After discussing with Andrew, it was suggested that watchthreads.exp be given 
its own C file which is a copy of schedlock.c.  This new patch replaces the old 
one below.  Hopefully, someone will get a chance to look at it.

Ok to commit?

          * gdb.threads/watchthreads.c: New file for use by watchthreads.exp. 

          * gdb.threads/watchthreads.exp: Use gdb_get_line_number to find
          breakpoint lines and switch to use watchthreads.c.
