[PULL 00/10] Block layer fixes for 8.0-rc4

[Kevin Wolf]

At the first sight, this one probably looks huge for -rc4. But it's
mainly because Paolo split his fix into many very small patches. As you
can see in the diffstat below, it's not all that bad (and half of the
insertions there are for a new test case for the VHDX corruption bug).

The following changes since commit dda860b9c031d6a2768f75e5e622545d41d4b688:
