Allow - be used in the name of a provider. Without this change it's not
possible to specify a gptid in geli_devices.

Remove trailing white space. No functional changes.

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

Add a dummy script, FILESYSTEMS, which depends on root and mountcritlocal
and takes over mountcritlocal's role as the early / late divider. This
makes it far easier to add rc scripts which need to run early, such as a
startup script for zfs, which is right around the corner.

This change should be a no-op; I have verified that the only change in
rcorder's output is the insertion of FILESYSTEMS immediately after
mountcritlocal.

Add scripts for GELI device configuration on boot.

rc.d/geli - configures encryption (ask for passphrases, etc.);
rc.d/geli2 - is called after file systems are mounted and mark devices for
detach on last close.
