* mumps: Add support for Intel compiler and insure both lapack and blas libraries are passed to the examples
Likely it was not discoverged before that the examples require both lapack and blas libraries because it
was tested with Openblas which is one large library containing everything.

* flake8 fix.
* Turned <provider>_libs into an iterable
Modifications :
- added class LibraryList + unit tests
- added convenience functions `find_libraries` and `dedupe`
- modifed non Intel blas/lapack providers
- modified packages using blas_shared_libs and similar functions
* atlas : added pthread variant
* intel packages : added lapack_libs and blas_libs
* find_library_path : removed unused function
* PR review : fixed last issues
* LibraryList : added test on __add__ return type
* LibraryList : added __radd__ fixed unit tests
fix : failing unit tests due to missing `self`
* cp2k and dependecies : fixed blas-lapack related statements in package.py
Add version 4.0.3 to metis package. Attempted to implement reasonable
versions of all variants declared for metis@5.1.0; some of these do
not have analogues in metis@4.0.3, and errors are raised accordingly.
Also updated dependencies of packages with depends_on('metis') to
depends_on('metis@5:') to ensure that these packages still build.
Prior to this commit, spack installs a library called `libmpiseq` into
`spec['mumps'].prefix.lib` when it builds MUMPS without MPI. However, it
does not also install the headers corresponding to this library, so it
is impossible to compile source files that depend on function calls
implemented in this library. This commit fixes this problem by
installing these headers, which are needed by packages (e.g., IPOPT)
that depend on these headers.
