from umodem and ufoma.
With these changes, umodem kinda works for me now. It certainly gets
past the "tip" bug that I found earlier where 115200 wasn't a valid
baud rate. This was "broken" in the mpsafetty commit, but in reality,
umodem was always broken.
When I imported the MPSAFE TTY code, I added the -p flag to sh(1)'s
ulimit, but I forgot to document it in the appropriate manual page.

errata of USIII and beyond (USIII erratum #19, USIII+ erratum #1,
USIIIi erratum #1).
- Use the cheetah PA mask in {d,i}tlb_va_to_pa_sun4u() for USIII
and beyond. This is done so that these functions will still mask
the debug bits of spitfire-class CPUs once we increase TD_PA_BITS
to match the number of bits used for the PA by cheetah-class CPUs.
- Change {d,i}tlb_enter_sun4u() to also set TLB_CTX_KERNEL as the
context of the mappings entered. This is more or less cosmetic as
TLB_CTX_KERNEL is 0.
- Now that we have to distinguish between different sun4u CPUs in
the loader anyway, no longer do trial and error when reading the
portid property.

- In the current design, when a TTY decreases its baud rate, it tries to
shrink the queues. This may not always be possible, because it will
not free any blocks that are still filled with data.
Change the TTY queues to store a `quota' value as well, which means it
will not free any blocks when changing the baud rate, but when placing
blocks back into the queue. When the amount of blocks exceeds the
quota, they get freed.
It also fixes some edge cases, where TIOCSETA during read()/
write()-calls could actually make the queue a tiny bit bigger than in
normal cases.
- Don't leak blocks of memory when calling TIOCSETA when the device
driver abandons the TTY while allocating memory.
- Create ttyoutq_init() and ttyinq_init() to initialize the queues,
instead of initializing them by hand. The new TTY snoop driver also
creates an outq, so it's good to have a proper interface to do this.

stopped nor the waiting state and also no other means to check
whether the receiver is idle (see also r163774), we have no choice
than to call mii_tick(9) unconditionally even in the case of the
DC_REDUCED_MII_POLL handling as far as the RX side is concerned.
This isn't necessarily worse than checking whether RX is idle
though because unlike as with TX we're racing with the hardware,
which might receive packets any time while we poll the MII, anyway.

Option '-B none' can by used to prevent backup. Option '-B path' can be
used to backup metadata to a different file than the default, which is
/var/backups/<prov>.eli.
The 'geli init' command also prints backup file location and gives short
procedure how to restore metadata.
The 'geli setkey' command now warns that even after passphrase change or keys
update there could be version of the master key encrypted with old
keys/passphrase in the backup file.
Add regression tests to verify that new functionality works as expected.
Update other regression tests so they don't create backup files.

While merging back my changes from Perforce, it seemed I removed a
locking assertion that still applies to ttydisc_rint_poll(). Restore it,
because it may come in handy.
- Implement IMAXBEL. It turned out the IMAXBEL termios switch was marked
as supported, while it had not been implemented.
- Don't go into the high watermark when in canonical mode, no data has
been canonicalized and the input buffer is full. This caused the
terminal to lock up. This prevented users from pressing
backspace/^U/etc in such cases.
This could easily be simulated by pasting a very big amount of data in
a shell with sh(1) in canonical mode.
