Remove svn:mergeinfo from the releng/10.0 branch.

After branch creation from stable/10, the stable/10 branch mergeinfo
was moved to the root of the branch.

Since there have not been any merges from stable/10 to releng/10.0
yet, we do not need to track any of the existing mergeinfo here.

Merges to releng/10.0 should now be done to the root of the branch.

For future branches during the release cycle, unless otherwise noted,
this change will be done as part of the stable/ and releng/ branch
creation.

- Copy stable/10 (r259064) to releng/10.0 as part of the
10.0-RELEASE cycle.
- Update __FreeBSD_version [1]
- Set branch name to -RC1

[1] 10.0-CURRENT __FreeBSD_version value ended at '55', so
start releng/10.0 at '100' so the branch is started with
a value ending in zero.

Zap now-unused SHLIB_MINOR

Supply SMB_CFG_FILE in CFLAGS. The newly imported smbfs-1.4.2
allows us to supply our own value for this, overriding the
default /usr/local/etc/nsmb.conf, which is not appropriate for
base system configuration files.

Add bmake glue for src/contrib/smbfs and connect userland smbfs
support to the build.

The MFC reminder below is subject to <re@FreeBSD.org> approval
