vmdk: Move l1_size check into vmdk_add_extent()

This header check is common to VMDK3 and VMDK4, so move it into
vmdk_add_extent().

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

for vmstate accesses (which are stored beyond the end of regular image...

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....
