- Add a test that verifies checksums on all packages
- Also add an attribute to packages that indicates whether they need a
manual download or not, and add an exception in the tests for these
packages until we can verify them.

- `spack.util.environment` is the new home for routines that modify
environment variables.
- This is to make room for `spack.environment` to contain new routines
for dealing with spack environments
- 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
Replace use of `shutil.copytree` with `copy_tree` and `install_tree` functions in `llnl.util.filesystem`.
- `copy_tree` copies without setting permissions. It should be used to copy files around in the build directory.
- `install_tree` copies files and sets permissions. It should be used to copy files into the installation directory.
- `install` and `copy` are analogous single-file functions.
- add more extensive tests for these functions
- update packages to use these functions.
