Refactor a bunch of scheduler code to give basically the same behaviour
but with slightly cleaned up interfaces.

db_stack_trace() actually has a chance to parse its own arguments.
Unify db_stack_trace_cmd(). All it did was look up the thread given2004-07-21T05:07:09ZMarcel Moolenaarmarcel@FreeBSD.org2004-07-21T05:07:09Zurn:sha1:fd32d93b97086acaf80526bbb55f735b35d074fb
the thread ID and call db_trace_thread().
Since arm has all the logic in db_stack_trace_cmd(), rename the
new DB_COMMAND function to db_stack_trace to avoid conflicts on
arm.
While here, have db_stack_trace parse its own arguments so that
we can use a more natural radix for IDs. If the ID is not a thread
ID, or more precisely when no thread exists with the ID, try if
there's a process with that ID and return the first thread in it.
This makes it easier to print stack traces from the ps output.

Re-add the gdb command. It was removed to be replaced by something2004-07-12T01:38:07ZMarcel Moolenaarmarcel@FreeBSD.org2004-07-12T01:38:07Zurn:sha1:f3be7cb3e9c0d3621cd6b2e775aa1cbf77ec5eb6
more generic, but that didn't actually happen. Since the feature to
switch backends (and historically this means from DDB to GDB) is
important, make sure people can do just that until such the generic
mechanism actually sees the light of day.

Most of the changes are a direct result of adding thread awareness.
Typically, DDB_REGS is gone. All registers are taken from the
trapframe and backtraces use the PCB based contexts. DDB_REGS was
defined to be a trapframe on all platforms anyway.
Thread awareness introduces the following new commands:
thread X switch to thread X (where X is the TID),
show threads list all threads.
The backtrace code has been made more flexible so that one can
create backtraces for any thread by giving the thread ID as an
argument to trace.
With this change, ia64 has support for breakpoints.
