drop any frames that arrive while the device is starved for receive buffers.
This makes the receive path to only execute in context of the receive thread
and allows for further simplification.

work in FreeBSD.
This is still heavily a work in progress but I'd rather it start
shipping in -HEAD sooner rather than later.
This doesn't (yet) link it into the build system either for a static
kernel or as a module; that will come later (after many, many make universe
tests.)
By using __has_extension(c_generic_selections), we can explicitly test
whether we're dealing with a version of Clang that supports _Generic().
That way we can use the improved <tgmath.h> code, even when not using
-std=c11. This massively reduces the compilation time when invoking
these functions.
* Don't call the _fast version of the TLS accessor in terminate() or
unexpected().
1) TLS may not have been set up yet.
2) When we're in one of these functions, Really Bad Stuff has
happened and potentially saving a few cycles really isn't
important.
* Merge in fixes from FreeBSD trunk to make atomics work with recent
clang.

* Fix a copy-and-paste error when setting the unexpected exception handler
(actually set the terminate handler by mistake).
* Fix some warnings.

When syslogd forks a process for '|' destinations, it closes all file
descriptors greater than 2.
Use closefrom() for this instead of a getdtablesize()/close() loop because
it is both faster and avoids leaving file descriptors open because the limit
was lowered after they were opened.

Remove ADA_FLAG_PACK_INVALID flag. Since ATA disks have no concept of media
change it only duplicates CAM_PERIPH_INVALID flag, so we can use last one.
Slightly cleanup DA_FLAG_PACK_INVALID use.
Give periph validity flag own periph reference. That slightly simplifies
the release logic and covers hypothetical case if lock is dropped inside
the periph_oninval() method.
If max_sg_length is 0, then we default to 16
If max_sg_length is less than CISS_MAX_SG_ELEMENTS, then
we will set round the value of max_sg_length to the nearest
power of 2 and use it to align maxio.
Else, we will use CISS_MAX_SG_ELEMENTS for our calculations.
Thanks to scottl for working me through the history and providing
the basis for this patch.

As of r249959, we want to build with IDEA support enabled
unconditionally. As this change removed the MK_IDEA flag, update these
Makefiles accordingly.
Clang only supports atomic operations for ARMv6. For non-ARMv6, we still
need to emit these functions.
Clang's prototype for these functions slightly differs, as it is truly
based on GCC's documentation. It requires the use of signed types, but
also requires varargs. Still, we are not allowed to simply implement
this function directly. Cleverly work around this by implementing it
under a different name and using __strong_reference().
The European version of the patent expired in 2011.
The US version of the patent expired in 2012 or prior.

X11 side of things from bleeding into Xdialog(1) stderr output). It should
be duely noted that such errors are not a by-product of anything in the
Xdialog(1) utility or API, but optional libraries that it can link against
(such as Gtk1 versus Gtk2; if you compile xdialog from ports against Gtk2
AND misconfigure your fonts or generally make Gtk2 unhappy, these warning
messages can bleed into the captured stderr -- that is we we sanitize!).
'install' since it breaks buildworld after the introduction and
use of 'install -l' in r245752. Overriding INSTALL causes
/usr/bin/install to be used instead of the proper
/usr/src/tools/install.sh which handles the new flag.

piece them together from multiple reads(). It's as if /dev/devctl is
a datagram device instead of a stream device. However, devd's
internal buffer was too small (1025 bytes) to read an entire
ereport.fs.zfs.checksum event (variable, up to ~1300 bytes). This
commit enlarges the buffer to 8k.
