This extends the previous work in #3733 with the following: 1. Remove buffer coalescing, as this could result in a race condition during the `writev` syscall in rare circumstances 2. Add a third buffer size, to ensure that we aren't allocating more than we need to without coalescing 3. Refactor buffer handling in the WebSocket code to reduce allocations and ensure owned buffers aren't incorrectly being pooled resulting in further race conditions Fixes nats-io/nats.ws#194.
