This uses the existing crunchgen infrastructure to build
a series of tools designed to replace the base and networking
tools on an embedded system.
It reuses 'bsd.crunchgen.mk' to drive the actual file
creation. The rescue build system also uses this.
Unlike busybox, it doesn't include its own source - instead,
it just builds from the sources in /usr/src/ and leverages
the existing BSD framework.
Thie is still quite messy and could do with a whole lot of
cleaning up. However it is proving to be very useful with
my current build framework, allowing me to build binary root
images that are about 30% less than simply cherrypicking files
and libraries from an installworld.
so pid files can be written in /var/run when started as root.
I do not expect this to cause any security issues, but if anyone objects
it could be easily reverted.

than or equal to rcv_adv and fix tcp_twstart() to handle this case by
assuming the last window was zero rather than a negative value.
The code in tcp_input() already safely handled this case. It can happen
due to delayed ACKs along with a remote sender that sends data beyond
the window we previously advertised. If we have room in our socket buffer
for the extra data beyond the advertised window, we will accept it.
However, if the ACK for that segment is delayed, then we will not
effectively fixup rcv_adv to account for that extra data until the
next segment arrives and forces out an ACK. When that next segment
arrives, rcv_nxt will be beyond rcv_adv.

Things such as "sh" require local tools to be built before
cross-compiling. This allows for extra software (that's
built via LOCAL_DIRS) to also have a build-tools target where
required.
These files contained various combinations of Big5, eucJP and KOI8-U
encoded strings. The byte representations of their respective encodings
have been translated to $'...' escape sequences as understood by our sh(1).

It's too late to change this in 9.0 -- so we have a release with the
misspelling in the wild and should not break users that depend on it.
Deprecating/replacing it because of a one-char typo seems excessive.
recoverdisk(1) wants to know about read errors when doing the 1MB/64k
reads as fast as possible so it can continue and retry them later with
smaller reads (down to sector size). Any retries by lower layers will
only slow it down.

This switches us to using -isoC-2011 as the symbol name which is used by
groff and mdocml. It follows the change to 4 digit years as done with
IEEE Std 1003 post-1999.

interface address lists that distinguish read locks from write locks.
To preserve the KPI, the previous operations are mapped to the write
lock macros. The lock is still kept as a mutex for now.

It turns out our GCC has quite an interesting bug:
typeof(1.0fi) != float _Complex
typeof((float _Complex)1.0fi) != float _Complex
typeof((float _Complex)1.0i) == float _Complex
In other words: if casting to an equal size, GCC seems to take a
shortcut. By casting down from a double to a float, GCC doesn't take
this shortcut, yielding the proper type.
To prevent foot-shooting, add a _Static_assert() to guarantee that
_Complex_I is always a float _Complex. I'm not going to MFC this part of
the diff.

The macro construction used now, is almost identical to the code
provided in C11 proposal N1404. This new version doesn't seem to
introduce any regressions according to the regression test in tools/,
but still seems to malfunction with Clang on certain aspects.
The new code does work successfully with GCC 4.2, 4.6 and 4.7. With 4.7,
it also works when __generic() is implemented on top of _Generic().

Already introducing this allows us to be forward compatible with C11
compilers. By implementing <tgmath.h> on top of this interface, it
becomes trivial to support both our existing GCC and newer compilers.
This allows people to still write statically linked applications that
call strchr() or strrchr() and have a local variable or function called
index.

For now, AH_SUPPORT_AR5416 is required, so I'll just fix any
