Integrate the tests from libxo into the FreeBSD test suite
The functional_test.sh harness for each test subdir was inspired
by the version in bin/sh/tests/functional_test.sh
Some gymnastics were required to deal with implicit rules for
.c / .o -> .out as the suffix transformation rules were
incorrectly trying to create the test outputs from some of the
source files
Pull the latest headers for Xen which allow us to add support for ARM and
use new features in FreeBSD.
This is a verbatim copy of the xen/include/public so every headers which
don't exits anymore in the Xen repositories have been dropped.
Note the interface version hasn't been bumped, it will be done in a
follow-up. Although, it requires fix in the code to get it compiled:
- sys/xen/xen_intr.h: evtchn_port_t is already defined in the headers so
drop it.
- {amd64,i386}/include/intr_machdep.h: NR_EVENT_CHANNELS now depends on
xen/interface/event_channel.h, so include it.
- {amd64,i386}/{amd64,i386}/support.S: It's not neccessary to include
machine/intr_machdep.h. This is also fixing build compilation with the
new headers.
- dev/xen/blkfront/blkfront.c: The typedef for blkif_request_segmenthas
been dropped. So directly use struct blkif_request_segment
Finally, modify xen/interface/xen-compat.h to throw a preprocessing error if
__XEN_INTERFACE_VERSION__ is not set. This is allow us to catch any file
where xen/xen-os.h is not correctly included.

Reallocate a maxlen-long buffer only when the current maxlen is
shorter than the required length. Note that it rarely happens
because maxlen is almost always 128 which covers struct sockaddr_storage.

Exploit r288122 to address a cosmetic issue. Pages belonging to either
the kernel or kmem object can't be paged out. Since they can't be paged
out, they are never enqueued in a paging queue. Nonetheless, passing
PQ_INACTIVE to vm_page_unwire() in kmem_unback() creates the appearance
that these pages are being enqueued in the inactive queue. As of r288122,
we can avoid giving this false impression by passing PQ_NONE.

Previous versions of bsd.own.mk included bsd.compiler.mk
only when _WITHOUT_SRCCONF wasn't defined. Restore this
behavior because bsd.ports.mk depends on this in subtle
ways. The compat include of bsd.compiler.mk should
be removed in 12 anyway.

Start using the fact that SUBDIR.yes is added to SUBDIR
and move from the pattern of:
.if ${MK_FOO} != "no"
SUBDIR+= bar
.endif
to
SUBDIR.${MK_FOO}+= bar
since we know that MK_FOO is always either yes or no and the latter
form is easier to follow and much shorter. Various exception to this
pattern dealt with on an ah-hoc basis.

The latest version of lex requires the latest m4 to build, add a dependency
when running the build-tools stage.
The requirement is due to the -P flag used when running m4 from usr.bin/lex
Makefile to generate skel.c. With the old m4 that fails and the failure is
ignored, resulting in an empty(-ish) skel.c, which leads to later build
failures when the misconfigured new lex tool is run.
This enables building -current (and 10-stable after MFC) on a stable-8
system again.

This prevents Windows from issuing a TRUSTED_RECEIVE_DMA command.

It appears that under some circumstances, like virtualisiation, the
'rdrand' instruction may occasionally not return random numbers, in
spite of looping attempts to do so. The reusult is a KASSERT/panic.
Reluctantly accept this state-of-affairs, but make a noise about it.
if this 'noise' spams the console, it may be time to discontinue
using that source.
This is written in a general way to account for /any/ source that
might not supply random numbers when required.

Merge additional testcases and improvements to bin/ls/ls_tests from
^/user/ngie/more-tests.
- Additional testcases added:
-- ls -D
-- ls -F
-- ls -H
-- ls -L
-- ls -R
-- ls -S
-- ls -T
-- ls -b
-- ls -d
-- ls -f
-- ls -g
-- ls -h

-- ls -n
-- ls -o
-- ls -p
-- ls -q/ls -w
-- ls -r

- Socket file creation is limited to the ls -F testcase, greatly speeding up
the test process
- The ls -C testcase was made more robust by limiting the number of columns
via COLUMNS and by dynamically formulating the columns/lines.
- Add `atf_test_case` before all testcase `head` functions.
The general stack protector is known to be weak and has pretty small
coverage. While setting stack-protector-all would give better protection
it would come with a performance cost: for this reason Google's Chrome OS
team developed a new stack-protector-strong variant.
In addition to the protections offered by -fstack-protector, the new option
will guard any function that declares any type or length of local array,
even those in structs or unions. It will also protect functions that use a
local variable's address in a function argument or on the right-hand side
of an assignment.
The option was introduced in GCC-4.9, but support for it has been
back-ported to our base GCC (r286074) and is also available in clang.
The change was tested with dbench and doesn't introduce performance
regressions. An exp-run over the ports tree revealed no failures when
using the stricter stack-protector-all. Thanks to all testers involved.
Simplify if (lladdr) condition in nd6_cache_lladdr():
For case (7) (new entry) nothing has to be done except lle_event.
Invoke this event directly from "create new lle" code block.
For case (4) (existing entry, same mac) useless mac update was performed,
along with LLENTRY_RESOLVED lle_event. There was no sense in doing that,
since nothing really had changed. Simply avoid this condition instead.
Given that, condition was simplified to (3),(5) states which can be merged
with previous block.
Eliminate nd6_llinfo_settimer(). All consumers were converted to
use nd6_llinfo_settimer_locked() in r216022.
Make nd6_llinfo_settimer_locked() static: last external consumer was

drm2: a few minor fixes after r280183
* Remove obsolete drm_agp_*_memory() prototypes.
* Fix comment in drm_fops.c (outisde -> outside).
* Fix some formatting issues in drm_stub.c (spaces -> tabs).
* Add missing case statement (gen == 3) in intel_gpu_reset().
* Restore pci_enable_busmaster() call in the init path (fixes gpu hang on i945GM).
* Replace M_WAITOK with M_NOWAIT when the return value of malloc is checked (may be incorrect).
Fix condition for nd6_llinfo_getholdsrc() introduced in r287484.
Effectively it always returned NULL so SAS was always performed and
sometimes the result might have been different.
Fix state machine change accidentally introduced in r287985:
state (4) inside nd6_cache_lladdr() (existing entry got nd message
with the same lladdress) started to cause lle state transition to STALE
instead of no-action.
