Even though it's just the reserved space, make sure they're zeroes.

Add a routine that can be used to engage the AHCI
device at a not-granular level so that bringing up
the functionality of the HBA is easy in future tests
that are not concerned with testing the bring-up process.

These test a few different pathways in the AHCI code.
short: Test the minimum transfer size, exactly one sector.
simple: Test a transfer using a single PRD, in this case, 4K.
double: Test transferring 8K, which we will split up as two PRDs.
long: Test transferring a lot of data using many PRDs, 256K.

In addition to DMA tests, test PIO and LBA48 command pathways in AHCI.
To accomplish this, a primitive multiplexer for gtest is added.
Though guests may prefer not to issue PIO commands directly except
for single sector cases during early boot and shutdown, these pathways
are still used for the transfer of ATAPI commands as well, and should
be behaving well.

This will enable the testing of high offsets without
wasting a lot of disk space, and does not impact the
previous tests.
mkimg and mkqcow2 are added to libqos for other tests.

This function only exists since glib 2.34. Dropping the following
patches from the queue:
pick 23134a5 qtest/ahci: add qcow2 support to ahci-test
pick 6ca5609 qtest/ahci: test different disk sectors
pick e2f0dee qtest/ahci: Add simple flush test
pick 396491b qtest/ahci: Allow override of default CLI options
pick eb8c8bd libqtest: add qmp_eventwait
pick 398bfc3 libqtest: add qmp_async
pick d3f77d1 libqos: add blkdebug_prepare_script
pick d628e51 qtest/ahci: add flush retry test
This is patch 7 and 8 from this series and the complete series "ahci:
rerror/werror=stop resume tests", which seems to depend on them.

Do we have a policy on glib version for qtests? I know we require a
specific version for within QEMU itself, but there are many instances of
functions newer than that being using in qtests already.

I would have assumed that it's the same requirement and make check
should work whereever you can build qemu. In practice, however, I'm
running qtests on a RHEL 6 host (without this series that still works
fine) and complaining only if things break there.

It looks like we currently require 2.12 for the basic builds, but pretty
much the entirety of the gtest framework itself was introduced in 2.16,
hence the ask.
I saw some discussion recently of bumping the glib version required, but
I think MST circumvented the need to do so for the time-being.
Still, we should at least bump this up to 2.16 to have some consistency
with the testing framework... Or acknowledge that the testing framework
may have a different set of requirements.

I'm looking at this some more. The glib code basically does this:
If windows: Set an error if rc is nonzero.
If linux: use the WIFEXITED, WIFSIGNALED or WIFSTOPPED macros to
determine the domain of the error code. If WIFEXITED, check for nonzero
status. if WIFSIGNALED, WIFSTOPPED or !WIFEXITED, return an error.
I *think* I can just generalize this all, if I am not interested in
*why* we failed, to just checking rc to be nonzero. That should be
adequately multiplatform.
Agree?
