Add a test for vmdk files which use a file with a JSON file name, and
which then try to open extents. That should fail and the error message
should at least try to look helpful.

There are two instances of iotest 059 using qemu-io on a qcow2 image. As
of "qemu-iotests: Use qemu-io -f $IMGFMT" the iotests can no longer rely
on $QEMU_IO doing probing, therefore the qcow2 format has to be
specified explicitly here.

It's possible that we diverge from the specification with our
implementation. Having a reference image in the test cases may detect
such problems when we introduce a bug that can read what it creates, but
can't handle a real VMDK.

all these tests do anything of the following and thus fail with any
protocol other than file:
- the tests use rm, cp or mv shell commands which only work on file
- the tests use qcow2.py
- the images construct new filenames (e.g. backing file names) and
the logic is broken for anything else than file

Local variable "n" as int64_t avoids overflow with large sector number
calculation. See test case change for failure case.

Some cases are not applicable for vmdk subformats those don't support
certain features, e.g. backing file, and some others can't run on
mult-file image, e.g. monolithicFlat. This adds declaration in test
cases to skip them automatically, so that iotests on vmdk can go
more smoothly (without manually picking of cases for each subformat).

VMFS extent line in description file should be with 4 fields:
RW <size> VMFS "file-name.vmdk"
Check the number explicitly and report error if offset is appended as
FLAT, which should be invalid format.

The buffer for description file was 4096 which only covers a few
hundred of extents. This changes the buffer to dynamic allocated with
g_strdup_printf in order to support bigger cases.

Move the blank line to above the test step banner, so it looks clearer

A lot of image filename and paths are used unquoted. Quote these to
make sure that directories / filenames with spaces are not problematic.

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.

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.
