The purpose of the test runner is to prepare the test environment (e.g. create
a work directory, a test image, etc), execute a program under test with
parameters, indicate a test failure if the program was killed during the test
execution and collect core dumps, logs and other test artifacts.
The test runner doesn't depend on an image format, so it can be used with any
external image generator.
[Fixed path to qcow2 format module "qcow2" instead of "../qcow2" since
runner.py is no longer in a sub-directory.

Commit 58ac321135 introduced a check to ide dma processing which
constrains all requests to drive size. However, apparently, some
valid requests (like TRIM) does not fit in this constraint, and
fails in 2.1. So check the range only for reads and writes.

Parallels has released in the recent updates of Parallels Server 5/6
new addition to his image format. Images with signature WithouFreSpacExt
have offsets in the catalog coded not as offsets in sectors (multiple
of 512 bytes) but offsets coded in blocks (i.e. header->tracks * 512)
In this case all 64 bits of header->nb_sectors are used for image size.
This patch implements support of this for qemu-img and also adds specific
check for an incorrect image. Images with block size greater than
INT_MAX/513 are not supported. The biggest available Parallels image
cluster size in the field is 1 Mb. Thus this limit will not hurt
anyone.

Parallels image format has several additional fields inside:
- nb_sectors is actually 64 bit wide. Upper 32bits are not used for
images with signature "WithoutFreeSpace" and must be explicitly
zeroed according to Parallels. They will be used for images with
signature "WithouFreSpacExt"
- inuse is magic which means that the image is currently opened for
read/write or was not closed correctly, the magic is 0x746f6e59
- data_off is the location of the first data block. It can be zero
and in this case data starts just beyond the header aligned to
512 bytes. Though this field does not matter for read-only driver
This patch adds these values to struct parallels_header and adds
proper handling of nb_sectors for currently supported WithoutFreeSpace
images.
WithouFreSpacExt will be covered in next patches.
