a98f49f46a qemu-iotests: exclude vxhs from image creation via protocol
The protocol VXHS does not support image creation.  Some tests expect
to be able to create images through the protocol.  Exclude VXHS from
these tests.

339f06a3bc qemu-iotests: tests: do not set unused tmp variable
The previous commit removed the last usage of ${tmp} inside the tests
themselves; the only remaining users are sourced by check. So we can now
drop this variable from the tests.

5262caa754 iotests: Prepare for refcount_bits option
Some tests do not work well with certain refcount widths (i.e. you
cannot create internal snapshots with refcount_bits=1), so make those
widths unsupported.

Furthermore, add another filter to _filter_img_create in common.filter
which filters out the refcount_bits value.

This is necessary for test 079, which does actually work with any
refcount width, but invoking qemu-img directly leads to the
refcount_bits value being visible in the output; use _make_test_img
instead which will filter it out.

c05e4667be qcow2: Fix L1 allocation size in qcow2_snapshot_load_tmp() (CVE-2014-0145)
For the L1 table to loaded for an internal snapshot, the code allocated
only enough memory to hold the currently active L1 table. If the
snapshot's L1 table is actually larger than the current one, this leads
to a buffer overflow.

6b7d4c5558 qcow2: Fix copy_sectors() with VM state
bs->total_sectors is not the highest possible sector number that could
be involved in a copy on write operation: VM state is after the end of
the virtual disk. This resulted in wrong values for the number of
sectors to be copied (n).

The code that checks for the end of the image isn't required any more
because the code hasn't been calling the block layer's bdrv_read() for a
long time; instead, it directly calls qcow2_readv(), which doesn't error
out on VM state sector numbers.

fef9c19139 qemu-iotests: Quote $TEST_IMG* and $TEST_DIR usage
A lot of image filename and paths are used unquoted.  Quote these to
make sure that directories / filenames with spaces are not problematic.
