This is code parsing RSP signal numbers, checking whether the numbers
are indeed valid/known GDB signals, and then converting to host signal
numbers. I considered adding temporary enum gdb_signal variables
instead, but didn't really like the result.

* server.c (handle_v_cont, process_serial_event): Add enum
gdb_signal casts to signal parsing code.
