MFC r297207:

Make the autofs(5) -hosts map more robust, primarily to make it correctly
handle NFS shares containing whitespace. This also adds the -E parameter
to showmount(8).

PR: 207596
Differential Revision: https://reviews.freebsd.org/D5649

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.
