Replace two fat signal handlers with function calls in
the main I/O multiplex loop.  select() now watches
a pipe which is written by the new skinny signal
handlers and the received signals are handled inside
the loop sequencially.

This eliminates a complex signal mask to guarantee
async-signal safety.
