o add CFI_SUPPORT_STRATAFLASH compile option to enable support
o add new ioctls to get/set the factory and user/oem segments of the PR
and to get/set Protection Lock Register that fuses the user segment
o add #defines for bits in the status register
o update cfi_wait_ready to take an offset so it can be used to wait for
PR write completion and replace constants w/ symbolic names
Note: writing the user segment isn't correct; committing now to get review.

When we leave the console TTY constantly open, we never reset the
termios attributes. This causes output processing, echoing, etc. not to
be reset to the proper values when going into single user mode after the
system has booted. It also causes nl-to-crnl-conversion not to take
place during shutdown, which causes a `staircase effect'.
This patch adds a new TTY flag, TF_OPENED_CONS, which is set when the
TTY is opened through /dev/console. Because the flags are only used by
the kernel and the pstat(8) utility, I've decided to renumber the TTY
flags. This shouldn't be an issue, because the TTY layer is not yet part
of a stable release.

jail doesn't support. This involves a new function prison_check_af,
like prison_check_ip[46] but that checks only the family.
With this change, most of the errors generated by jailed sockets
shouldn't ever occur, at least until jails are changeable.

return zero on success and an error code otherwise. The possible errors
are EADDRNOTAVAIL if an address being checked for doesn't match the
prison, and EAFNOSUPPORT if the prison doesn't have any addresses in
that address family. For most callers of these functions, use the
returned error code instead of e.g. a hard-coded EADDRNOTAVAIL or
EINVAL.
Always include a jailed() check in these functions, where a non-jailed
cred always returns success (and makes no changes). Remove the explicit
jailed() checks that preceded many of the function calls.

Right now we only have a very small amount of drivers that use clists,
but we still allocate 50 cblocks as slush space, which allows drivers to
temporarily overcommit their storage. Most of the drivers don't allow
this anyway.
I've performed the following changes:
- We don't allocate any cblocks on startup.
- I've removed the DDB command, because it has nothing useful to print
now. You can obtain the amount of allocated blocks by running `vmstat
-m | grep clist'.
- I've removed cfreecount, which is now unused.
- The old code first tries to allocate using M_NOWAIT, followed by
M_WAITOK. This doesn't make any sense, so just remove this logic. It
seems the drivers allow us to sleep anyway.
We can even remove ccmax from clist_alloc_cblocks and c_cbmax from
struct clist, but this breaks binary compatibility.
This reduces the amount of allocated cblocks on my system from 54 to 4.

robust. With these changes fsck is now able to detect and reliably
rebuild corrupted cylinder group maps. The -D option is no longer
necessary as it has been replaced by a prompt asking whether the
corrupted cylinder group should be rebuilt and doing so when requested.
These actions are only offered and taken when running fsck in manual
mode. Corrupted cylinder groups found during preen mode cause the fsck
to fail.
Add the -r option to free up excess unused inodes. Decreasing the
number of preallocated inodes reduces the running time of future
runs of fsck and frees up space that can allocated to files. The -r
option is ignored when running in preen mode.

turbo option in addition to the mode bits; otherwise if the current
channel is a turbo mode channel we'll form an invalid media setting
and the ifmedia_set operation in vap_attach will panic.
While here use C99-style initialization for an array indexed by mode;
this makes it consistent w/ other usage and avoids breakage if we
should ever change the set of modes.
