Add the infrastructure to allow MD procctl(2) commands, and use it to
introduce amd64 PTI control and reporting. PTI mode cannot be

PTI mode for the process pmap on exec is activated iff P_MD_PTI is set.
On exec, the existing vmspace can be reused only if pti mode of the

cpu_exec_vmspace_reuse() callback for exec_new_vmspace() which can

When the pmap with pti disabled (i.e. pm_ucr3 == PMAP_NO_CR3) is
activated, tss.rsp0 was not updated. Any interrupt that happen before
next context switch would use pti trampoline stack for hardware frame
but fault and interrupt handlers are not prepared to this. Correctly
update tss.rsp0 for both PMAP_NO_CR3 and pti pmaps.
Note that this case, pti = 1 but pmap->pm_ucr3 == PMAP_NO_CR3 is not
used at the moment.

Previously the main pfsync lock and the bucket locks shared the same name.
This lead to spurious warnings from WITNESS like this:
acquiring duplicate lock of same type: "pfsync"
1st pfsync @ /usr/src/sys/netpfil/pf/if_pfsync.c:1402
2nd pfsync @ /usr/src/sys/netpfil/pf/if_pfsync.c:1429
It's perfectly okay to grab both the main pfsync lock and a bucket lock at the
same time.
We don't need different names for each bucket lock, because we should always
only acquire a single one of those at a time.

This initial integration takes googlemock/googletest release 1.8.1, integrates
the library, tests, and sample unit tests into the build.
googlemock/googletest's inclusion is optionally available via `MK_GOOGLETEST`.
`MK_GOOGLETEST` is dependent on `MK_TESTS` and is enabled by default when
built with a C++11 capable toolchain.
Google tests can be specified via the `GTESTS` variable, which, in comparison
with the other test drivers, is more simplified/streamlined, as Googletest only
supports C++ tests; not raw C or shell tests (C tests can be written in C++
using the standard embedding methods).
No dependent libraries are assumed for the tests. One must specify `gmock`,
`gmock_main`, `gtest`, or `gtest_main`, via `LIBADD` for the program.
More information about googlemock and googletest can be found on the
Googletest [project page](https://github.com/google/googletest), and the
[GoogleMock](https://github.com/google/googletest/blob/v1.8.x/googlemock/docs/Documentation.md)
and
[GoogleTest](https://github.com/google/googletest/tree/v1.8.x/googletest/docs)
docs.
These tests are originally integrated into the build as plain driver tests, but
will be natively integrated into Kyua in a later version.

`arc_reclaim_thread()` calls `arc_adjust()` after calling
`arc_kmem_reap_now()`; `arc_adjust()` signals `arc_get_data_buf()` to
indicate that we may no longer be `arc_is_overflowing()`.
The problem is, `arc_kmem_reap_now()` can take several seconds to
complete, has no impact on `arc_is_overflowing()`, but due to how the
code is structured, can impact how long the ARC will remain in the
`arc_is_overflowing()` state.
The fix is to use seperate threads to:
1. keep `arc_size` under `arc_c`, by calling `arc_adjust()`, which
improves `arc_is_overflowing()`
2. keep enough free memory in the system, by calling
`arc_kmem_reap_now()` plus `arc_shrink()`, which improves
`arc_available_memory()`.

After r345180 we need to have the appropriate vnet context set to delete an
rtnode in bridge_rtnode_destroy().
That's usually the case, but not when it's called by the STP code (through
bstp_notify_rtage()).
We have to set the vnet context in bridge_rtable_expire() just as we do in the
other STP callback bridge_state_change().

If underlying driver provides no TRIM/UNMAP support and operation fails
due to this reason, state it clearly in verbose mode (default)
instead of writing standard message that may be too cryptic for a user:
trim: ioctl(DIOCGDELETE) failed: nda0: Operation not supported
Now it would write:
trim: nda0: TRIM/UNMAP not supported by driver
But still use previous format including errno value for quiet mode.
Small candelete() function borrowed from diskinfo(8) code.
This function was committed by Alan Somers <asomers@FreeBSD.org>,
so give him some credit.

bridge_rtnode_zone still has outstanding allocations at the time of
destruction in the current model because all of the interface teardown
happens in a VNET_SYSUNINIT, -after- the MOD_UNLOAD has already been
processed. The SYSUNINIT triggers destruction of the interfaces, which then
attempts to free the memory from the zone that's already been destroyed, and
we hit a panic.
Solve this by virtualizing the uma_zone we allocate the rtnodes from to fix
the ordering. bridge_rtable_fini should also take care to flush any
remaining routes that weren't taken care of when dynamic routes were flushed
in bridge_stop.

If the spanning tree root interface is removed from the bridge we panic
on the next 'ifconfig'.
While the STP code is notified whenever a bridge member interface is
removed from the bridge it does not clear the bs_root_port. This means
bs_root_port can still point at an bridge_iflist which has been free()d.
The next access to it will panic.
Explicitly check if the interface we're removing in bstp_destroy() is
the root, and if so re-assign the roles, which clears bs_root_port.

With new pfil(9) KPI it is possible to pass a void pointer with length
instead of mbuf pointer to a packet filter. Until this commit no filters
supported that, so pfil run through a shim function pfil_fake_mbuf().
Now the ipfw(4) hook named "default-link", that is instantiated when
net.link.ether.ipfw sysctl is on, supports processing pointer/length
packets natively.
- ip_fw_args now has union for either mbuf or void *, and if flags have
non-zero length, then we use the void *.
- through ipfw_chk() we handle mem/mbuf cases differently.
- ether_header goes away from args. It is ipfw_chk() responsibility
to do parsing of Ethernet header.
- ipfw_log() now uses different bpf APIs to log packets.
Although ipfw_chk() is now capable to process pointer/length packets,
this commit adds support for the link level hook only, see
ipfw_check_frame(). Potentially the IP processing hook ipfw_check_packet()
can be improved too, but that requires more changes since the hook
supports more complex actions: NAT, divert, etc.
