When cross-compiling, the wrong architecture was being embedded in the
libclang_rt binary filenames. It should be based on TARGET_ARCH (target), not
MACHINE_ARCH (host).
This is a draft commit against my project branch. Will fix on ^/head soon.

Add GCNOS{GRP,MODE,OWN} for parity with FILES{GRP,MODE,OWN}. The defaults are
based on BIN{GRP,MODE,OWN}.
GCNOSDIRMODE is added, strictly for configurability, if need be.
Try to install them instead of the .gcda's, since the .gcda's likely won't exist.
TODO: verify that installworld does indeed do the right thing.
Ref: gcc(1) -ftest-coverage description; --coverage (option in use) is an alias
for -fprofile-arcs -ftest-coverage
files. This is a follow up commit to r324721, which added sysrc(8) to
the SEE ALSO list.

Now that OBJS has grown an OBJS_SRCS_FILTER variable, use this variable
in the computation of BCOBJS and LLOBJS too. Also move BCOBJS and LLOBJS
computation to be next to the OBJS computation: this should both make
the parallel structure clearer and serve to remind people changing OBJS
that parallel changes are required in BCOBJS and LLOBJS.
A side effect of this change is that BCOBJS and LLOBJS will be available
even when LLVM_LINK has not been defined, but that seems like a positive
change: there's no reason we can't ask "what bitcode files would you
generate" just because we can't link those files together into a
complete bitcode representation of a binary or library.

The build rule describing how to create ${PROG_FULL}.{bc,ll} is only
dependent on LLVM_LINK being defined, not on MK_DEBUG_FILES being "yes".
Move the addition of ${PROG_FULL}.{bc,ll} out of the conditional block
under `.if ${MK_DEBUG_FILES} != "no"` and up next to where the build
rules for ${PROG_FULL}.{bc,ll} are defined.

We previously taught the build system how to create files like libfoo.bc,
but neglected to teach it about cleaning such files up. Rectify this now.

Previously before you could call unrhdr_delete you needed to
individually free every allocated unit. It is useful to be able to tear
down the unr without having to go through this process, as it is
significantly faster than freeing the individual units.

All of these arguments are stored in m_ext, so there is no reason
to pass them in the argument list. Not all functions need the second
argument, some don't even need the first one. The second argument
lives in next cache line, so not dereferencing it is a performance
gain. This was discovered in sendfile(2), which will be covered by
next commits.
The second goal of this commit is to bring even more flexibility
to m_ext mbufs, allowing to create more fields in m_ext, opaque to
the generic mbuf code, and potentially set and dereferenced by
subsystems.

This is being done for reasons parallel to MK_TESTS_SUPPORT's addition in
^/head@r273449
Unlike ^/head@r273449 though, we do want binaries to be built with coverage
support in the libraries phase, but not in the cross-tools phase.
When the EVENTHANDLER(9) subsystem was created, it was a documented feature
that an eventhandler callback function could safely deregister itself. In
r200652 that feature was inadvertantly broken by adding drain-wait logic to
eventhandler_deregister(), so that it would be safe to unload a module upon
return from deregistering its event handlers.
There are now 145 callers of EVENTHANDLER_DEREGISTER(), and it's likely many
of them are depending on the drain-wait logic that has been in place for 8
years. So instead of creating a separate eventhandler_drain() and adding it
to some or all of those 145 call sites, this creates a separate
eventhandler_drain_nowait() function for the specific purpose of
deregistering a callback from within the running callback.

If they are still needed, you can find them in the net/bsdrcmds port.
This was proposed June, 20th and approved by various committers [1].
They have been marked as deprecated on CURRENT in r320644 [2] on July, 4th.
Both stable/11 and release/11.1 contain the deprecation notice (thanks to
allanjude@).
Note that ruptime(1)/rwho(1)/rwhod(8) were initially thought to be part of
rcmds but this was a mistake and those are therefore NOT removed.

Make armv7 as a new MACHINE_ARCH.
Copy all the places we do armv6 and add armv7 as basically an
alias. clang appears to generate code for armv7 by default. armv7 hard
float isn't supported by the the in-tree gcc, so it hasn't been
updated to have a new default.
Support armv7 as a new valid MACHINE_ARCH (and by extension
TARGET_ARCH).
Add armv7 to the universe build.

The logic wasn't using a filtered version of SRCS -- it was using the
unfiltered version. This was causing some hilarity with unnecessary
dependencies, like headers and the like in lib/libc/... .
Also use .pico with bsd.lib.mk, not .o -- .o doesn't use SHARED_C*FLAGS,
which doesn't contain _COV_FLAG, which means that the .gcda's would have
relied on objects that didn't build them as a side-effect.
