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. :-/

76e2642ce4 subr_prf.c used to provide an exported function kprintf(), but only had 
a private declaration for it.  Declare the function publically instead.

b5e8ce9f12 Add and move declarations to fix all of the warnings from `gcc -Wimplicit' 
(except in netccitt, netiso and netns) and most of the warnings from
`gcc -Wnested-externs'.  Fix all the bugs found.  There were no serious
ones.

2336b9d7d7 Print "(null)" instead of "<null>" for NULL string args for consistency 
with the libc and ddb printf's.

Print "(fmt null)\n" for NULL formats.

8f5067ba28 Make printf() a bit more robust and allow NULL strings (print them as 
"<null>"). It bad to have diagnostic printfs cause panics when they are
trying to tell you about another problem.

797f2d22f0 All of this is cosmetic. prototypes, #includes, printfs and so on. Makes 
GCC a lot more silent.

12d17f6512 Added a %p to printf & friends, same thing as 0x%08x but more with the 
potiential to make a warning from gcc more useful.

8a129caed5 1) Changed ddb into a option rather than a pseudo-device (use options DDB 
in your kernel config now).
2) Added ps ddb function from 1.1.5. Cleaned it up a bit and moved into its
   own file.
3) Added \r handing in db_printf.
4) Added missing memory usage stats to statclock().
5) Added dummy function to pseudo_set so it will be emitted if there
   are no other pseudo declarations.

0e42760866 Made the kernel compile cleanly with gcc 2.6.0. Thanks go to Bruce 
Evans for suggesting a method to detect various versions of gcc.
