This series simplifies heavily aio_poll by splitting it into three
phases: prepare (aio_compute_timeout), poll, dispatch. The resulting
code shares more logic between aio_poll and the GSource wrappers,
and makes it easier to add Win32 support for sockets.
Win32 support for sockets is a prerequisite for moving the NBD server
into the BlockDriverState's attached AioContext. It is done in the
final patch, based on earlier work from Or Goshen (from Intel).
I had to more or less rewrite it to fit the new framework, but you
can see parts of Or's work, as well as traces of aio-posix.c and
main-loop.c logic.
Tested with NBD boot under Wine.

Paolo Bonzini (10):
AioContext: take bottom halves into account when computing aio_poll
timeout
aio-win32: Evaluate timers after handles
aio-win32: Factor out duplicate code into aio_dispatch_handlers
AioContext: run bottom halves after polling
AioContext: export and use aio_dispatch
test-aio: test timers on Windows too
aio-win32: add aio_set_dispatching optimization
AioContext: introduce aio_prepare
qemu-coroutine-io: fix for Win32
aio-win32: add support for sockets
