e13ac6cd7e Restore ABI compatibility, broken in r273127. Note that while this fixes 
ABI with 10.1, it breaks ABI for 11-CURRENT, so rebuild of automountd(8)
is neccessary.

1687a6636a 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).

f820ba5865 Make autofs timeout handling use timeout task instead of callout; 
that's because the handler can sleep on sx lock.

49648b28cf 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

bf5f21dde4 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.

347e2b6e44 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.

cac9beab7d 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.
