autofs: Port autofs from FreeBSD

Brought in basically from
FreeBSD@GitHub cac9beab7d53f0c37ce2a2a1b893be59028928f4
with lots of changes.
Note that this commit isn't necessarily 1:1 with above commit.

Kernel code is basically a rewrite based on the FreeBSD code.
Userspace is basically 1:1 with FreeBSD except that lots of small
changes (including related commits listed below) were necessary.
This is due to autofs being dependent on FreeBSD specific interface,
command options and such.

For userspace, note that non-functional stuff (e.g. whitespace
warnings via git am) are intentionally left to be 1:1 with FreeBSD.
Userspace is basically portable, so don't try to obfuscate the real
changes made for DragonFly by fixing these for now till things are
considered stable unless it's a bug from FreeBSD.

- sys/vfs/autofs - autofs filesystem
- usr.sbin/autofs - autofs userspace command and daemons
