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. requested by: rwatson@ tested on: amd64, i386, ia64
