WIP: switch to libevent for node socket handling #11227
Not yet ready for review. This can be considered a staging area. Chunks of this will be PR'd until only the actual libevent switch-over is ready, at which point this PR should be ready for review.
These changes remove our old select() loop for socket handling in favor of libevent, which uses epoll/kqueue/etc. as a back-end. In addition to being faster and more efficient, this allows us to drop some annoying restrictions, namely that select can only handle 1024 sockets in practice on most systems.
Note that this does not yet make the switch to libevent for outgoing connections, that work is happening in parallel, and will be easier to merge after this.
Also, for any reviewers, several of these commits would individually introduce some regressions or slow-downs, but they've been split up in order to clarify why some of the changes are being made.
