Added a wrapperrpath variant to mpich that defaults to `True`.
Users can set this to `False` (e.g., spack install mpich~wrapperrpath) to
disable the wrapper RPATHs. This makes it easier to replacing an MPICH
installation in a container with an MPICH for the host system,
e.g., Cray MPICH with Shifter on Cori, Intel MPI, MVAPICH2, etc.

- Trying to reduce the number of top-level files in Spack.
- CODE_OF_CONDUCT.md can be referenced from the README.
- CONTRIBUTING.md is only used to display a message on pull requests, and
it still does that when in .github.
The version of LLVM used by flang is new enough that CppBackend doesn't exist. Unfortunately, `flang-xxxxxxxx` is seen as < `3.9.0` by the version check.
* add a special case for `flang` versions.
- We've seen this a few times now where users have set up `cd` to echo
the new directory, and it screws up `setup-env.sh`
- In the past we've said this is user error.
- Here, we just fix it by sending `cd` output to /dev/null where needed.
- this works in bash, zsh, and dash
Add an example of a 'modules:' entry for an external package in
packages.yaml. The 'External Packages' section of 'Build
Customization' mentions 'paths:' and 'modules:' and gives an
example of paths, but not modules.
* OpenFOAM: rationalize architecture options
- older versions of OpenFOAM had WM_ARCH_OPTION to choose a 32-bit
build on 64-bit architectures. This is not exactly relevant anymore
and has now been largely removed from OpenFOAM.
- simultaneously the newest version of OpenFOAM has rationalized the
handling of special settings for KNL by rolling these into the
compiler options. We now do the same thing here in spack.
1. Reuse the internal variable arch_option to convey processor-specific
optimizations and add these into the C++OPT=... statement.
2. Drop spack support for configuring a 32-bit build on 64-bit
hardware.
These changes can also be applied to older OpenFOAM versions, and to
various OpenFOAM forks without issue.
* update openfoam versions. New release 1906, patched 1812 version.
ncl does not build with newer versions of gdal (or rather proj). This
also needs a small change to gdal, otherwise we end up with both proj@5
and proj@6 in the spec.
