c4ccb0d0ce qemu: re-add padding to the saved state images
In the past we added 1024 bytes of padding to saved state images so that
users can run "virsh managedsave-edit $GUEST" and make XML changes which
increase the size of the XML document. This padding was accidentally
lost a while back

  commit 6b9b21db70
  Author: Peter Krempa <pkrempa@redhat.com>

    qemu: Remove unnecessary calculations in qemuDomainSaveMemory

The original 1024 bytes was unreasonably stingy when we consider that
the QEMU state is typically going to be many 100's of MB in size. Thus
this adds 64 KB of padding after the XML which should cope with any
plausible modifications a user will want to make.

199dd6f693 qemu: Add capability for IBS pSeries feature
IBS (Indirect Branch Speculation) is the last capability added
in QEMU 2.12 related to Spectre mitigation for Power. It was
added in commit 4be8d4e7d935.

This patch introduces it as QEMU_CAPS_MACHINE_PSERIES_CAP_IBS.
Like CFPC and SBBC, users might want to tune in IBS based on
their HW and guest OS requirements, and it's better to do it
so in a proper Libvirt feature than to put QEMU arguments
in the middle of the domain XML.

a cleaner way for users to tune the SBBC accordingly, given
that not all hypervisor and guest setups supports this

a0a2c8ab73 qemu: Add capability for CFPC pSeries feature
CFPC (Cache Flush on Privilege Change) is one of the capabilities
added to QEMU to mitigate Spectre vulnerabilities in Power chips.
It was implemented in QEMU 2.12 by commit 6898aed77f46.

This capability is still used today due to differences in how
the host setup (hardware and firmware/kernel) can handle this
mitigation. Its default value also varies with the pseries machine
version of the time. There's also certain OSes, like AIX, that
might not support the default value of the pseries machine the
guest uses.

Exposing this in the Libvirt XML as a feature will allow users to tune
CFPC values in a cleaner way, instead of hacking parameters in
<qemu:commandline> elements.

84a20fe8e3 qemumonitortestutils: Make test monitor failures more prominent
Until now we've tried to report errors from the test monitor code by
passing them back as failures from the qemu we simulate. This doesn't
work well in cases when the monitor logic does not detect failures or
has fallback code. Additionally there isn't much use for continuing the
test execution after first failure as in most cases the test data will
be misaligned and all other calls will fail as well.

To make the errors more obvious this patch moves away from reporting
them via the simulated monitor to reporting them to stderr and
exit()ing afterwards. While this might be less convenient
when developing tests it actually makes failures in the test suite
really obvious and doesn't require any opt-in from the tests themselves.

f8d6b319a6 virStorageSourceParseNBDColonString: Rewrite to match what qemu does
Our implementation wasn't quite able to parse everything that qemu does.
This patch rewrites the parser to a code that semantically resembles the
combination of 'nbd_parse_filename' and 'inet_parse' methods in qemu to
be able to parse the strings in an equivalent manner.

The only thing that libvirt doesn't do is to check the lengths of
various components in the nbd string in places where qemu uses constant
size buffers.

The test cases validate that some of the corner cases involving colons
are parsed properly.

b8c02497b3 mock: qemuDomainGetUnplugTimeout: Decrease timeout
We always queue the DEVICE_DELETED events before successful return from
the command so that tests are reliable. This means we can decrease the
unplug timeout as it's guaranteed to be executed in correct order.

According to my testing it shaves off ~450ms of test run:

real	0m0.721s

vs.

real	0m0.259s

2ab8dba58c qemuDomainGetUnplugTimeout: Add G_GNUC_NO_INLINE
The function is mocked in qemuhotplugmock.so. Recent clang versions
decided to inline it so the mock stopped working resulting in
qemuhotplugtest wasting 15 seconds waiting for timeouts.
