This Almquist extension was disabled long ago.
In pathname generation, components starting with '!!' were treated as
containing wildcards, causing unnecessary readdir (which could fail, causing
pathname generation to fail while it should not).
devfs_populate(). This is a prerequisite for the automatic removal of
empty directories which will be committed in the future.

Right now unionfs only allows filesystems to be mounted on top of
another if it supports whiteouts. Even though I have sent a patch to
daichi@ to let unionfs work without it, we'd better also add support for
whiteouts to tmpfs.
This patch implements .vop_whiteout and makes necessary changes to
lookup() and readdir() to take them into account. We must also make sure
that when adding or removing a file, we honour the componentname's
DOWHITEOUT and ISWHITEOUT, to prevent duplicate filenames.

datagrams with checksum value 0 when TX UDP checksum offloading is
enabled. Generating UDP checksum value 0 is RFC 768 violation.
Even though the probability of generating such UDP datagrams is
low, I don't want to see FreeBSD boxes to inject such datagrams
into network so disable UDP checksum offloading by default. Users
still override this behavior by setting a sysctl variable or loader
tunable, dev.bge.%d.forced_udpcsum.
I have no idea why this issue was not reported so far given that
bge(4) is one of the most commonly used controller on high-end
server class systems. Thanks to andre@ who passed the PR to me.

with -Os. This is not applicable to gptboot, though.

drti.o depends on libelf and this avoids linking every other drti.o
program (namely programs with USDT probes) with libelf.

Summary of changes:
* Implement a compatibility shim between Solaris libproc and our
libproc and remove several ifdefs because of this.
* Port the drti to FreeBSD.
* Implement the missing DOODAD sections
* Link with libproc and librtld_db
* Support for ustack, jstack and uregs (by sson@)
* Misc bugfixing
When writing the SUWN_dof section, we had to resort to building the ELF
file layout by "hand". This is the job of libelf, but our libelf doesn't
support this yet. When libelf is fixed, we can remove the code under
#ifdef BROKEN_LIBELF.

LK_CANRECURSE after a lock is created. Use them to implement macros that
otherwise manipulated the flags directly. Assert that the associated
lockmgr lock is exclusively locked by the current thread when manipulating
these flags to ensure the flag updates are safe. This last change required
some minor shuffling in a few filesystems to exclusively lock a brand new
vnode slightly earlier.
