vmdk: Make VMDK3Header and VmdkGrainMarker QEMU_PACKED

It's best to make it consistent that all on disk structures are
QEMU_PACKED.

vmdk: use unsigned values for on disk header fields

The size and offset fields are all non-negative values, use uint64_t for
them to avoid getting negative in memory value by int overflow.

vmdk: check granularity field in opening

Granularity is used to calculate the cluster size and allocate r/w
buffer. Check the value from image before using it, so we don't abort()
for unbounded memory allocation.

vmdk: check l2 table size when opening

header.num_gtes_per_gte determines size for L2 table. Check for too big
value before using it. Limit to 512M entries (2GB per one L2 table).

vmdk: check l1 size before opening image

L1 table size is calculated from capacity, granularity and l2 table
size. If capacity is too big or later two are too small, the L1 table
will be too big to allocate in memory. Limit it to a reasonable range.

vmdk: use heap allocation for whole_grain

We should never grow the stack beyond 1 MB, otherwise we'll fall off the
end. Thread stacks and coroutine stacks (1 MB) do not grow.
get_cluster_offset() allocates a big stack offset, it will fail for big
cluster images, change to heap allocated buffer....

vmdk: rename num_gtes_per_gte to num_gtes_per_gt

num_gtes_per_gte is a historical typo, rename it to a more sensible
name. It means "number of GrainTableEntries per GrainTable".

sheepdog: add missing .bdrv_has_zero_init

Commit 3ac21627 changed the behaviour of bdrv_has_zero_init() to default
to 0. In the review for Sheepdog it turned out that enabling it is safe,
so that commit updated one BlockDriver definition of sheepdog to use...
