d5ed42ea19 When doing a reboot from ddb, set panicstr, so that later LOCKDEBUG checks

85dcbb2bb9 db_cmd_search: When we compare names we'd better stop at the nul byte.

cd2cd2dd63 Do another setjmp right before entering the command loop, we do not want 
to execute the on-enter commands again on errors.

9b58206ecf Some cleanup: 
- When registering command tables, make sure the builtin commands are
   already registered
 - Make the command table entry structure private
 - Do not bother to store the number of commands in a table, we can quickly
   calc that if needed.

cadfc6aaa0 No need to db_init_commands() early any more - it will happen on first

463076317b Special case the initialization of builtin command tables to avoid using 
malloc. Fixes PR kern/37042.
Allow "mach" commands registered by LKMs even if there is no builtin
mach command for the arch.

34bb6e19fd Minor clenaup - db_cmd_loop_done is a bool nowadays, so use true/false 
instead of 0/1.
Also make db_init_commands() non-static.

99423a9d7c Simplify the "tables are already setup" test. 
Print a message on unknown commands (as we used to do before) and get rid
of the now unused macro previously used for that.

67d703cf25 Import of POSIX Asynchronous I/O. 
Seems to be quite stable. Some work still left to do.

Please note, that syscalls are not yet MP-safe, because
of the file and vnode subsystems.

b5329c1d85 (1) Don't print the message buffer (via ddb's dmesg command) if the 
message buffer has not yet been set up, mimicking code from the top of
the sysctl routine for retrieving the message buffer.

(2) Add a /l modifier to the trace command.  This makes it print the
backtrace using printf() instead of db_printf(), which has the nice
side-effect of also putting it into the message buffer.  A kernel with
ddb in it but disabled (ie, ddb.onpanic set to zero) will print a
backtrace (which ends up in the message buffer) before dumping (or
not, depending on the value of kern.dump_on_panic) and rebooting, but
if ddb is not disabled, the backtrace is not printed, and there's no
way to get it to display a backtrace such that you can retrieve it
after the dump.  The backtrace printed by gdb is sometimes a little
different.

(3) Documentation for the above.
