c81c59299b Add a f_vnode field to struct file.
Several of the subtypes have an associated vnode which is used for
stuff like the f*() functions.

By giving the vnode a speparate field, a number of checks for the specific
subtype can be replaced simply with a check for f_vnode != NULL, and
we can later free f_data up to subtype specific use.

At this point in time, f_data still points to the vnode, so any code I
might have overlooked will still work.

768b08c167 When DDB is active, always send printf() output directly to the
console, even if there is a TIOCCONS console tty. We were already
doing this after a panic, but it's also useful when entering DDB
for some other reason too.

65000a220a Use a new message buffer `consmsgbuf' to forward messages to a
TIOCCONS console (e.g. xconsole) via a timeout routine instead of
calling into the tty code directly from printf(). This fixes a
number of cases where calling printf() at the wrong time (such as
with locks held) would cause a panic if xconsole is running.

The TIOCCONS message buffer is 8k in size by default, but this can
be changed with the kern.consmsgbuf_size sysctl. By default, messages
are checked for 5 times per second. The timer runs and the buffer
memory remains allocated only at times when a TIOCCONS console is
active.

6bb0e5cb46 Replace the code for reading and writing the kernel message buffer
with a new implementation that has a mostly reentrant "addchar"
routine, supports multiple message buffers in the kernel, and hides
the implementation details from callers.

The new code uses a kind of sequence number to represend the current
read and write positions in the buffer. This approach (suggested
mainly by bde) permits the read and write pointers to be maintained
separately, which reduces the number of atomic operations that are
required. The "mostly reentrant" above refers to the way that while
it is now always safe to have any number of concurrent writers,
readers could see the message buffer after a writer has advanced
the pointers but before it has witten the new character.

e6efd8ec43 add support for peeking at pci busses on UltraSparc systems. This prevents
data access errors when trying to read/write to non-existant PCI devices.

fix the psycho bridge to use peek for probing devices.  This no longer
fakes it if the OFW node doesn't exist (and the reg == 0).

6731c07a2f Add clarifications about the information that ntp_gettime returns.
TAI is a timescale, just like UTC.  The tai field returns the offset
between the two, and isn't really used for precision time keeping.
Explain in brief what a positive and a negative leap seconds are.  Add
some URLs to very useful web pages about time and time keeping for
more information on using this API.
