Extended-remote catch exec
This patch implements exec catchpoints for extended-remote Linux
targets. The implementation follows the same approach used for
fork catchpoints, implementing extended-remote target routines for
inserting and removing the catchpoints by just checking if exec events
are supported. Existing host-side code and previous support for
extended-remote exec events takes care of the rest.
gdb/ChangeLog:
* remote.c (remote_exec_event_p): New function.
(remote_insert_exec_catchpoint): New function.
(remote_remove_exec_catchpoint): New function.
(init_extended_remote_ops): Initialize extended_remote_ops
members to_insert_exec_catchpoint and
to_remove_exec_catchpoint.
