dc4c5bf55a Revert to using epoll_wait().
This change depends on the kernel having been patched to use hrtimers
instead of jiffies for scheduling epoll timeouts.

54e1cdacd2 Switch Looper back to using poll() instead of epoll().
Added a couple of micro-optimizations to avoid calling wake() unnecessarily
and reduce JNI overhead slightly.

Fixed a minor issue where we were not clearing the "next" field of Messages
returned by the MessageQueue so the Message would hold on to its successor
and potentially prevent the GC from collecting it if the message were leaked
somehow.

61a25b2490 Looper: use pthread_once for TLS key initialization.
Also fix a Valgrind complaint by zeroing out the entire epoll event
struct since otherwise the data field union would be partly
uninitialized (but not in a harmful way).

b0619e8ad8 Looper: Drop default parameters in favor of a safer overload.
The idea is that if you're writing code that wants fd/events/data on
return from pollOnce() / pollAll() you should really pass in all of those
arguments.  When I changed the Looper API earlier, it was difficult
to ensure that all callers were passing the right parameters since they
were relying on default parameters to some degree so usage mistakes
would not have been caught by the compiler.

59abe7e090 Replace epoll() with poll() and rename PollLoop to Looper.
As part of this change, consolidated and cleaned up the Looper API so
that there are fewer distinctions between the NDK and non-NDK declarations
(no need for two callback types, etc.).

Removed the dependence on specific constants from sys/poll.h such as
POLLIN.  Instead looper.h defines events like LOOPER_EVENT_INPUT for
the events that it supports.  That should help make any future
under-the-hood implementation changes easier.

Fixed a couple of compiler warnings along the way.
