commit 142a8a00ed7a39864de4d2da7e9b246725c0bf2e
Author: Hsiangkai Wang <hsiang...@gmail.com>

gdb_server: add target_debug_reason for program exit detection
Currently, there is no way to notify gdb that program has exited.
Add new target_debug_reason called DBG_REASON_EXIT to notify gdb
the condition has occured. If the debug reason is DBG_REASON_EXIT,
gdb_server will send 'W' packet to tell gdb the process has exited.
