Overhaul of the pcii driver:
. Properly allocate all IO space resources. These cards scatter their
IO addresses over a range of 0x1600 bytes, and they require an
additional address for "special interrupt handling".
. Implement the "special interrupt handling" per the GPIB-PCIIA
Technical Reference Manual; this was apparently not declared for the
clone card this driver has been originally implemented for, but it
turned out to be needed for both, an original NI brand PCII/PCIIA
card as well as the Axiom AX5488 clone.
. Add some diagnostic messages for various resource allocation etc.
failures during probe.
. Add some comments about the structure of the IO address space that
is used by these cards.
Make -U once again honor -D after my change to consolidate setting
of MTREEDB with DESTDIR.

Introduce the new kernel thread called "deadlock resolver".
It is used in order to seek within the threads state and heuristically
understand if there is any deadlock happening.
In order to implement it, the sq_type in sleepqueues is mandatory and not
only compiled along with INVARIANTS option. Additively, a new sleepqueue
function, sleepq_type() is added, returning the type of the sleepqueue
linked to a wchan.
Three new sysctls are added in order to configure the thread:
debug.deadlkres.slptime_threshold
debug.deadlkres.blktime_threshold
debug.deadlkres.sleepfreq
rappresenting the thresholds for sleep and block time that will lead to
a deadlock matching (when exceeded), while the sleepfreq rappresents the
number of seconds between 2 consecutive thread runnings.
In order to enable the deadlock resolver thread recompile your kernel
with the option DEADLKRES.

- Set td_slptick to 0 when moving threads out of sleepqueues.
- Move td_slptick from u_int to int in order to follow 'ticks' signedness
and wrap up accordingly.

Better glibc compatibility for getline/getdelim:
- Tolerate applications that pass a NULL pointer for the buffer and
claim that the capacity of the buffer is nonzero.
- If an application passes in a non-NULL buffer pointer and claims the
buffer has zero capacity, we should free (well, realloc) it
anyway. It could have been obtained from malloc(0), so failing to
free it would be a small memory leak.
Fix a regression that was introduced in r191882.
I changed login_tty() to only work when the application is not a session
leader yet. This works fine for applications in the base system, but it
turns out various applications call this function after daemonizing,
which means they already use their own session.
If setsid() fails, just call tcsetsid() on the current session.
tcsetsid() will already perform proper security checks.

Add ip4.saddrsel/ip4.nosaddrsel (and equivalent for ip6) to control
whether to use source address selection (default) or the primary
jail address for unbound outgoing connections.
This is intended to be used by people upgrading from single-IP
jails to multi-IP jails but not having to change firewall rules,
application ACLs, ... but to force their connections (unless
otherwise changed) to the primry jail IP they had been used for
years, as well as for people prefering to implement similar policies.
Note that for IPv6, if configured incorrectly, this might lead to
scope violations, which single-IPv6 jails could as well, as by the
design of jails. [1]

* Read the pci capability register to identify AGP 3 support
* Add missing smaller aperture sizes for AGP3 chips.
* Fix the aperture size calculation on AGP2 chips.
All sizes between 32M and 256M reported as 256M.
* Add \n to error string.
o Add PCI ID for BCM 5756.

Adapt OpenBSD pf's "sloopy" TCP state machine which is useful for Direct
Server Return mode, where not all packets would be visible to the load
balancer or gateway.
This commit should be reverted when we merge future pf versions. The
benefit it would provide is that this version does not break any existing
public interface and thus won't be a problem if we want to MFC it to
earlier FreeBSD releases.
