735100a9f0 The kernel bcopy() is safe for overlapping regions (and always has), so
there is no use for a separate ovbcopy().

1dfc2c167f Be consistent about "static" functions: if the function is marked
static in its prototype, mark it static at the definition too.

6be8f7b39f ^U kills an entire input line in most applications,
including the default terminal canonical mode.
So let ddb(4) be no exception from this rule.

715966bf8a 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.)

78fb7c3b79 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.

0f54a3a55f 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.

67ba7220fd A better fix for the ddb command history buffer problem; use a static
buffer instead of trying to use malloc() in the input routine.

cfad384768 Don't try to do anything with the input history if MALLOC() for the buffer
failed.

This broke early debugging.

2819c5d8c9 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...

66e9a34c96 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.

808a36ef65 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.

e1b78916a4 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.

08f9d454e0 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.

ed3ff9247c 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.

f9fc827448 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.

07e1c7f69d 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

71b67e5a56 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.
