* ADIOS2: Version `master`

Rename branch version to supported, real development branch `master`.
The old name is legacy Spack when alternative development branch
names were not yet supported.

* ADIOS: Simplify via spec Variable

use the already defined local variable `spec` to shorten
lines

Add the python dependency and CMake hints when build with tests.
`spack install --tests=root adios2`

This recovers the old behavior of replace_prefix_bin that was
modified to work with elf binaries by prefixing os.sep to new prefix
until length is the same as old prefix.

Since 1.9.0 is broken for Darwin, which impacts many developers, and
the fix is still a RC, let's keep the previous release as default.

This avoids distruption for OSX developers and CI.

Removed the code that was converting the old index.yaml format into
index.json. Since the change happened in #2189 it should be
considered safe to drop this (untested) code.

* use os.sep instead of null byte to pad replacement paths in binaries

* Prefix the pading os.sep's

fixes #15184

GraphBLAS depends on m4 according to CMake error message
Do not use INSTALL= when compiling the library

Spack's fflags are meant for both f77 and fc. Therefore, they must
be passed as FFLAGS and FCFLAGS to the configure scripts of
Autotools-based packages.

* added UQTk package

* Add missing expat dependency to uqtk

Increase the connect timeout for elfutils to 60 sec.  Elfutils (and
bzip2) tar files are on sourceware.org which is often slow to respond.

and found when using the RelWithDebInfo build type.  Change protobuf
to only support Release and Debug build types.

cherry-picking global ordinal type variant from https://github.com/spack/spack/pull/14215

 and setting dealii to GO int, to make it compile again (#15288)

* @develop needs the full git repo to use "git describe"
  properly

* If not specifying the cxxstd variant, let cmake use its
  default

* Improve fmt dependencies: fairlogger < 1.6.2 does not
  work with fmt >= 6.

* Small other stuff

* Created stub

* added description and homepage

* added dependencies

* removed extra boilerplae

* switched to the pkgconfig provider

Suite-sparse 5.7.0 and 5.7.1 need separate make and make install run to be able to compile, too

Just `depend_on('ncurses')`, pkgconfig seems to cause the right thing
to happen if the package is built +termlib or ~termlib (tested both
ways on a CentOS 7 system).

Additional details in: https://github.com/spack/spack/issues/15281

Tested by building all of the releases of tmux on a CentOS 7 box.

"container" is partly a misnomer, as it's realy
the extended allocators part of container.

But every part calls it container, so we do too.

The distributed build PR (#13100) -- did not check the install status of dependencies when using the `--only package` option so would refuse to install a package with the claim that it had uninstalled dependencies whether that was the case or not.

- [x] add install status checks for the `--only package` case.
- [x] add initial set of tests

[OpenBLAS 0.3.9](https://github.com/xianyi/OpenBLAS/releases/tag/v0.3.9) was released.

* add preliminary afqmc support in qmcpack

* afqmc updates

* fix spack typos

* edit AFQMC to only allow up 3.7 or above

* added NCCL library support for AFQMC build

* add CMAKE args for BUILD_AFQMC_WITH_NCCL

* update for just AFQMC support. No AFQMC+GPU support

* remove nccl for afqmc

* flake8 whitespace fix

* Update flag_handler for 'netcdf-fortran'.

* Refactoring.

* Enable old versions of netcdf-fortran for NAG.

* Disable parallel 'make check' for versions before 4.5.0.

* Fix shared libraries built with NAG instead of conflicting it.

* Add 'skosukhin' as a maintainer of 'netcdf-fortran'.

This PR adds some fixes for the tcsh package.

- Adds new version
- adds list_url so fetching works for current and old tarballs
- sets ncurses dependency explicitly to `ncurses+termlib`

If `+termlib` is not set then it will link against the system libtinfo.

* Quantum-Espresso: qe-6.5 fails to detect MKL for FFT

qe-6.5 fails to detect MKL for FFT if BLAS_LIBS is set due to
an unfortunate upsteam change in their autoconf/configure:
- qe-6.5/install/m4/x_ac_qe_blas.m4 only sets 'have_blas'
  but no 'have_mkl' if BLAS_LIBS is set (which seems to be o.k.)
- however, qe-6.5/install/m4/x_ac_qe_fft.m4 in 6.5 unfortunately
  relies on x_ac_qe_blas.m4 to detect MKL and set 'have_mkl'
- qe-5.4 up to 6.4.1 had a different logic and worked fine with
  BLAS_LIBS being set
However, MKL is correctly picked up by qe-6.5 for BLAS and FFT if
MKLROOT is set (which SPACK does automatically for ^intel-mkl).
Thus, do not set BLAS_LIBS when compiling qe-6.5 with intel-mkl.

* replace all '^intel-mkl' by '^mkl' to match other packages which also provide MKL

e.g. intel-parallel-studio+mkl as mentioned by @adamjstewart in #15276

* Filter problematic flag from std_cmake_args

Including '-DCMAKE_VERBOSE_MAKEFILE:BOOL=ON' in the cmake args causes
bits of cmake's output to end up in the autoconf-generated configure
script.  See https://github.com/spack/spack/issues/15274 and

* Don't build in parallel (sigh)

* Constrain hackery for newer versions...

... to newer versions.

* fix typos

* minor improvement

* add version 3.4.15
