odyssey: major io rework and refactoring This patch moves Odyssey from stream based write caching to message driven. All write operations are delayed and happen on a group of messages. This removes necessity to do IO and wait for write completion during calls from SSL_write() context. Write timings should behave more predictable now and number of used syscalls should be also decreased. This patch also simplifies caching management. All clients are simply reusing cached messages without prolonged contention. Several configuration options are no longer used: pipeline, cache, cache_chunk 2018-08-28 14:43:46 +00:00			`#ifndef ODYSSEY_INSTANCE_H`
