o Add a MD header private to libc called _fpmath.h; this header
contains bitfield layouts of MD floating-point types.
o Add a MI header private to libc called fpmath.h; this header
contains bitfield layouts of MI floating-point types.
o Add private libc variables to lib/libc/$arch/gen/infinity.c for
storing NaN values.
o Add __double_t and __float_t to <machine/_types.h>, and provide
double_t and float_t typedefs in <math.h>.
o Add some C99 manifest constants (FP_ILOGB0, FP_ILOGBNAN, HUGE_VALF,
HUGE_VALL, INFINITY, NAN, and return values for fpclassify()) to
<math.h> and others (FLT_EVAL_METHOD, DECIMAL_DIG) to <float.h> via
<machine/float.h>.
o Add C99 macro fpclassify() which calls __fpclassify{d,f,l}() based
on the size of its argument. __fpclassifyl() is never called on
alpha because (sizeof(long double) == sizeof(double)), which is good
since __fpclassifyl() can't deal with such a small `long double'.

Insted of embedding a struct g_stat in consumers and providers, merely
include a pointer.
Remove a couple of <sys/time.h> includes now unneeded.
Add a special allocator for struct g_stat. This allocator will allocate
entire pages and hand out g_stat functions from there. The "id" field
indicates free/used status.
Add "/dev/geom.stats" device driver whic exports the pages from the
allocator to userland with mmap(2) in read-only mode.
This mmap(2) interface should be considered a non-public interface and
the functions in libgeom (not yet committed) should be used to access
the statistics data.
so be more careful about calling stackgap_init.

2) Linux_sendmsg was forgetting to fill out the bsd_args struct.

3) The args to linux_connect have differently named types on alpha and
i386, so add a cast to stop gcc complaining.

- Cache temp. keys so they are preserved across suspend/resume (MPI-350)
- Reads and writes are real fast to the MPI-350 causing early timeouts so
wait do some DELAYs to slow things down in the spin loops.
- Stream line setting RIDs when they are better to be set via another
function
- Add better support for setting home key via "ifconfig an0 wepkey 9:<key>"

Add debug.sizeof.g_stat sysctl.
Set the id field of the g_stat when we create consumers and providers.
Remove biocount from consumer, we will use the counters in the g_stat
structure instead. Replace one field which will need to be atomically
manipulated with two fields which will not (stat.nop and stat.nend).
Change add companion field to bio_children: bio_inbed for the exact
same reason.
Don't output the biocount in the confdot output.
Fix KASSERT in g_io_request().
Add sysctl kern.geom.collectstats defaulting to off.
Collect the following raw statistics conditioned on this sysctl:
for each consumer and provider {
total number of operations started.
total number of operations completed.
time last operation completed.
sum of idle-time.
for each of BIO_READ, BIO_WRITE and BIO_DELETE {
number of operations completed.
number of bytes completed.
number of ENOMEM errors.
number of other errors.
sum of transaction time.
}
}
API for getting hold of these statistics data not included yet.
handy if the machine is on another floor. A minor issue with this is that
these functions are also used by the debugger, so its possible to break into
the debugger from the debugger.

correctly tell CAM to requeue the command and then freeze it's queue. The
problem was that when resources became available again, it wouldn't tell
CAM to unfreeze it's queue, so no more commands would ever be delivered.
This is simialr to the bug that was fixed in the cciss driver last year.
This is a bug in 4-STABLE also, but is probably masked by the OS being
fast enough to drain the completion queue before it fills up.
Also add some diagnostics avaialble when compiled with MLY_DEBUG.
Thanks very much to LSI Corp for donating equipment to track this down,
and Vaidus Damosevicius for pestering me long enough to get it fixed.
We may actually be increasing Giant contention doing so because the
actual stuff we do is very cheap.
Also I am not convinced there is not a tiny window for a race here.
Sync with userland test framework which now deals better with pcm feeder kobj
emulation.
Reduce max rate from 96kHz to 48kHz as userland tests found a few bad
points about 90kHz and we don't care about operating up there for now.
