The OpenAFS servers can't be started without asetkey so it should be
included in the -server package along with the akeyconvert command.

* Bumped to 1.6.22, includes security fix
* Also includes a patch that addresses the getpwd() ENOENT issue for
  RHEL 7.4 kernels.

The transarc-client package creates a symlink for the client cache,
but if it already exists, then the RPM fails to install with a cpio
error.  This fixes the package, by moving the directory out of the way
before starting the transaction.

The openafs-client.service in the upstream repo doesn't handle the
way afsd forks off a daemon.  Added RemainAfterExit=yes and
GuessMainPID=no to the service unit.  Inspiration from Debian systemd
unit, found here:

http://anonscm.debian.org/cgit/pkg-k5-afs/openafs.git/tree/debian/openafs-client.service?id=debian/1.6.11.1-1

* Add openafs-kmod.spec to build just the kmod-openafs and
dkms-openafs packages.
* Add a custom kmodtool script to use to build the template for the
kmod-openafs package
* Use the 'find-installed-kversion.sh' script to automatically
generate the kernel dependency based on what version of the
kernel-headers package is installed (works in a mock chroot)

The RPM find-provides script looks for library files that are
executable (chmod +x).  This change makes sure that all the library
files in libdir are executable.  The resulting RPMs will have their
library names added in the Provides: section.

Use configuration macros for building software, update cacheinfo

Previous commits uses a directory /etc/sysconfig/openafs instead of
/etc/openafs, which is in line with how Debian packages are built.  In
an attempt to keep things similar to debian, use /etc/openafs/ for
client configuration, and /etc/openafs/server/ for server
configuration.

Compatibility links are updated to reflect this change.

* Use %configure instead of ./configure, which pre-populates prefix,
libdir, bindir, etc to Red Hat defaults
* Override sysconfdir to be %{_sysconfdir}/sysconfig so everything
looks in /etc/sysconfig/openafs/ for configuration files.

Fix paths that use transarc locations, add compatibility packages

* Re-add the -compat subpackage from upstream
* Create two -transarc packages
** Client: contains /usr/vice/ symlinks
** Server: contains /usr/afs/ symlinks

* Fix the systemd unit so it uses the system paths instead of transarc
paths.
* Include the correct paths in the files section
* Define the cache directory in the client package
* Mark the CellServDB files as config files
