scd: Fix for GNU/Linux suspend/resume.
* configure.ac (require_pipe_to_unblock_pselect): Default is "yes".
* scd/scdaemon.c (scd_kick_the_loop): Minor clean up.
--
Normally SIGCONT or SIGUSR2 works for unblocking pselect. But on my
machine with GNU/Linux, when a machine is suspend/resume-ed, pselect
keeps blocked, while signal itself is delivered.
It's better to use pipe.
