abd2ba58f2 Take back the name 'bridge' now that we are the one and only. This can be
phased back in over the next few major releases. if_bridge is still the
documented device name so nothing has changed yet.

42dfc78150 In some particular cases (like in pccard and pccbb), the real device
handler is wrapped in a couple of functions - a filter wrapper and an
ithread wrapper. In this case (and just in this case), the filter
wrapper could ask the system to schedule the ithread and mask the
interrupt source if the wrapped handler is composed of just an ithread
handler: modify the "old" interrupt code to make it support
this situation, while the "new" interrupt code is already ok.

e12a0ce02f Last major commit and updates for RELENG_7:
- Rework the entire pcm_channel structure:
  * Remove rarely used link placeholder, instead, make each pcm_channel
    as head/link of each own/each other. Unlock - Lock sequence due to
    sleep malloc has been reduced.
  * Implement "busy" queue which will contain list of busy/active
    channels. This greatly reduce locking contention for example while
    servicing interrupt for hardware with many channels or when virtual
    channels reach its 256 peak channels.

- So I heard you like v chan ... O RLY?
  Welcome to Virtual **Record** Channels (vrec, rec vchans, vchans for
  recording, Rec-Chan, you decide), the ultimate solutions for your
  nagging O_RDWR full-duplex wannabe (note: flash plugins) monopolizing
  single record channel causing EBUSY.  Vrec works exactly like Vchans
  (or, should I rename it to "Vplay" :) , except that it operates on the
  opposite direction (recording). Up to 256 vrecs (like vchans) are
  possible.

  Notes:
   * Relocate dev.pcm.%d.{vchans,vchanformat,vchanrate} to each of its
     respective node/direction:
       dev.pcm.%d.play.* for "play"   (cdev = dsp%d.vp%d)
       dev.pcm.%d.rec.*  for "record" (cdev = dsp%d.vr%d)
   * Don't expect that it will magically give you ability to split
     "recording source" (eg: 1 channel for cdrom, 1 channel for mic,
     etc). Just admit that you only have a *single* recording source /
     channel. Please bug your hardware vendor instead :)

- Bump maxautovchans from 4 to 16. For a full-fledged multimedia
  desktop/workstation with too many soundservers installed (esound,
  artsd, jackd, pulse/polypaudio, ding-dong pling plong mudkip fuh fuh,
  etc), 4 seems inadequate. There will be no memory penalty here, since
  virtual channels are allocate only by demand.

- Nuke/Rework the entire statically created cdev entries. Everything is
  clonable through snd own clone manager which designed to withstand many
  kind of abusive devfs droids such as:
      * while : ; do /bin/test -e /dev/dsp ; done
      * jot 16777216 0 | while read x ; do ls /dev/dsp0.$x ; done
      * hundreds (could be thousands) concurrent threads/process opening
	"/dev/dsp" (previously, this might result EBUSY even with just
	3 contesting threads/procs).
  o Reusable clone objects (instead of creating new one like there's no
    tomorrow) after certain expiration deadline. The clone allocator will
    decide whether to reuse, share, or creating new clone.
  o Automatic garbage collector.

- Dynamic unit magic allocator. Maximum attached soundcards can be tuned
  using tunable "hw.snd.maxunit" (Default to 512). Minimum is 16, and
  maximum is 2048.

- ..other fixes, mostly related to concurrency issues.

joel@ will do the manpage updates on sound(4).

Have fun.

d3b7ba40ef Export quad symbols. They were previously commented out. These symbols
really shouldn't be exported since they should be pulled from libgcc, but
the build of some applications is broken and they expect to see them in
libc.  glibc exports these symbols, although Solaris doesn't appear to,
so export them for compatibility's sake.

f291262336 Some libc symbol map cleanups.
net: endhostdnsent is named _endhostdnsent and is
  private to netdb family of functions.

  posix1e: acl_size.c has been never compiled in,
  so there's no "acl_size".

  rpc: "getnetid" is a static function.

  stdtime: "gtime" is #ifdef'ed out in the source.

  some symbols are specific only to some architectures,
  e.g., ___tls_get_addr is only defined on i386.

  __htonl, __htons, __ntohl and __ntohs are no longer
  functions, they are now (internal) defines in
  <machine/endian.h>.

7f276f0bff Now that sx(9) locks support an interruptible lock acquire primitive,
properly observe the SB_NOINTR flag in sblock.  This restores the
required behavior that lock acquisition be interruptible on the socket
buffer I/O serialization lock to allow threads waiting for I/O to be
signaled even if they aren't the thread currently holding the I/O lock.
With this change, the sblock regression test is again passed.

d5fdf88def Add functions sx_xlock_sig() and sx_slock_sig().
These functions are intended to do the same actions of sx_xlock() and
sx_slock() but with the difference to perform an interruptible sleep, so
that sleep can be interrupted by external events.
In order to support these new featueres, some code renstruction is needed,
but external API won't be affected at all.

Note: use "void" cast for "int" returning functions in order to avoid tools
like Coverity prevents to whine.

 - ICH8 systems autoneg to 100 rather than 1000, this can also be

patch:
- Do the correct test for ldt allocation
- Drop dt_lock just before to call kmem_free (since it acquires blocking
  locks inside)
- Solve a deadlock with smp_rendezvous() where other CPU will wait
  undefinitively for dt_lock acquisition.
- Add dt_lock in the WITNESS list of spinlocks

While applying these modifies, change the requirement for user_ldt_free()
