c41141b002 Fixed the formatting of some tables (mainly the one produced by ps
in ddb) which I broke by changing %8[l]x to %8p.  Hacked the central
printf routine to not add an "0x" prefix for %p formats if the field
width is nonzero.  The tables are still horribly misformatted on
64-bit machines.

Use %p instead of %8p to print pointers when the field width isn't
important.

a23d65bfc8 Cast pointers to uintptr_t/intptr_t instead of to u_long/long,
respectively.  Most of the longs should probably have been
u_longs, but this changes is just to prevent warnings about
casts between pointers and integers of different sizes, not
to fix poorly chosen types.

e0c38587af Fixed (un)sign extension bugs in %+n format. -4 became
(long)(u_long)(u_int)-4 = 0x00000000fffffffc on machines with 32-bit
ints and 64-bit longs.

Restored %z format for printing signed hex.  %+x shouldn't have been
used since it is an error in userland.

Prepared to nuke %n format by cloning it to %r.  %n shouldn't have
been used because it means something completely different in
userland.  Now %+r is equivalent to ddb's original %r, and %r is
equivalent to ddb's original %n.

Ignore '+' flag in combination with unsigned formats %{o,p,u,x}.

e796e00de3 Some cleanups related to timecounters and weird ifdefs in <sys/time.h>.
Clean up (or if antipodic: down) some of the msgbuf stuff.

Use an inline function rather than a macro for timecounter delta.

Maintain process "on-cpu" time as 64 bits of microseconds to avoid
needless second rollover overhead.

Avoid calling microuptime the second time in mi_switch() if we do
not pass through _idle in cpu_switch()

This should reduce our context-switch overhead a bit, in particular
on pre-P5 and SMP systems.

WARNING:  Programs which muck about with struct proc in userland
will have to be fixed.

f82057be9e Handle "%...p" as "%#...x" instead of "0x%...x". This is a quick fix
for field widths being 2 larger than specified for "%<number>p".  Only
printing of null pointers is "wrong" now (it is actually "right", but
inconsistent with printf(3)).

a1c995b626 Last major round (Unless Bruce thinks of somthing :-) of malloc changes.
Distribute all but the most fundamental malloc types.  This time I also
remembered the trick to making things static:  Put "static" in front of
them.

791d77e0dd Get rid of two and a half printf in the kernel.
Add more features to the one remaining to handle the job:
	+	signed quantity.
	#	alternate format
	-	left padding
	*	read width as next arg.
	n	numeric in (argument specified) default radix.

Fix the DDB debugger to use these.
Use vprintf in debug routine in pcvt.

The warnings from gcc may become more wrong and  intolerable because
of this.

Warning:  I have not checked the entire source for unsupported or
changed constructs, but generally belive that there are only a few.

f53dbe9765 Convert %p to 0x%x instead of to 0x%8x. The latter gives blank padding
in the wrong place.  Blank padding in the right place or zero padding
would be inconsistent with user mode.

Put case 'p' in alphabetical order.

Implement %p in sprintf() too.  I'd like only a single, more complete
printf() core, perhaps one based on vsnprintf().

4fb0b0de3e Implement a simple hook (or hack?) to allow graphics device console
drivers to protect DDB from being invoked while the console is in
process-controlled (i.e., graphics) mode.

Implement the logic to use this hook from within pcvt.  (I'm sure
Søren will do the syscons part RSN).

I've still got one occasion where the system stalled, but my attempts
to trigger the situation artificially resulted int the expected
behaviour.  It's hard to track bugs without the console and DDB
available. :-/

in your kernel config now).

3) Added \r handing in db_printf.
4) Added missing memory usage stats to statclock().
