4f8be175d5 Add an API to deliver message signalled interrupts to vcpus. This allows
callers treat the MSI 'addr' and 'data' fields as opaque and also lets
bhyve implement multiple destination modes: physical, flat and clustered.

cf9c3e5697 Fix a long-standing edge-case that would result in a ghosted `zroot' pool
and subsequent headaches caused by multiple pools with the same name.
Specifically, blast away any labels on the designated swap partition.
Problem was when you install to a given layout *with* swap and then turn
around and re-install the same layout *without* swap (we weren't doing a
labelclear for the swap device, so would end up with an "UNAVAIL" status
zroot pool that may only exist in the pool cache).

7cae6aab5b Improve default ZFS disk layout (tested):
+ For GPT, always provision zfs# partition after swap [for resizability]
+ For MBR, always use a boot pool to relialy place root vdevs at EOD
NB: Fixes edge-cases where MBR combination failed boot (e.g. swap-less)
+ Generalize boot pool logic so it can be used for any scheme (namely MBR)
+ Update existing comments and some whitespace fixes
+ Change some variable names to make reading/debugging the code easier
  in zfs_create_boot() (namely prepend zroot_ or bootpool_ to property)
+ Because zroot vdevs are at EOD, no longer need to calculate partsize
  (vdev consumes remaining space after allocating swap)
+ Optimize processing of disks -- no reason to loop over the disks 3-4
  separate times when we can logically use a single loop to do everything

d25257776a Add a fix for Long-standing problem with VMware. Described in below links:
https://communities.vmware.com/thread/107230
https://communities.vmware.com/docs/DOC-11677

Basically, ignore the ``function 62'' and ``function 63'' interpretations
of the left/right command key when we're in the lengthiest portion of the
installation (initiated by the `auto' module).

The net effect is that you can now (once you've started the installer from
the media) escape the VM without prematurely terminating the current action
due to spurious escape sequence.

1871769f1f tzfile.5: catch up to r204333
The stdtime sources were moved from lib/libc to contrib/tzcode, and tzfile.h
is not an installed header, so the man page refers to its location in the
source tree.

The documentation could be more clear about the internal nature of the
header, but those changes should go through upstream tzcode.

15773775f7 Properly drain the TTY when both revoke(2) and close(2) end up closing
the TTY. In such a case, ttydev_close() is called multiple times and
each time, t_revokecnt is incremented and cv_broadcast() is called for
both the t_outwait and t_inwait condition variables.
Let's say revoke(2) comes in first and gets to call tty_drain() from
ttydev_leave(). Let's say that the revoke comes from init(8) as the
result of running "shutdown -r now". Since shutdown prints various
messages to the console before announing that the machine will reboot
immediately, let's also say that the output queue is not empty and
that tty_drain() has something to do. Let's assume this all happens
on a 9600 baud serial console, so it takes a time to drain.
The shutdown command will exit(2) and as such will end up closing
stdout. Let's say this close will come in second, bump t_revokecnt
and call tty_wakeup(). This has tty_wait() return prematurely and
the next thing that will happen is that the thread doing revoke(2)
will flush the TTY. Since the drain wasn't complete, the flush will
effectively drop whatever is left in t_outq.

This change takes into account that tty_drain() will return ERESTART
due to the fact that t_revokecnt was bumped and in that case simply
call tty_drain() again. The thread in question is already performing
the close so it can safely finish draining the TTY before destroying
the TTY structure.

Now all messages from shutdown will be printed on the serial console.
