Add an extra stat call to the "delay" function in addition to the

to help a lot more to mitigate the unrelated kernel race seen.

This allows all of the athstats statistics to work again.
Specifics:
* The previous code used chars < 0x80 as printable, and chars >= 0x80
as "statistics"
* .. which meant any statistic above 127 would wrap around to 0;
* .. so once I added the 802.11n TX/RX statistics to athstats, the tail
end of the statistics list weren't accessible.
This patch:
* adds a define which represents the magic character, rather than a hard
coded one
* the statistic in question is little endian encoded after the magic
character.
Notes:
* statfoo is useful enough to possibly warrant turning into a library API.
receive and forward path tagging packets with both the ifconfig fib
option or using ipfw, running ICMP6, TCP/v6 and UDP/v6 tests and
testing both setfib(2) as well as the SO_SETFIB socket option.
At 16 FIBs a total of over 64k return codes/replies/stati are checked,
sometimes multiple times (in different ways, e.g. the reflected request
as well as ipfw counter values).
The scripts need two or three machines to run and are thus not added
to the tools/regression framework but only to tools/test.

The default is to wait after each counter is tested. Since the prompt

The program will verify that all counters fire and that the code neither
panics the system nor locks it up. This should be considered a first pass
conformance test for new sets of counters being added to hwpmc(4).
At first, I added a utility called utxrm(8) to remove stale entries from
the user accounting database. It seems there are cases in which we need
to perform different operations on the database as well. Simply rename
utxrm(8) to utx(8) and place the old code under the "rm" command.
In addition to "rm", this tool supports "boot" and "shutdown", which are
going to be used by an rc-script which I am going to commit separately.
TUNABLE variable (hw.netmap.buf_size) so we can experiment

- rearrange the memory allocation code so it will be easier
to replace it with a different implementation. The current code
relies on a single large contiguous chunk of memory obtained through
contigmalloc.
The new implementation (not committed yet) uses multiple
smaller chunks which are easier to fit in a fragmented address
space.
If the sentence starts with a multiple of eight spaces, the sentence
should in almost all practical cases have started with tabs instead.
Replace these spaces by tabs.
This small utility can be used to `sanitize' the whitespace in source
code. It does the following things:
Global:
- Remove empty lines at the beginning and the end of a file.
- Merge successive empty lines into a single empty line.
Per-line:
- Remove trailing whitespace.
- Merge spaces preceeding tabs into the tabs.
It operated on stdin/stdout. This means that if you use vi(1), you can
just run :%!fixwhite to reorganize the file.

More fine-grained control is provided via MK_SOURCELESS_HOST (for native code
that runs on host CPU) and MK_SOURCELESS_UCODE (for microcode).

expressions properly. Some of the tests depend on the compiler
implementing C99's FENV_ACCESS pragma, and only commercial compilers
do; those tests are currently skipped. If any of the enabled tests
fail, then odds are the libm regression tests will fail also.
This should make it easier to diagnose reported problems on platforms
I don't have.
Currently, gcc passes all the tests that don't depend on FENV_ACCESS
on amd64 and sparc64. Clang fails a few on amd64 (see clang bug
11406). Both gcc and clang fare poorly on i386, which has well-known
issues.
Before this fix, only the first statement of the trap was executed if

Also, rework evalcase() to not evaluate any tree. Instead, return the
NCLISTFALLTHRU node and handle it in evaltree().
Fixed bugs:
* If a ;& list with non-zero exit status is followed by an empty ;; or final
list, the exit status of the case command should be equal to the exit
status of the ;& list, not 0.
* An empty ;& case should not reset $?.
* If no pattern is matched, POSIX says the exit status shall be 0 (even if
there are command substitutions).
* If a pattern is matched and there are no command substitutions, the first
command should see the $? from before the case command, not always 0.

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.
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).
