Hopefully this will reduce the flakiness of PostDelayedTask.

The new constructor introduces two new changes:
* Support specifying thread priority at construction time.
- Moving forward, the SetPriority() method will be removed.
* New thread function type.
- The new type has 'void' as a return type and a polling loop
inside PlatformThread, is not used.
The old function type is still supported until all places have been moved over.
In this CL, the first steps towards deprecating the old mechanism are taken
by moving parts of the code that were simple to move, over to the new callback
type.

Multimedia timers are higher precision than WM_TIMER, but they're also
a limited resource and more costly. So this implementation is a best
effort implementation that falls back on WM_TIMER when multimedia
timers aren't available.
A possible future change could be to make high precision timers in a
TaskQueue, optional. The reason for doing so would be for TaskQueues
that don't need high precision timers, won't eat up timers from TQ
instances that really need it.

There's no longer any need to make the two arguments have the same
signedness, so we can remove a bunch of superfluous (and sometimes
dangerous) casts.
It turned out I also had to fix the safe_cmp functions to properly handle
enums that are implicitly convertible to integers.

The issue was that if the main entry routine of the thread would get called before the first APC, the thread would hang on a GetMessage() call and the APC sent to initialize the thread, would never run.

Reason for revert:
Reverting after experiment. What seems to happen is that the thread can't be stopped when PostThreadMessage fails with this error code (or lack thereof).

New task queueing primitive for async tasks: TaskQueue.
TaskQueue is a new way to asynchronously execute tasks sequentially
in a thread safe manner with minimal locking. The implementation
uses OS supported APIs to do this that are compatible with async IO
notifications from things like sockets and files.
This class is a part of rtc_base_approved, so can be used by both
the webrtc and libjingle parts of the WebRTC library. Moving forward,
we can replace rtc::Thread and webrtc::ProcessThread with this implementation.
NOTE: It should not be assumed that all tasks that execute on a TaskQueue,
run on the same thread. E.g. on Mac and iOS, we use GCD dispatch queues
which means that tasks might execute on different threads depending on
what's the most efficient thing to do.

Reason for revert:
sigh. Have to revert again as there seems to have have been some change made for pnacl and CrOS.
