Fix mailbox corruption in imap4d.
Delivery of a signal when a previous signal was being handled caused
mailbox corruption.
* imap4d/imap4d.c (imap4d_child_signal_setup): New function.
(imap4d_mainloop): Call imap4d_child_signal_setup.
* imap4d/signal.c (imap4d_child_signal): Reset all signal handlers
before doing actual job.
* lib/signal.c (mu_set_signals): Use sigaction.
