265f940acc Change some headers such that lang/gcc* ports no longer patch them.
The lang/gcc* ports patch headers where they think something is
non-standard. These patched headers override the system headers which means
you have to rebuild these ports whenever you do installworld to make sure
they contain the latest changes.

82dd5016bd Cleanup of xlocale:
- Address performance regressions encountered by das@ by caching per-thread
  data in TLS where available.
- Add a __NO_TLS flag to cdefs.h to indicate where not available.
- Reorganise the xlocale.h definitions into xlocale/*.h so that they can be
  included from multiple places.
- Export the POSIX2008 subset of xlocale when POSIX2008 says it should be
  exported, independently of whether xlocale.h is included.
- Fix the bug where programs using ctype functions always assumed ASCII unless
  recompiled.
- Fix some style(9) violations.

9b1246ca38 Fix a bug where the wrong protocol overhead was used. This can lead
to a deadlock of an association when an IPv6 socket was used to
communcate with IPv4 and an ICMPv4 fragmentation needed message
was received.
While there, simplify the code a bit.

5525b53de5 Do not handle MOD_SHUTDOWN equally to MOD_UNLOAD in sound kernel module.
MOD_SHUTDOWN is not an end of existence, and there is a life after it.
In particular, code previously called on MOD_SHUTDOWN grabbed lock and
deallocated unit numbering. That caused infinite wait loop if snd_uaudio
tried to destroy its PCM device after that point.

bb631bf94d - As it turns out, MSI-X is broken for at least LSI SAS1068E when passed
through by VMware so blacklist their PCI-PCI bridge for MSI/MSI-X here.
  Note that besides currently there not being a quirk type that disables
  MSI-X only and there's no evidence that MSI doesn't work with the VMware
  pass-through, it's really questionable whether MSI generally works in
  that setup as VMware only mention three know working devices [1, p. 4].
  Also not that this quirk entry currently doesn't affect the devices
  emulated by VMware in any way as these don't claim support MSI/MSI-X to
  begin with. [2]
  While at it, make the PCI quirk table const and static.
- Remove some duplicated empty lines.
- Use DEVMETHOD_END.

* Change the mesh IE size to be IEEE80211_MESH_CONF_SZ rather than the
  size of the structure;
* conf_cap is now a uint8_t rather than a uint16_t (uint16_t in D3.0,
  uint8_t in the amendment spec);
* Update mesh config capability bits - earlier bits were from draft X,
  current is amendment spec;
* Update the following to be an enum rather than #define and added
  a VENDOR entry too from the amendment spec;
  IEEE80211_MESHCONF_PATH_*
  IEEE80211_MESHCONF_METRIC_*
  IEEE80211_MESHCONF_CC_*

  IEEE80211_MESHCONF_AUTH_*
* Kept IEEE80211_MESHCONF_FORM_* and IEEE80211_MESHCONF_CAP_* as
  defines because they are defined in a way that we need to mask in/out
  information;
* In IEEE80211_MESHCONF_CAP_* IEEE80211_MESHCONF_CAP_TBTTA is removed

1707b4455f Fix panic after "WARNING - ATA_IDENTIFY taskqueue timeout"
When performing a firmware upgrade via atacontrol[1] the subsequent
command may time out producing the error message above.  When this
happens the callout could still be active, and the system would then
panic due to a destroyed semaphore.

Instead, ensure that the callout is done first, via callout_drain.

Note that this fix applies to the "old" ata(4) and so isn't applicable
to the default configuration in HEAD.  It is still applicable to
stable/8.

807675317e Attempt to address some potential vap->iv_bss race conditions.
There are unfortunately a number of situations where vap->iv_bss is changed
or freed by some code in net80211.  Because multiple threads can concurrently
be doing work (and the vap->iv_bss access isn't at all done behind any kind
of lock), it's quite possible that:

* a change will occur in one thread - eg, by a call through
  ieee80211_sta_join1();
* a state change occurs in another thread - eg an RX is scheduled
  in the ath tasklet and it calls ieee80211_input_mimo_all(), which
  does dereference vap->iv_bss;
* these two executing concurrently, causing things to explode.

Another instance is ath_beacon_alloc() which takes an ieee80211_node *.
It's called with the vap->iv_bss node from ath_newstate(). If the node has
changed in the meantime (say it's been freed elsewhere) the reference
that it grabbed _before_ refcounting it may be stale.

I would _prefer_ that these sorts of things were serialised somewhere but
that may be a bit much to ask.  Instead, the best we can (currently) hope
is that the underlying bss node is still (somewhat) valid.

There is a related PR (kern/164382) described by the first case above.
That should be fixed by properly serialising the RX path and reset path
so an RX can't occur at the same time as the vap free/shutdown path.

This is inspired by some related fixes in r212127.

04016bcf93 Flesh out support for SAS1078 and SAS1078DE (which are said to actually
be the same chip):
- The I/O port resource may not be available with these. However, given
  that we actually only need this resource for some controllers that
  require their firmware to be up- and downloaded (which excludes the
  SAS1078{,DE}) just handle failure to allocate this resource gracefully
  when possible. While at it, generally put non-fatal resource allocation
  failures under bootverbose.
- SAS1078{,DE} use a different hard reset protocol.
- Add workarounds for the 36GB physical address limitation of scatter/
  gather elements of these controllers.

The set of the flag is not neccessary there, because the only current
user of the cpu_set_user_tls() is create_thread(), which calls
cpu_set_upcall() before and cpu_set_upcall() itself sets PCB_FULL_IRET.
