Currently the file size requested by user is rounded down to nearest
sector, causing the actual file size could be a bit less than the size
user requested. Since some formats (like qcow2) record virtual disk
size in bytes, this can make the last few bytes cannot be accessed.
This patch fixes it by rounding up file size to nearest sector so that
the actual file size is no less than the requested file size.

Huge values for header.cluster_bits cause unbounded allocations (e.g.
for s->cluster_cache) and crash qemu this way. Less huge values may
survive those allocations, but can cause integer overflows later on.
The only cluster sizes that qemu can create are 4k (for standalone
images) and 512 (for images with backing files), so we can limit it
to 64k.

The first test case would cause a huge memory allocation, leading to a
qemu abort; the second one to a too small malloc() for the catalog
(smaller than s->catalog_size), which causes a read-only out-of-bounds
array access and on big endian hosts an endianess conversion for an
undefined memory area.
The sample image used here is not an original Parallels image. It was
created using an hexeditor on the basis of the struct that qemu uses.
Good enough for trying to crash the driver, but not for ensuring
compatibility.

This test checks for proper bounds checking of some VDI input
headers. The following is checked:
1. Max image size (1024TB) with the appropriate Blocks In Image
value (0x3fffffff) is detected as valid.
2. Image size exceeding max (1024TB) is seen as invalid
3. Valid image size but with Blocks In Image value that is too
small fails
4. Blocks In Image size exceeding max (0x3fffffff) is seen as invalid
5. 64MB image, with 64 Blocks In Image, and 1MB Block Size is seen
as valid
6. Block Size < 1MB not supported
7. Block Size > 1MB not supported
[Max Reitz <mreitz@redhat.com> pointed out that "1MB + 1" in the test
case is wrong. Change to "1MB + 64KB" to match the 0x110000 value.

This new test case uses nbd-fault-injector.py to simulate broken TCP
connections at each stage in the NBD protocol. This way we can exercise
block/nbd-client.c's socket error handling code paths.
In particular, this serves as a regression test to make sure
nbd-client.c doesn't cause an infinite loop by leaving its
nbd_receive_reply() fd handler registered after the connection has been
closed. This bug was fixed in an earlier patch.

This adds the VHDX format to the qemu-iotests format, and adds
a read test. The test reads from an existing sample image, that
was created with Hyper-V under Windwos Server 2012.
The image file is a 1GB dynamic image, with 32MB blocks.
The pattern 0xa5 exists from 0MB-33MB (past a block size boundary)
The pattern 0x96 exists from 33MB-66MB (past another block boundary,
and leaving a partial blank block)
From 66MB-1024MB, all reads should return 0.
Although 1GB dynamic image with 66MB of data, the bzip2'ed image
file size is only 874 bytes.
This also adds in the IMGFMT_GENERIC flag, so r/o images can be
