KNF

Since curlwp and curproc must always be non-NULL, remove the == NULL branches.

branches: 1.24.66; 1.24.72; 1.24.74;
Replace the Mach-derived boolean_t type with the C99 bool type. A
future commit will replace use of TRUE and FALSE with true and false.

branches: 1.23.26;
merge ktrace-lwp.

branches: 1.22.4;
nuke trailing whitespace

branches: 1.21.2; 1.21.10; 1.21.12;
Add a rudimentary 'trap to kgdb' command if KGDB is defined. This allows
systems with only one serial port for console, etc., to have at least some
basic access to remote-kgdb-over-serial, even if it is a bit awkward.

Merge the nathanw_sa branch.

ANSIfy, KNF.
Make some variables and functions static when not used outside of a module.
Make variables in headers extern.
Delete the unused db_find_watchpoint() function.

add RCSIDs

branches: 1.17.2; 1.17.4;
When we hit a breakpoint in a process, print the pid of the process as
well as the command name (p_comm) of the process.

Provide some info on what db_trap_callback() is for in the code.

Move platform db_trap callback from arch/mips into ddb as suggested by
jhawk. This callback is used by platform code to manage things like
watchdogs that should be disabled while in ddb. Done as a callback
for processors such as mips that support lots of different systems.

branches: 1.14.2;
Quote "AS IS" as in the majority of Carnegy Mellon notices.

Fix a pasto in copyright text which has been procreating like rabbits..

branches: 1.12.6;
Indent to 4 space for tabs 2 and 3 like the rest of the code

Have to fix the `(int)curproc' lossage now; kernel builds die here on alpha.

BTW, KNF requires the additional, not-technically-need `!= NULL'.

Print program name when entering the debugger

DDB prototype changes.

Leave db_recover as it was on entry to avoid endless "exception in ddb"...
(Don't need to frob it at all here because db_command_loop does it.)

Clean up #includes.

Add prototypes.

New RCS ID's, take two. they're more aesthecially pleasant, and use 'NetBSD'

Try to deal with db_print_loc_and_inst() generatings a fault.

Canonicalize all #includes.

branches: 1.2.4;
add explicit rcs id
