fa38c73642 Remove old BSD-style entries from /etc/ttys and increase pts(4) to 512.
Because we now use pts(4)-style PTY's exclusively, there is no use for
these entries in /etc/ttys. Right now the pts(4) entries only go from 0
to 255. Because we're going to touch these files anyway, increase the
number to 511.

9888af9c4e Remove clkbrd(4) as a separate device and compile it solely based
on the presence of fhc(4) instead; we by far don't support all of
the functionality provide by the clock board but in general it's
an integral part of FireHose-based systems which shouldn't be
possible to omit.

c06f087ccb Cache the cred locally in _syncache_add() while holding the locks, so
we can be sure that it's valid.
In case we abort early free it again else put it into the syncache.

We need the cred in the syncache to be able to restrict what will be
exportet by the sysctl helper function syncache_pcblist() (to netstat)
within jails.

ukbd(4) does and that emulation was enabled by default, all three of

ce570f82cc Remove unused tty_gone() checks inside ttyoutq_read_uio().
When my earlier MPSAFE TTY prototypes still implemented line
disciplines, we needed a mechanism to abort read()'s on PTY master
devices when inside the line discipline. Because this is no longer the
case, these checks have become unneeded.

f8f8c9f0d6 Make stty(1) use tab0 and tab3 to handle tab completion.
After the MPSAFE TTY import, we have support for the TAB0 and TAB3 flags
to handle tab expansion, while we only used to support OXTABS. Switch
stty(1) to use tab0 and tab3 to print whether tab expansion is turned on
or off. Implement the oxtabs and tabs switches by setting the
appropriate TABx value.

Even though POSIX only lists this as being XSI, we'd better follow it.

ad86a65e32 Adjust the handling the various timer frequencies when using the lapic
timer.  Previously, the various divisors were fixed which meant that while
it gave somewhat reasonable stathz, etc. at hz=1000, it went off the rails
with any other hz value.  With these changes, we now pick a lapic timer hz
based on the value of hz.  If hz is >= 1500, then the lapic timer runs at
hz.  If 1500 hz >= 750, we run the lapic timer at hz * 2.  If hz < 750, we
run at hz * 4.  We compute a divider at runtime to make stathz run as close
to 128 as we can since stathz really wants to be run at something close to
that frequency.  Profiling just runs on every clock tick.  So some examples:

With hz = 100, the lapic timer now runs at 400 instead of 2000.  stathz
will be 133, and profhz = 400.  With hz = 1000 (default), the lapic timer
is still at 2000 (as it is now), stathz is at 133 (as it is now), and
profhz will be 2000 (previously 666).

0f0a7c27c5 Fix two small bugs in tcsetattr().
- According to POSIX, tcsetattr() must not fail when any of the bits in
  the structure are unsupported, but it must leave the unsupported flags
  alone.

- The CIGNORE flag (set by TCSASOFT, extension) was not cleared from
  c_cflag, which means using it would cause it to be applied during its
  entire lifespan. Eventually make sure we clear the flag.

I don't really like CIGNORE, but I think we must keep it alive right
now. With our new TTY layer, we don't actually need this mechanism,
because if you leave c_cflag, c_ispeed and c_ospeed alone, we won't make
a call into the device driver anyway.

6137be4386 Fix pts(4) error codes when slave device is closed.
Unlike pre-MPSAFE TTY, the pts(4) driver always returned ENXIO when a
read() or write() was performed on a pseudo-terminal master device when
the slave device was not opened. The old implementation had different
semantics:

- When the slave device had not been opened yet, read() and write() just
  blocked.
- When the slave device had been closed, a read() call would return 0
  bytes length.
- When the slave device had been closed, a write() call would return
  EIO.

Change the new implementation to return 0 and EIO as well. We don't
implement the first rule, but I suspect this is not needed, because
routines like openpty() also open the slave device node. posix_openpt()
users also do similar things.

d320e05ca5 Extend the support for PCI-e memory mapped configuration space access:
- Rename pciereg_cfgopen() to pcie_cfgregopen() and expose it to the
  rest of the kernel.  It now also accepts parameters via function
  arguments rather than global variables.
- Add a notion of minimum and maximum bus numbers and reject requests for
  an out of range bus.
- Add more range checks on slot/func/reg/bytes parameters to the cfg reg
  read/write routines.  Don't panic on any invalid parameters, just fail
  the request (writes do nothing, reads return -1).  This matches the
  behavior of the other cfg mechanisms.
- Port the memory mapped configuration space access to amd64.  On amd64
  we simply use the direct map (via pmap_mapdev()) for the memory mapped
  window.
- During acpi_attach() just after loading the ACPI tables, check for a
  MCFG table.  If it exists, call pciereg_cfgopen() on each subtable
  (memory mapped window).  For now we only support windows for domain 0
  that start with bus 0.  This removes the need for more chipset-specific
  quirks in the MD code.
- Remove the chipset-specific quirks for the Intel 5000P/V/Z chipsets
  since these machines should all have MCFG tables via ACPI.
- Updated pci_cfgregopen() to DTRT if ACPI had invoked pcie_cfgregopen()
  earlier.
