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

odyssey: major router and shared logic rework Goal is to improve overall performance during massive peaks of connecting clients. This patch makes router a shared structure, instead of being run in separate system worker thread/coroutine. Now router and each route object is protected by separate mutex. Worker threads directly access router object without calls to separate thread.
