qemu-iotests: Add regression test for b7ab0fea

It turned out that the change in b7ab0fea was actually a real qcow2
corruption fix. This is a reproducer for the bug.

block: Fix is_allocated_above with resized files

In an image chain, if the base image is smaller than the current
image, we need to make sure to use the current images count of
unallocated blocks once we get to the end of the base image. Without
this change the code will return 0 blocks when it gets to the end
of the base image and mirror_run will fail its assertion.

block: Adds mirroring tests for resized images

This test verifies two mirroring issues are fixed with resized images:

 * sync='top' creates an image that is the proper size
 * sync='full' doesn't cause an assertion failure and crash qemu

vmdk: Allow selecting SCSI adapter in image creation

Introduce a new option "adapter_type" when converting to vmdk images.
It can be one of the following: ide (default), buslogic, lsilogic
or legacyESX (according to the vmdk spec from vmware).

In case of a non-ide adapter, heads is set to 255 instead of the 16.
The latter is used for "ide".

dmg: Fix bdrv_open() error handling

Return -errno instead of -1 on errors and add error checks in some
places that didn't have one. Passing things by reference requires more
correct typing, replaced a few off_ts therefore - with a 32-bit off_t
this is even a fix for truncation bugs.

While touching the code, fix even some more memory leaks than in the
other drivers...

vmdk: Allow space in file name

The previous scanf() format string stopped parsing the file name on the
first white white space, which seems to be allowed at least by VMware
Workstation.

Change the format string to collect everything between the first and
second quote as the file name, disallowing line breaks.
