 script to a bash-based autoconf work-alike.
- The new build system is NOT using autotools (nor does it support some of the more esoteric autoconf options), but the user interface for common builds is similar.
* Add explicit support for an MPI optional dependency
- New `mpi` variant enables use of the MPI-based spawner (most relevant on loosely coupled clusters), and the (unofficial) mpi-conduit backend
- This variant is OFF by default, since UPC++ works fine without MPI on many systems, increasing the likelihood first-time Spack users get a working build without needing to correctly setup MPI
* Add support for post-install testing using the test support deployed in the new build infrastructure
* Fix or workaround a few bugs observed during testing
### Status
The new package has been validated with a variety of specs across over seven different systems, including: NERSC cori, ALCF Theta, OLCF Summit, an in-house Linux cluster, and macOS laptops (Mojave and Catalina).
Expose serial/parallel build (MPI), CUDA/OpenMP backends, Clang, and
Ascent bindings.
Interestingly, `warpx +ascent` currently leads to an infinite loop in
the Spack concretizer.
Git-based conditions database for HEP and other experiments.
Use latest release version and current master to support Linux and
macOS. Add core known dependencies and conflicts related to C++17
support.
cxxstd variant added to help transitive dependencies, and for future
support for newer standards in future.
