06dd613f03 extend 'show event' to take /i /t and /m modifiers, to select interrupt, 
trap or misc event types.  you can mix them with /f as well, to show all
including zero events for traps and misc, "show event/ftm"

912b4160fd Make 'show event', 'dmesg' work with crash(8). 
XXX dmesg fails exactly the same way as /sbin/dmesg.

cd6b1c8f08 Make ddb compile and work in userspace. Mostly this is comprised of three 
types of changes:

- Add a few new methods to replace stuff like p_find(), CPU_INFO_FOREACH.

- Use db_read_bytes() instead of accessing kernel structures directly,
  and similar changes.

- Add ifdef _KERNEL where the above hasn't been done, and an XXX comment.

4cb83f9c6e Make DDB shows right register values on 32-bit sparc64 kernels. 
- define db_expr_t as int64_t.
- %gsr is 32-bit, so use db_sparc_intop.
- sync arguments with function prototype.

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.

malloc. Fixes PR kern/37042.

mach command for the arch.

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.
