Pass SIGLIBRT directly to child processes.
FreeBSD's librt uses SIGLIBRT as an internal signal to implement
SIGEV_THREAD sigevent notifications. Similar to SIGLWP or SIGCANCEL
this signal should be passed through to child processes by default.
include/ChangeLog:
* signals.def: Add GDB_SIGNAL_LIBRT.
gdb/ChangeLog:
* common/signals.c (gdb_signal_from_host): Handle SIGLIBRT.
(do_gdb_signal_to_host): Likewise.
* infrun.c (_initialize_infrun): Pass GDB_SIGNAL_LIBRT through to
programs.
* proc-events.c (signal_table): Add entry for SIGLIBRT.
