Refactor asynchronous socket APIs
The initial implementation was a bit too complex in two ways:
1. Each component (the connector, and async socket) had its own set of state and
action enums, which was confusing, required value translation, and was not really
needed. So, all these enums have been combined into two common enums that are now
declared in android/async-io-common.h
2. Too many callbacks, which really complicated implementation of the clients. It is
much more efficient to have just two callbacks (one to monitor connection, and another
to monitor I/O), letting the client to dispatch on particular event (success/timeout/etc.)
This CL fixes these two issues.
