Yes, this is a good idea.  Sorry for the delay; I checked in this
patch, to change the output to hexadecimal.  Tested on x86_64-linux.

I've just realized that the test change won't work on remote
debugging; I'll fix up linux-dp.exp.

	* linux-thread-db.c (thread_db_pid_to_str): Print thread IDs
	as hexadecimal.

	* gdb.threads/linux-dp.exp: Expect hexadecimal thread IDs.
	* gdb.threads/print-threads.exp (test_all_threads): Allow
	negative and hexadecimal thread IDs.
