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.

996c772f58 This is the kernel Lite/2 commit. There are some requisite userland
changes, so don't expect to be able to run the kernel as-is (very well)
without the appropriate Lite/2 userland changes.

The system boots and can mount UFS filesystems.

Untested: ext2fs, msdosfs, NFS
Known problems: Incorrect Berkeley ID strings in some files.
		Mount_std mounts will not work until the getfsent
		library routine is changed.

7d350e7256 Fixed printing of small offsets. E.g., -4(%ebp) is now printed
as -0x4(%ebp) instead of as _APTD+0xffc(%ebp), and if GUPROF is
defined, 8(%ebp) is now printed as 0x8(%ebp) instead of as
GMON_PROF_HIRES+0x4(%ebp).

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.

c7c34a24a3 Attached vm ddb commands show map', show vmochk', `show object',
`show vmopag', `show page' and `show pageq'.  Moved all vm ddb stuff
to the ends of the vm source files.

Changed printf() to db_printf(), `indent' to db_indent, and iprintf()
to db_iprintf() in ddb commands.  Moved db_indent and db_iprintf()
from vm to ddb.

vm_page.c:
Don't use __pure.  Staticized.

db_output.c:
Reduced page width from 80 to 79 to inhibit double spacing for long
lines (there are still some problems if words are printed across
column 79).

6337f4efa8 Support statically attaching of ddb commands in non-ddb modules.
The details are hidden in the DB_COMMAND(cmd_name, func_name) and
DB_SHOW_COMMAND(cmd_name, func_name) macros.  DB_COMMAND() adds to
the top-level ddb command table and DB_SHOW_COMMAND adds to the
`show' subtable.  Most external commands will probably be `show'
commands with no side effects.  They should check their pointer
args more carefully than `show map' :-), or ddb should trap internal
faults better (like it does for memory accesses).

The vm ddb commands are temporarily unattached.

ddb.h:
Also declare `db_indent' and db_iprintf() which will replace vm's
`indent' and iprintf().

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.

4a32095f34 A small bit of defensive programming in case the panic is during process
exit and cleanup.  the 'ps' command assumes that there are always 'nproc'
processes on the lists and will walk off the end without checking if not,
causing ddb to trap during the 'ps' command.

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.

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.

except where we broke it.

b5d89ca8ad Load the kernel symbol table in the boot loader and not at compile time.
(Boot with the -D flag if you want symbols.)

Make it easier to extend `struct bootinfo' without losing either forwards
or backwards compatibility.

ddb_aout.c:
Get the symbol table from wherever the loader put it.
Nuke db_symtab[SYMTAB_SPACE].

boot.c:
Enable loading of symbols.  Align them on a page boundary.  Add printfs
about the symbol table sizes.
Pass the memory sizes to the kernel.
Fix initialization of `unit' (it got moved out of the loop).
Fix adding the bss size (it got moved inside an ifdef).
Initialize serial port when RB_SERIAL is toggled on.
Fix comments.
Clean up formatting of recently added code.

io.c:
Clean up formatting of recently added code.

netboot/main.c, machdep.c, wd.c:
Change names of bootinfo fields.

LINT:
Nuke SYMTAB_SPACE.
Fix comment about DODUMP.

Makefile.i386:
Nuke use of dbsym.
Exclude gcc symbols from kernel unless compiling with -g.
Remove unused macro.
Fix comments and formatting.

genassym.c:
Generate defines for some new bootinfo fields.  Change names of old ones.

locore.s:
Copy only the valid part of the `struct bootinfo' passed by the loader.
Reserve space for symbol table, if any.

machdep.c:
Check the memory sizes passed by the loader, if any.  Don't use them yet.

bootinfo.h:
Add a size field so that we can resolve some mismatches between the loader
bootinfo and the kernel boot info.  The version number is not so good for
this because of historical botches and because it's harder to maintain.
Add memory size and symbol table fields.  Change the names of everything.

Hacks to save a few bytes:

asm.S, boot.c, boot2.S:
Replace `ouraddr' by `(BOOTSEG << 4)'.

boot.c:
Don't statically initialize `loadflags' to 0.  Disable the "REDUNDANT"
code that skips the BIOS variables.  Eliminate `total'.  Combine some
more printfs.

boot.h, disk.c, io.c, table.c:
Move all statically initialzed data to table.c.

io.c:
Don't put the A20 gate bits in a variable.
