4cdc52bdef Make automountd(8) inform autofs(4) whether directory being handled can 
have wildcards.  This makes it possible for autofs(4) to avoid requesting
automountd(8) action on access to nonexistent nodes - unless wildcards
are actually used.

Note that this change breaks ABI for automountd(8).

759489f9e2 Make autofs timeout handling use timeout task instead of callout; 
that's because the handler can sleep on sx lock.

5a66f6b3c4 Fix thinko that, with two map entries like shown below, in that order, 
made autofs mix them up: the second one wasn't visible in ls(1) output,
and trying to access it would trigger mount for the first one.

foobar		host:/foobar
foo		host:/foo

7cb570d0ae Fix bug that, assuming a/ is a root of NFS filesystem mounted on autofs, 
prevented "mv a/from a/to" from working, while "cd a && mv from to" was ok.

f81018caf2 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.

3914ddf8a7 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.
