aio: add generic thread-pool facility
Add a generic thread-pool. The code is roughly based on posix-aio-compat.c,with some changes, especially the following:
- use QemuSemaphore instead of QemuCond;
- separate the state of the thread from the return code of the worker...
aio: add Win32 implementation
The Win32 implementation will only accept EventNotifiers, thus a fewdrivers are disabled under Windows. EventNotifiers are a good matchfor the GSource implementation, too, because the Win32 port of gliballows to place their HANDLEs in a GPollFD....

event_notifier: add Win32 implementation
aio: provide platform-independent API
This adds to aio.c a platform-independent API based on EventNotifiers, thatcan be used by both POSIX and Win32.

build: move cutils.o and qemu-timer-common.o to oslib-obj-y
janitor: move iovector functions out of cutils.c
This removes the dependency of cutils.c on iov.c, and lets us removeiov.o from several builds.
qmp: add NBD server commands
Adding an NBD server inside QEMU is trivial, since all the logic isin nbd.c and can be shared easily between qemu-nbd and QEMU itself.The main difference is that qemu-nbd serves a single unnamed export,while QEMU serves named exports....
block: add close notifiers
