- 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.

Remove trailing white space. No functional changes.

As previously discussed, add the svn:executable property to all scripts

Use $required_modules wherever suitable. Use load_kld() in special
cases. So we get rid of quite a few lines of duplicated code.

Don't load geom_md.ko if there is no need to.

Remove the require_kld function I just committed and replace with a nicer solution.

Add two new scripts (mdconfig/mdconfig2) to replace old ramdisk{,-own}
scripts. These scripts handle vnode backed md(4) devices.

Old ramdisk{,-own} scripts will stay a bit in CVS to allow some time for
migration since variable names have changed (ramdisk_* -> mdconfig_*).

Two new variables have been introduced to be able to populate the md(4)
device once it has been mounted (mdconfig_*_files and mdconfig_*_cmd).

Use should be as easy as:

mdconfig_md0="-t malloc -s 10m"
mdconfig_md1="-t vnode -f /var/foo.img"

See rc.conf(5) for more information and description of the additional
variables.
