Set names of worker threads
This adds some configury so that gdb can set the names of worker
threads. This makes them show up more nicely when debugging gdb
itself.
2019-11-26 Tom Tromey <tom@tromey.com>
* gdbsupport/thread-pool.c (thread_pool::set_thread_count): Set
name of worker thread.
* gdbsupport/common.m4 (GDB_AC_COMMON): Check for
pthread_setname_np.
* configure, config.in: Rebuild.
