d78200e4e8 Refactor contigmalloc() into two functions: a simple front-end that deals
with the malloc tag and calls a new back-end, kmem_alloc_contig(), that
allocates the pages and maps them.

The motivations for this change are two-fold: (1) A cache mode parameter
will be added to kmem_alloc_contig().  In other words, kmem_alloc_contig()
will be extended to support the allocation of memory with caller-specified
caching. (2) The UMA allocation function that is used by the two jumbo
frames zones can use kmem_alloc_contig() in place of contigmalloc() and
thereby avoid having free jumbo frames held by the zone counted as live
malloc()ed memory.

d50c1d79d0 Changes to the NR-Sack code so that:
1) All bit disappears
2) The two sets of gaps (nr and non-nr) are
   disjointed, you don't have gaps struck in
   both places.

This adjusts us to coorespond to the new draft. Still
to-do, cleanup the code so that there are only one set
of sack routines (original NR-Sack done by E cloned all
sack code).

651175c9db Introduce support for adaptive spinning in lockmgr.
Actually, as it did receive few tuning, the support is disabled by
default, but it can opt-in with the option ADAPTIVE_LOCKMGRS.
Due to the nature of lockmgrs, adaptive spinning needs to be
selectively enabled for any interested lockmgr.
The support is bi-directional, or, in other ways, it will work in both
cases if the lock is held in read or write way.  In particular, the
read path is passible of further tunning using the sysctls
debug.lockmgr.retries and debug.lockmgr.loops .  Ideally, such sysctls
should be axed or compiled out before release.

Addictionally note that adaptive spinning doesn't cope well with
LK_SLEEPFAIL.  The reason is that many (and probabilly all) consumers
of LK_SLEEPFAIL are mainly interested in knowing if the interlock was
dropped or not in order to reacquire it and re-test initial conditions.
This directly interacts with adaptive spinning because lockmgr needs
to drop the interlock while spinning in order to avoid a deadlock
(further details in the comments inside the patch).

Final note: finding someone willing to help on tuning this with
relevant workloads would be either very important and appreciated.

eaaaf1906b Perform some more cleanups to in-kernel session handling.
The code that was in place in exit1() was mainly based on code from the
old TTY layer. The main reason behind this, was because at one moment I
ran a system that had two TTY layers in place at the same time. It is
now sufficient to do the following:

- Remove references from the session structure to the TTY vnode and the
  session leader.

- If we have a controlling TTY and the session used by the TTY is equal
  to our session, send the SIGHUP.

- If we have a vnode to the controlling TTY which has not been revoked,
  revoke it.

While there, change sys/kern/tty.c to use s_ttyp in the comparison
instead of s_ttyvp. It should not make any difference, because s_ttyvp
can only become null when the session leader already left, but it's
nicer to compare against the proper value.

c4f16b69e1 Add a new 'void closefrom(int lowfd)' system call. When called, it closes
any open file descriptors >= 'lowfd'.  It is largely identical to the same
function on other operating systems such as Solaris, DFly, NetBSD, and
OpenBSD.  One difference from other *BSD is that this closefrom() does not
fail with any errors.  In practice, while the manpages for NetBSD and
OpenBSD claim that they return EINTR, they ignore internal errors from
close() and never return EINTR.  DFly does return EINTR, but for the common
use case (closing fd's prior to execve()), the caller really wants all
fd's closed and returning EINTR just forces callers to call closefrom() in
a loop until it stops failing.

Note that this implementation of closefrom(2) does not make any effort to
resolve userland races with open(2) in other threads.  As such, it is not
multithread safe.

9c373a81a3 Make tcsetsid(3) work on revoked TTYs.
Right now the only way to make tcsetsid(3)/TIOCSCTTY work, is by
ensuring the session leader is dead. This means that an application that
catches SIGHUPs and performs a sleep prevents us from assigning a new
session leader.

Change the code to make it work on revoked TTYs as well. This allows us
to change init(8) to make the shutdown script run in a more clean
environment.

164e1f20ec - Add a way to change filter oversampling factor through
FEEDER_RATE_PRESET "OVERSAMPLING_FACTOR:X .. .." where
  X = log2(oversampling factor).

- Lower down default filter oversampling factor from 128
  (log2 = 7) to 32 (log2 = 5), saving worth of 80 Kb.
  The use of better polynomial interpolator will raise
  its conversion quality/accuracy to match (or slightly
  better) with previous settings.
