  Add priorities for the fds in reactor.

It is important to have priorities between the fds triggered in reactor/poll. Operations like timer or async resume must have priority over reading new SIP messages from network.
Current code generically implements a priority mechanism, for all types of polling. We may optimize it in the next weeks, with specific implementations for each type of polling.
