dispatch: move into its own source file This was part of osdep/threads.c out of laziness. But it doesn't contain anything OS dependent. Note that the rest of threads.c actually isn't all that OS dependent either (just some minor ifdeffery to work around the lack of clock_gettime() on OSX).

player: use better way to wait for input and dispatching commands Instead of using input_ctx for waiting, use the dispatch queue directly. One big change is that the dispatch queue will just process commands that come in (e.g. from client API) without returning. This should reduce unnecessary playloop excutions (which is good since the playloop got a bit fat from rechecking a lot of conditions every iteration). Since this doesn't force a new playloop iteration on every access, this has to be enforced manually in some cases. Normal input (via terminal or VO window) still wakes up the playloop every time, though that's not too important. It makes testing this harder, though. If there are missing wakeup calls, it will be noticed only when using the client API in some form. At this point we could probably use a normal lock instead of the dispatch queue stuff.
