I should remember to add options in README.

PATH_MAX is not in c99 and also struct ip_mreq. With -std=c99
tsdecrypt do not compile with gcc 4.5.

This workaround is no longer needed because camd socket is now set
TCP_NODELAY and this fixes OSCAM communication.

This way it works better when many packets are sended. Without
NODELAY, OSCAM sometimes gets packets boundaries wrong especially
when there are lots of packets (test with emm stream of 16000+
packets per minute).

Without this the STOP event was lost most of the times because
tsdecrypt exited before the thread delivered the event.

This prevents unnececary warnings. Sometimes OSCAM responds with error
and on the next query everything is OK. So before raising errors flags
try a couple of times.

This fix prevents segfault on exit.

Use different queues for ECMs and EMMs. This allows to process
ECMs before EMMs, preventing the case where too much incoming
EMMs slow down ECM processing and interfere with getting the code
words on time.
