Since the exec family of functions does not reset the signal
disposition of signals set to SIG_IGN, in order to be transparent,
when spawning new child processes to debug (with "run", etc.), we
must reset all signal dispositions back to what was originally
inherited from gdb/gdbserver's parent, just before execing the
target program to debug. */
