odyssey: major rework of io architecture This patch intend is to improve overall io performance, reduce cpu and system usage. Machinarium: IO read/write logic is highly simplified and now based on conditions instead of previously made internal readahead buffer and msg queues. This allows to give user more control over io operations and avoid doing undesired readahead copying. Above that, TLS implementation reworked to use async logic instead of separate BIO layer. Direct pooling functions removed. New objects machine_cond_t and machine_iov_t objects. Odyssey: Introduced readahead, io and relay objects. Relay allows to connect two io handles for direct data retransmission without double copying. Removed configuration options no longer needed: packet_read_size, packet_write_queue
