Shift the responsibility of allocating memory for the string duplicate
from the caller (set_option, add_typedefs_from_file) to the callee
(add_typename) as it has more knowledge about when the duplication
actually needs to occur.

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.

This is part of an effort to cleanup handling of some edge cases
involving 'make <directory>'. It also provides the targets for
other uses.

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.

This partially reverts r296702 and reworks the original check to only
look in .CURDIR. This avoids ever trying to rebuild a .src file that is
already in the source tree as an override.

Copy over amd64's cloudabi64_sysvec.c into i386 and tailor it to work.
Again, we use a system call convention similar to FreeBSD, except that
there is no support for indirect system calls (%eax == 0).
Where i386 differs from amd64 is that we have to store thread/process
entry arguments on the stack instead of using registers. We also have to
put an extra pointer on the stack for TLS (for GSBASE). Place that
pointer in the empty slot that is normally used to hold return
addresses. That seems to keep the code simple.

The previous fix was tested mainly on 3 AT keyboards with USB adaptors where
it works. 1 USB keyboard doesn't translate Alt-PrintScreen, so the software
has to do it.
Reorganize a little to share some code and to not translate the unusual usb
scan code0x8a unless an Alt modified is set. Remove redundant check of Alt
modifiers. Translation now more clearly filters out Alt-PrintScreen before
the check.
The table of errors fixed in the previous commit had many bugs. Correct
table:
K_RAW Ctl-PrintScreen: E0-2A-E0-37 -> E0-37
K_RAW Alt-PrintScreen (with 4 comb. of Ctl/Shift): 79 -> 54
K_RAW Pause/Break (with 4 comb. of Alt/Shift): E0-46 -> E1-1D-45
K_CODE PrintScreen (with 4 comb. of Ctl/Shift): 54 -> 5c
K_CODE Alt-PrintScreen (with 4 comb. of Ctl/Shift): 7e -> 54
K_CODE Pause/Break (with 8 comb. of Ctl/Alt/Shift): 6c -> 68
That is 25 of 32 shift combinations for 2 keys fixed. All 16 combinations
were broken for K_CODE and thus also for K_XLATE.

r304436 attempted to optimize the handling of incoming UDP packet by only
making an expensive call to in_broadcast() if the mbuf was marked as an
broadcast packet. Unfortunately, this cannot work in the case of point-to-
point L2 protocols like PPP, which have no notion of "broadcast".
Discussions on how to properly fix r304436 are ongoing, but in the meantime
disable the optimization to ensure that no existing network setups are broken.

is_completion_pending governs whether or not a callout will be scheduled
when new work is queued on the IOAT device. If true, a callout is
already scheduled, so we do not need a new one. If false, we schedule
one and set it true. Because resetting the hardware completed all
outstanding work but failed to clear is_completion_pending, no new
callout could be scheduled after a reset with pending work.
This resulted in a driver hang for polled-only work.
