LOCKDEBUG enhancements for non-MP:
...
keep a list of locked locks.
use this to print where the lock was locked
when we either go to sleep with a lock held
or try to free a locked lock.

Add options DDB_FROMCONSOLE and sysctl ddb.fromconsole, analagous to
...
DDB_ONPANIC. Lets user ignore breaks but enter DDB on panic. Intended
for machines where debug on panic is useful, but DDB entry is not,
(public-access console, or terminal-servers which send spurious breaks)
Add new ddb hook, console_debugger(), which decides whether or not to
ignore console ddb requests. Console drivers should be updated to call
console_debugger(), not Debugger(), in response to serial-console
break or ddb keyboard sequence.

Several things:
...
* Change the usage of B_DONE so that it is only set when a buffer is in sync
with the data on disk.
* If a buffer is being waited for, don't put it on the age queue.
* Make sure to clear B_DONE when pages are stolen from a buffer.
* Make sure to clear B_CACHE after each use.
* If we find a buffer for the block we want with valid data, but it is too
small, panic. (This isn't supposed to happen.)

Substantial signal handling changes:
...
* Increase the size of sigset_t to accomodate 128 signals -- adding new
versions of sys_setprocmask(), sys_sigaction(), sys_sigpending() and
sys_sigsuspend() to handle the changed arguments.
* Abstract the guts of sys_sigaltstack(), sys_setprocmask(), sys_sigaction(),
sys_sigpending() and sys_sigsuspend() into separate functions, and call them
from all the emulations rather than hard-coding everything. (Avoids uses
the stackgap crap for these system calls.)
* Add a new flag (p_checksig) to indicate that a process may have signals
pending and userret() needs to do the full (slow) check.
* Eliminate SAS_ALTSTACK; it's exactly the inverse of SS_DISABLE.
* Correct emulation bugs with restoring SS_ONSTACK.
* Make the signal mask in the sigcontext always use the emulated mask format.
* Store signals internally in sigaction structures, rather than maintaining a
bunch of little sigsets for each SA_* bit.
* Keep track of where we put the signal trampoline, rather than figuring it out
in *_sendsig().
* Issue a warning when a non-emulated sigaction bit is observed.
* Add missing emulated signals, and a native SIGPWR (currently not used).
* Implement the `not reset when caught' semantics for relevant signals.
Note: Only code touched by the i386 port has been modified. Other ports and
emulations need to be updated.

When checking for overflow in the residual count, test against SSIZE_MAX.
...
The read/write system calls return ssize_t because -1 is used to indicate
error, therefore the transfer size MUST be limited to SSIZE_MAX, otherwise
garbage can be returned to the user.
There is NO change from existing behavior here, only a more precise
definition of that the semantics are, except in the Alpha case, where
the full SSIZE_MAX transfer size can now be realized (ssize_t is 64-bit
on the Alpha).

A few small changes to how pool pages are allocated/freed:
...
- If either an alloc or release function is provided, make sure both are
provided, otherwise panic, as this is a fatal error.
- If using the default allocator, default the pool pagesz to PAGE_SIZE,
since that is the granularity of the default allocator's mechanism.
- In the default allocator, use new functions:
uvm_km_alloc_poolpage()/uvm_km_free_poolpage(), or
kmem_alloc_poolpage()/kmem_free_poolpage()
rather than doing it here. These functions may use pmap hooks to
provide alternate methods of mapping pool pages.

Implement passing credentials as ancillary data on Unix domain sockets,

similar to BSD/OS's:
- Creds are available with first data on SOCK_STREAM, and with every datagram
on SOCK_DGRAM.
- It is not possible to forge credentials.
Different in that:
- Different credential data structure (ours does not rely on the format
of internal kernel data structures, and does not pass the login name).
- We can pass creds and file descriptors at the same time (this does not
work in BSD/OS).

From 4.4BSD-Lite2 (noted by Frank van der Linden):
...
so_linger is used as an argument to tsleep(), so was stuffed with
clockticks for the TCP linger time. However, so_linger is set directly from
l_linger if the linger time is specified, and l_linger is seconds (although
this is not currently documented anywhere). Fix this to set the TCP
linger time in seconds, and multiply so_linger by hz when tsleep() is
called to actually perform the linger.

import chris torek's vfprintf() from libc [renamed to kprintf and all
...
floating point stuff removed].
the new kprintf replaces the 3 different (and buggy) versions of
printf that were in the kernel before (kprintf, sprintf, and db_printf),
thus reducing duplicated code by 2/3's. this fixes (or adds) several
printf formats. examples:
%#x - previously only supported by db_printf [not printf/sprintf]
%8.8s - printf would print "000chuck" for "chuck" before
%5p - printf would print "0x 1" for value 1 before
XXX: new kprintf still supports several non-standard '%' formats that
are supposed to eventually be removed:
%: - passes an additional format string and argument list recursively
%b - used to decode error registers
%r - int, but print in radix "db_radix" [DDB only]
%z - 'signed hex' [DDB only]
%n - unsigned int, but print in radix "db_radix" [DDB only]
note that DDB's "%n" conflicts with standard "%n" which takes the
number of characters written so far and stores it into the integer
indicated by the "int *" pointer arg. yuck!
while here, add comments for each function explaining what it is
supposed to do.
