e1db68971e Reduce size of ufs inode.
Remove redunand i_dev and i_fs pointers, which are available as
ip->i_ump->um_dev and ip->i_ump->um_fs, and reorder members by size to
reduce padding.  To compensate added derefences, the most often i_ump
access to differentiate between UFS1 and UFS2 dinode layout is
removed, by addition of the new i_flag IN_UFS2.  Overall, this
actually reduces the amount of memory dereferences.

On 64bit machine, original struct inode size is 176, reduced to 152
bytes with the change.

1d3c0fa7b2 Remove all kernel uses of pcb_psl, but keep in in the struct to
preserve the ABI and API for applications.  It was removed in the port
to amd64, but was remained as garbage giving a micro-pessimization and
spurious single-step traps on i386.

pcb_psl was intended to be used just to do a context switch of PSL_I,
but this context switch was null in most or all versions, and
mis-switching of PSL_T was done instead.

Some history:
- in 386BSD-0.0, cpu_switch() ran at splhigh() and splhigh() did too
  much interrupt disabling, so interrupts were hard-disabled across
  cpu_switch() and too many other places
- in 386BSD-0.0-patchkit through FreeBSD-4 and FreeBSD-5 before
  SMPng, splhigh() did soft interrupt masking, and cpu_switch() was
  excessively cautious and did a cli at the start and a sti at the
  end to hard-disable interrupts across the switch
- SMPng replaced the spl's and cli's by spinlocks (just sched_lock?),
  so interrupts were hard-disabled across cpu_switch() and too many
  other places again
- initial attempts to fix this intended to restore some soft
  interrupt disabling, but to support variations in this cpu_switch()
  used pushfl/popfl into pcb_psl to avoid hard-coding the assumption
  that the initial and final states have PSL_I enabled.  But the
  version with soft interrupt disabling wasn't used for long, or was
  never committed, (except I always used my different version of it
  for UP) so the pushfl/popl and pcb_psl to hold them have been doing
  less than nothing for about 14 years.

13ee8dde04 Add virtio-console support to bhyve.
Adds virtio-console device support to bhyve, allowing to create
bidirectional character streams between host and guest.

Syntax:
-s <slotnum>,virtio-console,port1=/path/to/port1.sock,anotherport=...

Maximum of 16 ports per device can be created. Every port is named
and corresponds to an Unix domain socket created by bhyve. bhyve
accepts at most one connection per port at a time.

Limitations:
- due to lack of destructors of in bhyve, sockets on the filesystem
  must be cleaned up manually after bhyve exits
- there's no way to use "console port" feature, nor the console port
  resize as of now
- emergency write is advertised, but no-op as of now

e1e554a382 Silently ignore unexpected single-step traps (except for turning
off single-stepping).  Only do this on arches (only x86 so far)
which classify single-step traps unambiguously.

This allows other parts of the kernel to be intentionally and
unintentionally sloppy about generating single-step traps.  On
x86, at least the following places were unintentionally sloppy:
- all operations that context-switched [er]flags.  Especially
  spinlock_enter()/exit() and cpu_switch().  When single-stepped,
  saving the flags leaves PSL_T set in the saved flags, so
  restoring gives a trap that is spurious if it occurs after
  single-step mode has been left.  Switching contexts away from
  a low priority thread gives especially long-lived saved copies.
- the vm86 emulation allows user mode to set PSL_T.  This was
  correct until vm86 bios call mode was unintentionally given
  access to kdb handling its single-step traps.
Now these places are intentionally sloppy, but unexpected
debugger traps still cause panics if no debugger that handles
the trap is attached when the trap is delivered.

bd20334ca0 Abort single stepping in ddb if the trap is not for single-stepping.
This is not very easy to do, since ddb didn't know when traps are
for single-stepping.  It more or less assumed that traps are either
breakpoints or single-step, but even for x86 this became inadequate
with the release of the i386 in ~1986, and FreeBSD passes it other
trap types for NMIs and panics.

On x86, teach ddb when a trap is for single stepping using the %dr6
register.  Unknown traps are now treated almost the same as breakpoints
instead of as the same as single-steps.  Previously, the classification
of breakpoints was almost correct and everything else was unknown so
had to be treated as a single-step.  Now the classification of single-
steps is precise, the classification of breakpoints is almost correct
(as before) and everything else is unknown and treated like a
breakpoint.

This fixes:
- breakpoints not set by ddb, including the main one in kdb_enter(),
  were treated as single-steps and not stopped on when stepping
  (except for the usual, simple case of a step with residual count 1).
  As special cases, kdb_enter() didn't stop for fatal traps or panics
- similarly for "hardware breakpoints".

Use a new MD macro IS_SSTEP_TRAP(type, code) to code to classify
single-steps.  This is excessively complicated for bug-for-bug and
backwards compatibilty.  Design errors apparently started in Mach
in ~1990 or perhaps in the FreeBSD interface in ~1993.  Common trap
types like single steps should have a unique MI code (like the TRAP*
codes for user SIGTRAP) so that debuggers don't need macros like
IS_SSTEP_TRAP() to decode them.  But 'type' is actually an ambiguous
MD trap number, and code was always 0 (now it is (int)%dr6 on x86).
So it was impossible to determine the trap type from the args.
Global variables had to be used.

There is already a classification macro db_pc_is_single_step(), but
this just gets in the way.  It is only used to recover from bugs in
IS_BREAKPOINT_TRAP().  On some arches, IS_BREAKPOINT_TRAP() just
duplicates the ambiguity in 'type' and misclassifies single-steps as
breakpoints.  It defaults to 'false', which is the opposite of what is
needed for bug-for-bug compatibility.

When this is cleaned up, MI classification bits should be passed in
'code'.  This could be done now for positive-logic bits, since 'code'
was always 0, but some negative logic is needed for compatibility so
a simple MI classificition is not usable yet.

After reading %dr6, clear the single-step bit in it so that the type
of the next debugger trap can be decoded.  This is a little
ddb-specific.  ddb doesn't understand the need to clear this bit and
doing it before calling kdb is easiest.  gdb would need to reverse
this to support hardware breakpoints, but it just doesn't support
them now since gdbstub doesn't support %dr*.

Fix a bug involving %dr6: when emulating a single-step trap for vm86,
set the bit for it in %dr6.  Userland debuggers need this.  ddb now
needs this for vm86 bios calls.  The bit gets copied to 'code' then
cleared again.

Fix related style bugs:
- when clearing bits for hardware breakpoints in %dr6, spell the mask
  as ~0xf on both amd64 and i386 to get the correct number of bits
  using sign extension and not need a comment about using the wrong
  mask on amd64 (amd64 traps for invalid results but clearing the
  reserved top bits didn't trap since they are 0).
- rewrite my old wrong comments about using %dr6 for ddb watchpoints.
