Signal handler cleanup.
* mainloop.c (fatal_handler): New. Cleanly handle
unexpected fatal signals.
(setup_main_signals): New. Set signals once mainloop
is entered.
(setup_signals): New. Block certain signals during initialization.
Set handler for fatal signals.
* relay.c (reader_thread): Use ppoll(). Terminate on
SIGUSR2 after reading any remaining data.
(close_relayfs): Remove sleep hack. Send SIGUSR2 to all threads.
Runtime debug messages.
* staprun.h: Change dbug() to accept a debuglevel and
enable it.
* *.c: Modify dbug() calls.
