Add an API to rendezvous all active vcpus in a virtual machine. The rendezvous
can be initiated in the context of a vcpu thread or from the bhyve(8) control
process.

The first use of this functionality is to update the vlapic trigger-mode
register when the IOAPIC pin configuration is changed.

Prior to this change we would update the TMR in the virtual-APIC page at
the time of interrupt delivery. But this doesn't work with Posted Interrupts
because there is no way to program the EOI_exit_bitmap[] in the VMCS of
the target at the time of interrupt delivery.

Support defining test program metadata from the Makefiles.

Introduce a new, per-test-program TEST_METADATA.<program> variable that
contains a list of key/value paris describing metadata properties for
that test program.  These properties are later written into the
auto-generated Kyuafile when using the KYUAFILE=auto functionality.

This is to avoid having to supply hand-crafted Kyuafiles when the needs
for metadata overrides are trivial.

While doing this, and because I am documenting TEST_METADATA, take the
chance to document the TEST_INTERFACE setting as well.

Support perl-based TAP-compliant test programs.

Introduce a TAP_TESTS_PERL primitive to list test programs written in perl.
Only do this in tap.test.mk because I only expect perl-based test programs
with this interface.

This is very similar to TAP_TESTS_SH but the difference is that we record
in the Kyuafile that the test program requires a perl interpreter.  This
in turn makes Kyua mark the test as skipped if the perl package is not yet
installed, instead of mysteriously failing to run the program.

Use TAP_TESTS_PERL to register the legacy_test in bin/pax.

Redo r260586 by using the new functionality in tap.test.mk to transparently
support perl-based test programs.

As a side-effect, we get rid of an explicit path to /usr/bin/perl by
replacing it with /usr/local/bin/perl (or as defined in tap.test.mk).

This also fixes the name of the legacy_test source file because this should
have always been legacy_test.pl and not legacy_test.sh.  My mistake when
originally moving the code around without realizing that this was a perl
script.

Replace hand-crafted Kyuafiles with automatic generation.

Redo r260506 by using the new TEST_METADATA functionality of bsd.test.mk
to mark the sh(1) and test(1) tests as not supporting root.  This is to
get rid of hand-crafted Kyuafiles for these very simple cases.

libc/resolv: Use poll() instead of kqueue().

The resolver in libc creates a kqueue for watching a single file descriptor.
This can be done using poll() which should be lighter on the kernel and
reduce possible problems with rlimits (file descriptors, kqueues).

sh: Remove SIGWINCH handler and just check for resize before every read.

The SIGWINCH handler triggers breakage in libedit which is hard to fix; see
PR bin/169773.

Also, window size changes while a program is in foreground (and it rather
than sh will receive SIGWINCH) will now be picked up automatically.

Downside: it is now certain that a resize is only processed after pressing
<Enter>. If libedit is fixed, sh will most likely have to be changed also.

Add missing arch= and revision= support.
In the nested TLB fault handler, for a direct-mapped address, make
sure to clear the lower 12 bits. We're adding the translation
attributes to the physical address and non-zero bits in the first
12 bits would give us something unexpected, including invalid bit
values. Those trigger nested general protection faults.
We do not have to clear the region bits, because they are ignored
anyway, so we can replace an existing dep instruction with the one
we need.

This fixes GP faults for the swapper thread, as it's the only thread
that has a direct-mapped stack. Since the bug is in the nested TLB
fault handler, the frequency of hitting the GP is in the order of
hours/days under load.
Update xboxfb driver to actual state.
NOTE: Not tested.
