7e6cabd06e Renumber copyright clause 4
Renumber cluase 4 to 3, per what everybody else did when BSD granted
them permission to remove clause 3. My insistance on keeping the same
numbering for legal reasons is too pedantic, so give up on that point.

f291714326 Remove name length limitation from autofs(5). The linear search with
strlens is somewhat suboptimal, but it's a temporary measure that will
be replaced with red-black trees later on.

faec271eeb Fix autofs triggering problem. Assume you have an NFS server,
192.168.1.1, with share "share". This commit fixes a problem
where "mkdir /net/192.168.1.1/share/meh" would return spurious
error instead of creating the directory if the target filesystem
wasn't mounted yet; subsequent attempts would work correctly.

The failure scenario is kind of complicated to explain, but it all
boils down to calling VOP_MKDIR() for the target filesystem (NFS)
with wrong dvp - the autofs vnode instead of the filesystem root
mounted over it.

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).

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.
