35e61cbd71 Add a new mechanism, cndbctl(), to tell the console driver that
ddb is entered.  Don't refer to `in_Debugger' to see if we
are in the debugger.  (The variable used to be static in Debugger()
and wasn't updated if ddb is entered via traps and panic anyway.)

- Don't refer to `in_Debugger'.
- Add `db_active' to i386/i386/db_interface.d (as in
  alpha/alpha/db_interface.c).
- Remove cnpollc() stub from ddb/db_input.c.
- Add the dbctl function to syscons, pcvt, and sio. (The function for
  pcvt and sio is noop at the moment.)

Jointly developed by: bde and me

(The final version was tweaked by me and not reviewed by bde.  Thus,
if there is any error in this commit, that is entirely of mine, not
his.)

ce9edcf5b5 Merge the cons.c and cons.h to the best of my ability. alpha may or
may not compile, I can't test it.

de22efc974 The following patch will remove a hack introduced in
/sys/ddb/db_input.c rev 1.19 to recognize syscons's cursor keycodes.
It is unnecessary now that scgetc() in syscons returns the escape
sequence for the cursor keys rather than their raw, internal key
codes.

d4060a8751 Some fixes from John Hood:
1) Fix the initialization of malloc structure that changed
		due to perf opt.
	2) Remove unneeded include.
	3) An initialization assert added to malloc.

d984ae1e05 A better fix for the ddb command history buffer problem; use a static
buffer instead of trying to use malloc() in the input routine.

e7c818b53b Don't try to do anything with the input history if MALLOC() for the buffer
failed.

This broke early debugging.

ce8a015412 Minor hack to also allow for syscons's "interesting" arrow keys.
I'm using "#if __i386__ && __FreeBSD__" to check for a ``potentially
syscons-relevant environment''.  Hope that's ok...

eae6ab5e98 Everyone's favorite, i think: make DDB understand the arrow keys for the
basic cursor movements.  Assumes ANSI/DEC tty, but you can still resort
to plain emacs ^p/^n etc anyway.

6875d25465 Back out part 1 of the MCFH that changed $Id$ to $FreeBSD$. We are not

1130b656e5 Make the long-awaited change from $Id$ to $FreeBSD$
This will make a number of things easier in the future, as well as (finally!)
avoiding the Id-smashing problem which has plagued developers for so long.

Boy, I'm glad we're not using sup anymore.  This update would have been
insane otherwise.

75680b05c6 if there is no console, cngetc should act like getc and return -1
make callers aware of this in those cases where it can occur.

b463077353 Finally implement a simple commandline history in DDB.
Emacs-style line editing has already been there (did anybody ever
notice this? :), so i `only' had to add ^P and ^N.  The approach is
fairly minimalistic, with the advantage of keeping the bloat as small
as 864 bytes of .text and 16 bytes of .bss, plus 10*120 bytes
malloc'ed history buffer at the first use.

058284fceb Completed function declarations and/or added prototypes and/or #includes
to get the prototypes.

Changed some `int's to `boolean_t's.  boolean_t's are ints so they are
hard to distinguish from ints.

Converted function headers to old-style.  ddb is written in K&R1 C
except where we broke it.

f23b4c91c4 Fix up some sloppy coding practices:
- Delete redundant declarations.
- Add -Wredundant-declarations to Makefile.i386 so they don't come back.
- Delete sloppy COMMON-style declarations of uninitialized data in
  header files.
- Add a few prototypes.
- Clean up warnings resulting from the above.

NB: ioconf.c will still generate a redundant-declaration warning, which
is unavoidable unless somebody volunteers to make `config' smarter.

f540b1065a Change all #includes to follow the current Berkeley style. Some of these
``changes'' are actually not changes at all, but CVS sometimes has trouble
telling the difference.

This also includes support for second-directory compiles.  This is not
quite complete yet, as `config' doesn't yet do the right thing.  You can
still make it work trivially, however, by doing the following:

rm /sys/compile
mkdir /usr/obj/sys/compile
ln -s M-. /sys/compile
cd /sys/i386/conf
config MYKERNEL
cd ../../compile/MYKERNEL
ln -s /sys @
rm machine
ln -s @/i386/include machine
make depend
make

aaf08d94ca Make everything compile with -Wtraditional. Make it easier to distribute
a binary link-kit.  Make all non-optional options (pagers, procfs) standard,
and update LINT to reflect new symtab requirements.

NB: -Wtraditional will henceforth be forgotten.  This editing pass was
primarily intended to detect any constructions where the old code might
have been relying on traditional C semantics or syntax.  These were all
fixed, and the result of fixing some of them means that -Wall is now a
realistic possibility within a few weeks.
