scd: Wake up the select when new USB scan.
* scd/scdaemon.c (update_fdset_for_usb): Wake up the select(2).
(handle_connections): Use a kind of "self-pipe" technique.
--
Use pipe to wake up select(2). If UNIX-only, signal could be used. For
portability, "self-pipe" is better, here. Setup for non-blocking for
pipe fds are not needed, because speed of USB device insertion is
limited by human physical interaction; No one can do hundreds of
device insertion/removal-s per second.
