Require the machine-dependant DDB commands to be in db_machine_command_table[]
...
and link it directly to db_command_table[] so that it's not necessary
to do this at runtime. Make db_machine_command_table[] const on all ports.
g/c now unneded stuff, like db_machine_commands_install(), db_machine_init()

New syscall entry implementation based on the Alpha version
...
as hacked by mycroft.
- Use syscall_intern() to give a process a plain or fancy
syscall based on ktrace flags.
- Avoid copying from the trapframe into a local array as much
as possible.
Yields roughly 5% improvement on a 25MHz R3000 (DECstation 5000/200)
on a simple syscall benchmark.
There's still some work that can be done using __HAVE_MINIMAL_EMUL.

Put signal posting back in userret() for now; for it to work

AST to be posted when delivering signals, or after a process

- Move all signal posting to ast(). userret() is now a one-liner.
