MFC rev 1.39:
- One can now specify the decimal pid of a process to trace as a parameter.
  Since pid's are not in the kernel address space, this doesn't conflict
  with the funcionality of specifying an arbitrary frame pointer to the
  trace command.
- If the first function of a backtrace maps to fork_trampoline, then this
  is a newly fork'd process that has not been executed yet, so just print
  out the first frame and then return for that case.
- Lower the default count from 65535 to 1024.  ddb doesn't trace into
  userland, and if the stack gets hosed and starts looping it's less
  annoying.

Partial MFC of rev 1.40:
- Don't try to trace a swapped-out process.  (Brought over from NetBSD via
  the new alpha trace code.)
