932ef5b5cd Reintroduce the snp(4) driver. 
Because the TTY hooks interface was not finished when I imported the
MPSAFE TTY layer, I had to disconnect the snp(4) driver. This snp(4)
implementation has been sitting in my P4 branch for some time now.
Unfortunately it still doesn't use the same error handling as snp(4)
(returning codes through FIONREAD), but it should already be usable.

I'm committing this to SVN, hoping someone else could polish off its
rough edges. It's always better than having a broken driver sitting in
the tree.

2e37c8eacb Convert the snp(4) driver to use cdevpriv. 
Now we have a single /dev/snp device node, which can be opened by
watch(8) multiple times. Even though snp(4) will be dead as of next
week, it's nice having this in SVN, because:

- We may want to MFC it to RELENG_7.
- By the time we fix snp(4) again, it's already there, existing watch(8)
  binaries should already work.

Just like bpf(4), I'm adding a symlink from snp0 to snp to remain binary
compatible.

0987daa1f8 Remove the stuff about only the superuser being able to use this (see 
snp.c 1.64), and add a note to the BUGS section warning the reader
that this manual page is stale and may be inaccurate.

watch(8) will try to help them by loading the module.

1130b656e5 Make the long-awaited change from $Id$ to $FreeBSD$ 
This will make a number of things easier in the future, as well as (finally!)
avoiding the Id-smashing problem which has plagued developers for so long.

Boy, I'm glad we're not using sup anymore.  This update would have been
insane otherwise.
