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
* Add latest libyogrt versions
* Add url_for_version to handle differing url formats for different
versions
* Add 'scheduler' variant to configure scheduler. Currently only
slurm can be installed with Spack. A value of 'system' indicates
to use the scheduler installed on the system
- 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
* SCR CMake package
* Fix dtcmp variant description and set pdsh deptypes to build/run
* added variants for system config file location
* add variants for several scr cmake options
* Added more variants for compile time options
* Added libyogrt and made corrosponding changes to scr package.
* Cleanup yogrt package now that Ive verified it works
* Added description for libyogrt
* upper case async api names
* Make use of mv variants
* fix pdsh package for scr
* added IBM BBAPI as async option
* update pdsh and scr to use static pdsh modules
