wrong thread, make sure to write the fixed PC value into the thread
        that stopped.  Restart all threads after single stepping over a
        breakpoint for a different thread.
        * breakpoint.c (set_momentary_breakpoint): Make momentary
        breakpoints thread specific in a multi-threaded program.
        * lynx-nat.c (child_resume): Add some comments.  Correctly
        choose between the single and multi-threaded step and continue
        ptrace calls.

Some of the lynx-6100 single stepping fixes.
