- 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.

Start using the 'init_static_kenv()' API provided by r198561 to initialize
CFE environment variables.

Using svn cp rather than cp to copy these files over had the benefit
of preserving their history. It had the problem that it also copied
over mergeinfo data. Since we're retiring the projects/mips branch,
I'm removing the svn:mergeinfo property from them all.

Merge from projects/mips to head by hand:

copy over cfe_env.c...

Merge in new cfe environment passing of kenv for swarm/sibyte boards.
