vpanic() uses spinlock_enter() to disable interrupts before dumping core.
However, when the scheduler is stopped and INVARIANTS is not configured,
thread_lock() does not acquire a spinlock section, while thread_unlock()
releases one. This can result in interrupts staying enabled while the
kernel dumps core, complicating post-mortem analysis of the crash.

Assert that there is no new waiters for the already terminated objects.
Old waiters should have been notified by the termination calling
vnode_pager_dealloc() (old/new are with regard of the lock acquisition
interval).
Only clear the vp->v_object for the case of already terminated object,
since other branches call vnode_pager_dealloc(), which should clear
the pointer. Assert this.

a) Combine t4_set_tcb_field and t4_set_tcb_field_rpl into a single
function. Allow callers to direct the response to any iq. Tidy up
set_ulp_mode_iscsi while there to use names from t4_tcb.h instead of
magic constants.
b) Remove all CPL handler tables from struct adapter. This reduces its
size by around 2KB. All handlers are now registered at MOD_LOAD instead
of attach or some kind of initialization/activation. The registration
functions do not need an adapter parameter any more.
c) Add per-iq handlers to deal with CPLs whose destination cannot be
determined solely from the opcode. There are 2 such CPLs in use right
now: SET_TCB_RPL and L2T_WRITE_RPL. The base driver continues to send
filter and L2T_WRITEs over the mgmtq and solicits the reply on fwq.
t4_tom (including the DDP code) now uses the port's ctrlq to send
L2T_WRITEs and SET_TCB_FIELDs and solicits the reply on an ofld_rxq.
fwq and ofld_rxq have different handlers that know what kind of tid to
expect in the reply. Update t4_write_l2e and callers to to support any
wrq/iq combination.

callout thread that can cause a kernel panic. Always do the final cleanup
in the callout thread by passing a separate callout function for that task
to callout_reset_sbt().
Protect the ref_count decrement in the callout with DN_BH_WLOCK(). All
other ref_count manipulation is protected with this lock.
There is still a tiny window between ref_count reaching zero and the end
of the callout function where it is unsafe to unload the module. Fixing
this would require the use of callout_drain(), but this can't be done
because dummynet holds a mutex and callout_drain() might sleep.
Remove the callout_pending(), callout_active(), and callout_deactivate()
calls from calculate_drop_prob(). They are not needed because this callout
uses callout_init_mtx().

Original commit message:
Initial bhyve native graphics support.
This adds emulations for a raw framebuffer device, PS2 keyboard/mouse,
XHCI USB controller and a USB tablet.
A simple VNC server is provided for keyboard/mouse input, and graphics
output.
A VGA emulation is included, but is currently disconnected until an
additional bhyve change to block out VGA memory is committed.

and UEFI f/w support by Leon Dang
- VGA, console/g, initial VNC server by tychon@
- PS2 keyboard/mouse jointly done by tychon@ and Leon Dang
- hypervisor framebuffer mem support by neel@
Tested by: Michael Dexter, in a number of revisions of this code.
With the appropriate UEFI image, FreeBSD, Windows and Linux guests can

For all locales with variants:
- if no ambiguity on the locale (only one variant) just use the regular name
- if ambiguity, pick one as default and append @<variant> to the others
respecting POSIX
As a result:
- All the 3 components locales added recently are renamed to the usual 2
components version for all but sr_RS.UTF-8
- Set sr_RS.UTF-8 to the cyrillic variant
- Add sr_RS.UTF-8@latin
- Remove the symlinks aliases they were created to represent the 2 components
version as aliasas and are now useless
- Update the OptionalObsoleteFiles.inc and ObsoleteFiles.inc to reflect those

In issignal(), when handling stopping signal for thread in
TD_SBDRY_INTR state, do not stop, this is wrong and fires assert.
This is yet another place where execution should be forced out of
SBDRY-protected region. For such case, return -1 from issignal() and
translate it to corresponding error code in sleepq_catch_signals().
Assert that other consumers of cursig() are not affected by the new

Split initializzation an teardown into module (global state) and VNET
(per virtual network stack) parts. Virtualise global state, which is
not "const".
Cleanup eventhandlers, so that we can make use of the passed in argument
to get the vnet state from the ifp; disable the "cloner" event as it is
too early, has no state, and can fire before initialisation (see comment
in the source).
Handle the dynamic sysctls specially. The problem is that "ipmain"
is the virtualized struct, but the fields used for the sysctls are
hanging off memory allocated and attached to the virtualized "ipmain"
thus standard VNET macros and sysctl handling do not work.
We still say it is VNET sysctls to get the proper protection checks
in the VIMAGE case; to solve the problem of accessing the right bit
of memory hanging of each per-VNET ipmain, we use a dedicated handler
function wrapping around sysctl_ipf_int() undoing the base calculation
from kern_sysctl.c and then adding the passed-in offset into the right
struct depending on handler. A bit of a mess exposing VNET-internals
this way but the only way to keep the code without having to massively
restructure ipf internals.
