only once, and ordered from the bottom of the tree to the top. For
intel_gas.c, the only user of RB_AUGMENT I can find, change the
augmenting routine so that it does not climb from entry to tree root
on every call, and remove a 'tree correcting' function that can be
supplanted by proper tree augmentation.

If the bio was split into several bios going down, completion computes
bio_completed of the original bio as sum of the bio_completes of the
splits. For BIO_SETUP, bio_length means something different than the
length. it is the requested speedup amount, and is duplicated into the
splits, which is in fact reasonable, since we cannot know how the
previous activity was distributed among subordinate geoms. Obviously,
the sum of n bio_length is greater than bio_length for n > 1, which
triggers assert that bio_length >= bio_completed for e.g. geom_stripe
and geom_raid3.
Fix this by reassigning bio_completed from bio_length for completed
BIO_SPEEDED, I do not think it really mattters what we return in
bio_completed.

In order to do so we need to install the msdosfs headers to the bootstrap
sysroot and avoid includes of kernel headers that may not exist on every
host (e.g. sys/lockmgr.h). This change should allow bootstrapping of makefs
on FreeBSD 11+ as well as Linux and macOS.
We also have to avoid using the IO_SYNC macro since that may not be
available. In makefs it is only used to switch between calling
bwrite() and bdwrite() which both call the same function. Therefore we
can simply always call bwrite().
For our CheriBSD builds we always bootstrap makefs by setting
LOCAL_XTOOL_DIRS='lib/libnetbsd usr.sbin/makefs' and use the makefs binary
from the build tree to create a bootable disk image.

The PR reported a crash that occurred when a file was removed while
client(s) were actively doing lock operations on it.
Since nfsvno_getvp() will return NULL when the file does not exist,
the bug was obvious and easy to fix via this patch. It is a little
surprising that this wasn't found sooner, but I guess the above
case rarely occurs.

These should not be any functional change. While the change in
emul10kx-pcm.c looks like a real bug fix (as opposed to inconsistent
whitespace), the extra statements were not harmful.

Originally, hack.c was compiled into a shard object with just -shared
-nostdlib. This assumed that ${CC} did not require any additional
flags for ABIs, cross-building, etc.
When kern.post.mk was created in r89509 by reducing duplication in
kernel Makefile.<arch> files, the -shared flag was moved into a
HACK_EXTRA_FLAGS variable so that sparc64 could override it with
-Wl,-shared. The sparc64 hack was removed in r111650, but
HACK_EXTRA_FLAGS was left in place. Over time, we have started
support toolchains that require flags to support alternate ABIs on
MIPS and PowerPC and started (ab)using HACK_EXTRA_FLAGS to set only
those flags.
I need to fix risc-v to pass -mno-relax to the hack.c build for lld in
llvm 10, and the patches to support cross-build from non-FreeBSD hosts
need to include -target for clang in CFLAGS for hack.c. Rather than
adding more hacks into HACK_EXTRA_FLAGS, just use the full set of
CFLAGS with hack.c.

Thus by replacing NULL routines with vop_bypass we avoid a runtime check.

vdbatch_process leaves the critical section too early, openign a time
window where another thread can get scheduled and modify vd->freevnodes.
Once it the preempted thread gets back it overrides the value with 0.
Just move critical_exit to the end of the function.
This mostly eliminates the requirement that vput never unlocks the vnode
before calling VOP_INACTIVE. Note it may still be present for other
filesystems.
See r356126 for an example bug.
Note vput stopped doing early unlock in r357070 thus this change does
not affect correctness as it is.
