win32-aio: drop win32_aio_flush_cb()

The io_flush argument to qemu_aio_set_event_notifier() has been removed
since the block layer learnt to drain requests by itself. Fix the
Windows build for win32-aio.o by updating the
qemu_aio_set_event_notifier() call and dropping win32_aio_flush_cb()....

vmdk: fix L1 and L2 table size in vmdk3 open

VMDK3 header has the field l1dir_size, but vmdk_open_vmdk3 hardcoded the
value. This patch honors the header field.

And the L2 table size is 4096 according to VMDK spec1, instead of
1 << 9 (512).

vmdk: support vmfsSparse files

VMware ESX hosts use a variant of the VMDK3 format, identified by the
vmfsSparse create type ad the VMFSSPARSE extent type.

It has 16 KB grain tables (L2) and a variable-size grain directory (L1).
In addition, the grain size is always 512, but that is not a problem...

vmdk: support vmfs files

VMware ESX hosts also use different create and extent types for flat
files, respectively "vmfs" and "VMFS". This is not documented, but it
can be found at http://kb.vmware.com/kb/10002511 (Recreating a missing
virtual machine disk (VMDK) descriptor file)....

block: Introduce bs->zero_beyond_eof

In 4146b46c42e0989cb5842e04d88ab6ccb1713a48 (block: Produce zeros when
protocols reading beyond end of file), we break qemu-iotests ./check

qcow2: Change default for new images to compat=1.1

By the time that qemu 1.7 will be released, enough time will have passed
since qemu 1.1, which is the first version to understand version 3
images, that changing the default shouldn't hurt many people any more...

aio: drop io_flush argument

The .io_flush() handler no longer exists and has no users. Drop the
io_flush argument to aio_set_fd_handler() and related functions.

The AioFlushEventNotifierHandler and AioFlushHandler typedefs are no
longer used and are dropped too....
