This factors out the boiler-plate code from the sample app to a common glue code that can be used for everyone writing this style of app: a dedicated app thread that takes care of waiting for events and processing them. As part of doing this, ALooper has a new facility to allow registration of fds that cause ALooper_pollOnce() to return the fd that has data, allowing the app to drive the loop without callbacks. Hopefully this makes some people feel better. :) Also do some other cleanup of the ALooper API, plus some actual documentation. Change-Id: Ic53bd56bdf627e3ba28a3c093faa06a92be522b8
