Fix key delay and repeat, part 2.

Use sbintime_t timeouts with precision control to get very accurate
timing.  It costs little to always ask for about 1% accuracy, and the
not so new event timer implementation usual delivers that, and when
it can't it gets much closer than our previous coarse timeouts and
buggy simple countdown.

The 2 fastest atkbd repeat rates have periods 34 and 38 msec, and ukbd
pretended to support rates in between these.  This requires
sub-microsecond precision and accuracy even to handle the 4 msec
difference very well, but ukbd asked the timeout subsystem for timeouts
of 25 msec and the buggy simple countdown of this gave a a wide range
of precisions and accuracies depending on HZ and other timer
configuration (sometimes better than 25 msec but usually more like 50
msec).  We now ask for and usually get precision and accuracy of about
1% for each repeat and much better on average.

The 1% accuracy is overkill.  Rounding of 30 cps to 34 msec instead of
33 already gives an error of +2% instead of -1%, and ut AT keyboards on
PS/2 interfaces have similar errors.

A timeout is now scheduled for every keypress and release.  This allows
some simplifications that are not done.  It allows removing the timeout
scheduling for exiting polled mode where it was unsafe in ddb mode.  This
is done.  Exiting polled mode had some problems with extra repeats.  Now
exiting polled mode lets an extra timeout fire and the state is fudged
so that the timeout handler does very little.

The sc->time_ms variable is unsigned to avoid overflow.  Differences of
it need to be signed.  Signed comparisons were emulated by testing an
emulated sign bits.  This only works easily for '<' comparisonss, but
we now need a '<=' comparison.  Change the difference variable to
signed and use a signed comparison.  Using unsigned types here didn't
prevent overflow bugs but just reduced them.  Overflow occurs with
n repeats at the silly repeat period of [U]INT_MAX / n.  The old countdown
had an off by 1 error, and the simplifications would simply count down
1 to 0 and not need to accumulate possibly-large repeat repeats.

Fix system hang when large FDT is in use

Summary:
Kernel maps only one page of FDT. When FDT is more than one page in size, data
TLB miss occurs on memmove() when FDT is moved to kernel storage
(sys/powerpc/booke/booke_machdep.c, booke_init())

This introduces a pmap_early_io_unmap() to complement pmap_early_io_map(), which
can be used for any early I/O mapping, but currently is only used when mapping
the fdt.

Fix key delay and repeat, part 1.

kbdcontrol -r fast is documented to give a non-emulated atkbd's fastest
rate of 250.34, but is misimplemented to request this as 0.0.  ukbd
supports many nonstandard rates, although it is currently too inaccurate
by a factor of several hundred for non-huge nonstandard rates to be
useful.  It mapped 0.0 to 200.0.  A repeat delay of 0 means a rate of
infinity which is quite fast, but physical constraints limit this to
a few MHz and the inaccuracies made it almost usable.

Convert 0.0 to the documented 250.34.

Also convert negative args and small args to the 250.34 minimal ones,
like atkbd does.  This is for KDSETREPEAT -- the 2 versions of the
deprecated KDSETRAD have bounds checking.  Keep not doing any bounds
checking or conversions for upper limits since nonstandard large
delays are useful for testing.

The inaccuracies are dependent on HZ and the timeout implementation.
With the old timeout implementation and HZ = 1000, 200.0 probably
worked better to emulate 250.34 than 250.34 itself.  HZ = 100 gives
roundoff errors that accidentally reduce the inaaccuracies, and
event timers reduce the inaccuracies even more, so 200.0 was giving
more like itself (perhaps 215.15 on average but sometimes close to
10 msec repeat which is noticebly too fast).  This commit makes 0.0
noticeably too slow, like 250.34 always was.

For 'make <directory>' hook into the all_subdir_<directory> targets.

This fixes parallel build issues when trying to depend on ${SUBDIR}.  An
example of this in share/i18n/csmapper/Makefile where mapper.dir depends
on ${SUBDIR} having been traversed and built already.  Before this
change running make in that directory would build the subdirectories
twice.  This led to obscure build races.  While reworking that build
may be possible, the framework should not so easily allow creating such
problems.

Now depending on <directory> will properly redirect to the
all_subdir_<directory> target rather than invoking the inline shell.

This also makes 'make -jX <directory>' now respect any
SUBDIR_DEPEND_<directory> statements when SUBDIR_PARALLEL is defined.
This is not entirely intended and may be changed later.

Stop using _SUBDIR internally for non-SUBDIR_PARALLEL builds.

This is unifying more of the logic.  Rather than create targets such
as 'all: all_subdir_foo' when using SUBDIR_PARALLEL and using
'all: _SUBDIR' when not using SUBDIR_PARALLEL, always use the
expanded out <target>_subdir_<directory> pattern.  When not using
SUBDIR_PARALLEL, have each directory-target depend on the previously
defined targets as to respect the *order* of SUBDIR.

Using 'make -N' now prints all directory traversals individually rather
than using a loop, since a loop is no longer used to traverse.

This is part of an effort to cleanup handling of some edge cases
involving 'make <directory>' and making it simpler in the sense
that the pattern used to build is the same for all modes.
