Make the iSCSI stack use __FBSDID() properly.

MFC r256800: pathchk: Ensure bytes >= 128 are considered non-portable
characters.

This was not broken on architectures such as ARM where char is unsigned.

Also, remove the first non-portable character from the output. POSIX does
not require this, and printing the first byte may yield an invalid byte
sequence with UTF-8.

MFC r270096:

Bring in the new automounter, similar to what's provided in most other
UNIX systems, eg. MacOS X and Solaris.  It uses Sun-compatible map format,
has proper kernel support, and LDAP integration.

There are still a few outstanding problems; they will be fixed shortly.

MFC r270402:

Autofs softc needs to be global anyway, so don't pass it as a local
variable, and don't store in autofs_mount.  Also rename it from 'sc'
to 'autofs_softc', since it's global and extern.
