* Add version 18-08-9-1
* Add variant to allow setting the sysconfdir: See below

About sysconfdir:

slurm has a server and a client.
To use the correct communication channel, the client needs
to be able to read the correct config.  This config is in
PREFIX/etc.

Let's assume one has the server part installed as a system
package.  This generally is a good idea, so that the server
gets started during boot.  This means, that the config is
in /etc/slurm.

If one now wants to use the client part (library!) via
spack, one has a problem: spack's slurm looks in
SPACK-PACKAGE-PREFIX/etc for the config.

There needs to be a way to let the spack installed package
use the system's config.

So add a variant to override the path during build:
sysconfdir=/etc/slurm.

This is much like what happened in #15307 for munge.

If a user invoked "spack env activate example-henv", Spack would
mistakenly interpret the "-h" from "example-henv" as the "-h" option.
This commit allows users to create and activate environments with
"-h" in the name.

This issue existed for bash shell support as well as csh support, and
this commit addresses both, along with some other unrelated csh
support issues.

Currently, to force Spack to use an external MPI, you have to specify `buildable: False`
for every MPI provider in Spack in your packages.yaml file. This is both tedious and
fragile, as new MPI providers can be added and break your workflow when you do a
git pull.

This PR allows you to specify an entire virtual dependency as non-buildable, and
specify particular implementations to be built:

```
packages:
all:
    providers:
        mpi: [mpich]
mpi:
    buildable: false
    paths:
        mpich@3.2 %gcc@7.3.0: /usr/packages/mpich-3.2-gcc-7.3.0
```
will force all Spack builds to use the specified `mpich` install.

* geant4: new version 10.6 plus simplifications

Add new 10.6.0 release, migrating download of source to use Geant4's
public release repo on CERN GitLab. Change versioning scheme to use
clearer and standard semantic scheme.

Update geant4-data and g4XXX data packages with new versions. Migrate
geant4-data as a BundlePackage of the g4XXX packages, installing links
to each under a single directory under share for geant4-data. Ensure
each g4XXX package exports the environment variable pointing to its
location expected by Geant4.

Remove "data" variant from Geant4 package and always use geant4-data.

Simplify cxxstd variant transport to dependencies.

* g4<DATA>: Use self to resolve correct prefix

* geant4, data: Fix flake8 errors

* g4photonevaporation: flake8 fix

* geant4: vecgeom version depends_on

Geant4 major.minor versions have specific dependencies on vecgeom
versions. Add missing vecgeom version for geant4 10.5, and match
version requirements for vecgeom in geant4 depends_on.

* geant4: c++17 patch specific for 10.4.3

* geant4: simplify geant4-data setup

* geant4: Use new define_from_variant function
