With r284861, UMA zones use the trash ctor and dtor by default. This is
incompatible with memguard, which frees the backing page when the item
is freed. Modify the UMA debug functions to be no-ops if the item was
allocated from memguard. This also fixes constructors such as
mb_ctor_pack(), which invokes the trash ctor in addition to performing
some initialization.

This is a temporarily least intrusive crutch to get certain panicing systems

Add text to thr_exit(2) and thr_new(2) discouraging their use in
applications since calling these in a process with libthr loaded will
confuse libthr and is likely to cause hangs or crashes.
The thr_kill2(2) call is not used by libthr and may be useful in special
applications.
The other calls can be used in applications but it should not be necessary.
For FreeBSD 12, I'm considering updating setgrent() to have a function
prototype that conforms to POSIX. FreeBSD seems to be the only operating
system that lets setgrent() return an integer. It's also inconsistent
with setpwent().
It looks like our libcasper depends on setgrent() returning an integer.
Get rid of that.

The 'CONFS' entries in share/mk/bsd.confs.mk explicitly check
for the 'installconfig', but does not behave properly with the
'distribute' target.
This seems to be related to the previously-reported issues
with files within /etc in the past.

Inline version of primitives do an atomic op and if it fails they fallback to
actual primitives, which immediately retry the atomic op.
The obvious optimisation is to check if the lock is free and only then proceed
to do an atomic op.

Files listed in 'CONFS' are not properly included in new

do not fully understand.
This reverts the change excluding /etc/ppp/ppp.conf from
a new installation. /etc/dma/dma.conf is also affected,
but requires a different solution, still being investigated.

Do not set HWRTSEN bit when CTS-to-self is used; CTS2SELF bit triggers
CTS frame transmission by itself (and it does not work when HWRTSEN bit

If tzsetup UTC is run then it successfully configured the system for UTC
including installing /etc/localtime however if the user ran just tzsetup
for interactive configuration and select UTC no /etc/localtime was installed
which resulted in failures for utilities which require said file.
Change set_zone_utc to call install_zoneinfo("UTC") to ensure that
/etc/localtime is created for interactive UTC selection.
Users who have previously run tzsetup in interactive mode and select UTC
can install the missing /etc/localtime by running tzsetup -r.
Also correct static miss-match for set_zone_utc.

Receive all beacons in HOSTAP mode; they will give more information about

This simplifies setting an initial interrupt moderation value, and
avoids most calls to evx_ev_qmoderate from contexts where MCDI is

Thus remove the VIMAGE conditional field from the domain(9) protosw

This also allows us to change some order and to make the teardown functions

It seems that all versions of POSIX that I could find require that

there, move these typedefs closer to the top of the header file, right
after the includes, which we do in most other header files.
