Further threading and API restructuring for logging and input

frameworks.

There were a number of cases that weren't thread-safe. In particular,
we don't use std::string anymore for anything that's passed between
threads (but instead plain old const char*, with manual memmory
managmenet).

This is still a check-point commit, I'll do more testing.
