trap: Implement POSIX.1-2008 trap reset behaviour
Jonathan Perkin submitted a patch to fix the behaviour of trap
when the first argument is an integer.  Currently it is treated
as a command while POSIX requires it to be treated as a signal.

This patch is based on his idea but instead of adding an extra
argument to decode_signal I have added a new decode_signum helper.
