completely full, we'd not complete any of the mbufs due to the fence
post error (this creates a large leak). When this is fixed, we still
leak, but at a much smaller rate due to a race between ateintr and
atestart_locked as well as an asymmetry where atestart_locked is
called from elsewhere.  Ensure that we free in-flight packets that
have completed there as well. Also remove needless check for NULL on
mb, checked earlier in the loop and simplify a redundant if.

This change is a proof of concept on how to easily integrate existing
tests from the tools/regression/ hierarchy into the /usr/tests/ test
suite and on how to adapt them to the new layout for src.

To achieve these goals, this change:

- Moves tests from tools/regression/bin/<tool>/ to bin/<tool>/tests/.
- Renames the previous regress.sh files to legacy_test.sh.
- Adds Makefiles to build and install the tests and all their supporting
  data files into /usr/tests/bin/.
- Plugs the legacy_test test programs into the test suite using the new
  TAP backend for Kyua (appearing in 0.8) so that the code of the test
  programs does not have to change.
- Registers the new directories in the BSD.test.dist mtree file.

This change fixes some cases where bsd.progs.mk would fail to handle
directories with SCRIPTS but no PROGS.  In particular, "install" did
not handle such scripts nor dependent files when bsd.subdir.mk was
added to the mix.

This is "make tinderbox" clean.

This file provides support to build test programs that comply with the
Test Anything Protocol.  Its main goal is to support the painless
integration of existing tests from tools/regression/ into the Kyua-based
test suite.

When the guest is bringing up the APs in the x2APIC mode a write to the
ICR register will now trigger a return to userspace with an exitcode of
VM_EXITCODE_SPINUP_AP. This gets SMP guests working again with x2APIC.

Change the vlapic timer lock to be a spinlock because the vlapic can be
accessed from within a critical section (vm run loop) when guest is using
x2apic mode.

sys/types.h, which includes sys/select.h, which includes
sys/_sigset.h.  The _sigset.h customizes the provided definions based
on COMPAT_43, eliminating osigset_t if symbol is not defined.  The
sys/proc.h is included after opt_compat.h and needs osigset_t.

Move opt_compat.h inclusion into the right place.

the excess code in g_io_check(), bio_resid is also truncated by
g_io_deliver().  As result, bufdonebio() assigns truncated value to
the buffer b_resid field.

Use the residual bio_completed to calculate buffer b_resid from
b_bcount in bufdonebio(), instead of bio_resid, calculated from
bio_length in g_io_deliver().

The issue is seemingly caused by the code rearrange into g_io_check(),
which is not present in stable/10.  The change still looks as the
useful change to have in 10 nevertheless.

the bio is unmapped, so we must map the bio pages into pbuf.  This
works around the geom classes which do not follow the MAXPHYS limit on
the i/o size, since such classes do not know about unmapped bios
either.

Intel manual says: "If a transition is already in progress, transition to
a new value will subsequently take effect. Reads of IA32_PERF_CTL determine
the last targeted operating point."  So seems it should be fine to just
trigger wanted transition and go.  Linux does the same.

by remote_recv_thread, which lead to crashes like below:

Taking the request back was not necessary (it would properly be
processed by the remote_recv_thread) and only complicated things.

indication when a request can be moved to done queue, but also for
detecting the current state of memsync request.

This approach has problems, e.g. leaking a request if memsynk ack from
the secondary failed, or racy usage of write_complete, which should be
called only once per write request, but for memsync can be entered by
local_send_thread and ggate_send_thread simultaneously.

So the following approach is implemented instead:

1) Use hio_countdown only for counting components we waiting to
   complete, i.e. initially it is always 2 for any replication mode.

2) To distinguish between "memsync ack" and "memsync fin" responses
   from the secondary, add and use hio_memsyncacked field.

3) write_complete() in component threads is called only before
   releasing hio_countdown (i.e. before the hio may be returned to the
   done queue).

4) Add and use hio_writecount refcounter to detect when
   write_complete() can be called in memsync case.
