libstdc++ before gcc r244057 expected that libc provided
__cxa_thread_atexit_impl, and libstdc++ implemented
__cxa_thread_atexit, by forwarding the calls to _impl. Mentioned gcc
revision checks for __cxa_thread_atexit in libc and does not provide
the symbol from libstdc++ if found.
This change helps older gcc, in particular, all released versions
which implement thread_local, by consolidating the implementation into
libc. For that versions, if configured with the current libc, the
__cxa_thread_atexit is exported from libstdc++ as a trivial wrapper
around libc::__cxa_thread_atexit_impl.
The __cxa_thread_atexit implementation is put into separate source
file to allow for static linking with older libstdc++.a.

This is preparation work for 11ac support. The regulatory database
needs to know about VHT channel flags and 80MHz (and later 160MHz)
available channel bands.
Whilst here, add the 2GHz VHT band (which is a terrible, terrible vendor
extension that almost all vendors do) just in preparation, even though
I don't (yet) plan on supporting it.
the mapping which might be accessed by other threads.
If a pointer to the /dev/hpet register page mapping was stored into
the hpet_dev_map, other threads might access the page at any time.
Never unmap it, instead, keep track of mappings for all hpet units in
smal array. Store pointer to the newly mapped registers page using
CAS, to detect parallel mappings.
It appeared relatively easy to demonstrate the problem by arranging
two threads which perform gettimeofday(2) concurently, first time in
the process address space, when HPET is used for timecounter.

The following files are new with this commit:

They are not connected to build, but were kept in tree for reference
for future maintenance.
All our local trivial changes were applied to contrib/zlib, and the
contrib/zlib vendor source code is intended to 100% match lib/libz

As a followup to r310638, update libsysdecode (and kdump) to decode the
'mode' argument to getfsstat(). sysdecode_getfsstat_flags() has been
renamed to sysdecode_getfsstat_mode() and now treats the argument as an
enumerated value rather than a mask of flags.
Change ksw_used and ksw_total to unsigned, which increases the maximum
total swap that can be displayed properly from ~8TB to ~16TB.

Apparently the libstand dosfs optimization is a bit too optimistic
and did introduce possible memory corruption.
This patch is backing out the bad part and since this results in
dosfs reading full blocks now, we can also remove extra offset argument
from dv_strategy callback.
The analysis of the issue and the backout patch is provided by Mikhail Kupchik.

Move llvm-objdump from CLANG_EXTRAS to installed by default
We currently install three tools from binutils 2.17.50: as, ld, and
objdump. Work is underway to migrate to a permissively-licensed
tool-chain, with one goal being the retirement of binutils 2.17.50.
LLVM's llvm-objdump is intended to be compatible with GNU objdump
although it is currently missing some options and may have formatting
differences. Enable it by default for testing and further investigation.
It may later be changed to install as /usr/bin/objdump, it becomes a
fully viable replacement.

This argument is not a bitmask of flags, but only accepts a single value.
Fail with EINVAL if an invalid value is passed to 'flag'. Rename the
'flags' argument to getmntinfo(3) to 'mode' as well to match.

This change consists of two parts:
- allow libkvm to recognize /dev/vmm/* character devices as devices that
provide access to the physical memory of a system (similarly to /dev/fwmem*)
- allow libkvm to recognize that /dev/vmm/* and /dev/fwmem* devices provide
access to the physical memory of live remote systems and, thus, the memory
is writable
As a result, it should be possible to run commands like
$ kgdb -w /path/to/kernel /dev/fwmem0.0
$ kgdb /path/to/kernel /dev/vmm/guest

more discussion/review.
In particular, many parties were concerned over introducing a
non-standard format qualifier to *printf(3) which didn't already
exist in other OSes, e.g. Linux, thus making code which used %b
harder to port to other operating systems.

This is a direct port of the kernel %b format.
I'm unclear on if (more) non-portable printf extensions will be a
problem. I think it's desirable to have userspace formats include all
kernel formats, but there may be competing goals I'm not aware of.

Add a helper routine for opening a directory that is restricted to being
used for opening relative files as stdio streams.
I think this will really help basic adaptation of multi-file programs to
Capsicum. Rather than having each program initialize a rights object and
ioctl/fcntl arrays for their root fd for relative opens, consolidate in the
logical place.
