This reverts a private patch which is causing issues with many Intel chipsets.
I will review that patch and see what we need to do to fix it up later, but
for the time being, we will just get these chips working again.
This update contains a lot of code cleanup and is post gem merge
(no, we don't have gem support). It should prove much easier to read the
code now. A lot of thanks goes to vehemens for that work. I have adapted
the code to use cdevpriv for tracking per open file data. That alleviates
the old ugly hack that we used to try and accomplish the task and helped to
clean up the open / close behavior a good bit. This also replaces the hack
that was put in place a year or so ago to prevent radeons from locking up
with AIGLX enabled. I have had a couple of radeon testers report that it
still works as expected, though I no longer have radeon hardware to test with
myself. Other various fixes from the linux crew and Intel, many of
which are muddled in with the gem merge.

- Staticize and locally prototype functions uipc_ctloutput(), unp_dispose(),
unp_init(), and unp_externalize(), none of which have been required
outside of uipc_usrreq.c since uipc_proto.c was removed.
- Remove stale prototype for uipc_usrreq(), which has not existed in the
code since 1997
- Forward declare and staticize uipc_usrreqs structure in uipc_usrreq.c and
not un.h.
- Comment on why uipc_connect2() is still non-static -- it is used directly
by fifofs.
- Remove stale comments, tidy up whitespace.

For the jail case we are already looping over the interface addresses
before falling back to the only IP address of a jail in case of no
match. This is in preparation for the upcoming multi-IPv4/v6/no-IP
jail patch this change was developed with initially.
This also changes the semantics of selecting the IP for processes within
a jail as it now uses the same logic as outside the jail (with additional
checks) but no longer is on a mutually exclusive code path.
Benchmarks had shown no difference at 95.0% confidence for neither the
plain nor the jail case (even with the additional overhead). See:
http://lists.freebsd.org/pipermail/freebsd-net/2008-September/019531.html

SRCDIR is seeded from `pwd` which not only means src/sys/ but
also src/include/ (and possibly src/usr.sbin/amd/include/ ?).
Trying to build world resulted in
===> include (includes)
cd /usr/src/include; make buildincludes; make installincludes

cd: can't cd to /usr/src/include/sys
*** Error code 2
as there is apparently no src/include/sys.
There are multiple possible solutions ranging from seeding SRCDIR from
the environment to adding more substitution patterns.

This changes from a line discipline to the tty_hooks mechanism. Data will come
in directly via rint_bypass and sent to the peer node in a single mbuf.
As line disciplines are no longer used a new netgraph command called
NGM_TTY_SET_TTY is used to attach the tty. This takes a pointer to to the open
file descriptor of the tty and registers the tty hooks. When the tty disappears
the node will shutdown.

Introduce INIT_VNET_*() initializer macros, VNET_FOREACH() iterator
macros, and CURVNET_SET() context setting macros, all currently
resolving to NOPs.
Prepare for virtualization of selected SYSCTL objects by introducing a
family of SYSCTL_V_*() macros, currently resolving to their global
counterparts, i.e. SYSCTL_V_INT() == SYSCTL_INT().
Move selected #defines from sys/sys/vimage.h to newly introduced header
files specific to virtualized subsystems (sys/net/vnet.h,
sys/netinet/vinet.h etc.).
All the changes are verified to have zero functional impact at this
point in time by doing MD5 comparision between pre- and post-change
object files(*).

Note that the change is backwards compatible with the old gvinum configuration
format, but will save the configuration in the new format when the 'saveconfig'
command is executed.

- Update or remove comments that were left over from the original
soreceive_generic() implementation. Quite a few were misleading in the
context of the new code.
- Since soreceive_dgram() has a simpler structure, replace several gotos
with a while loop making the invariants more clear.
- In the blocking while loop, don't try to handle cases incompatible with
the loop invariant (since m is always NULL, don't check for and handle
non-NULL).
- Don't drop and re-acquire the socket buffer lock unnecessarily after
sbwait() returns, which may help reduce lock contention (etc).
- Assume PR_ATOMIC since we assert it at the top of the function.
