Previously dead peer detection timer was scheduled every dpd_interval,
added dpd_interval to all of the clients timestamp and if timestamp was
larger than client hearbeat interval * 1.2 then check if client sent
some message. If so, flag was reset.
This method was source of number of problems so instead different method
is now used.
Every single client has its own timer with timeout based on
(configurable) dpd_interval_coefficient and multiplied with
client heartbeat timeout. When message is received from client timer is
rescheduled. When timer callback is called (= client doesn't sent
message during timeout) then client is disconnected.

IPC and TLS sockets are read only, so write callbacks should never
happen (specifically tested in pr-poll-loop test) so remove them.

Previously, when user tried start corosync-qnetd without
initialized NSS database then generic (not very helpful
and misleading) NSS error was logged
"NSS error (-8015): The certificate/key database is in an old,
unsupported format.".
Solution is to check if it's possible to open NSS DB directory and
display (usually much more informative) result of strerror function.
Such check is called before fork, so init system can return error code
during start.
