42558a43f8 qemu: capabilities: Re-enable detection of QEMU_CAPS_BLOCK_EXPORT_ADD
Now that qemu stabilized it's interface and we've switched to the new
design we can re-enable use of 'block-export-add'

1c2314b938 qemu: Update to new design of 'block-export-add'
qemu decided to modify the arguments of 'block-export-add' to include an
array of bitmaps rather than a single bitmap.

Since we've added the code prior to qemu setting the interface in stone
and thus it will be changed incompatibly and we already have tests for
the new interface we need to update the code and qemu capabilities data
at the same time.

Use a array of bitmaps as the 'bitmaps' argument instead of 'bitmap' and
bump qemu capabilities for the upcoming 5.2.0 release to
v5.1.0-2827-g2c6605389c

b87cfc957f qemu: capabilities: Disable detection of QEMU_CAPS_BLOCK_EXPORT_ADD
We use the capability to switch to using 'block-export-add' in the
upcoming qemu release instead of the at the same time deprecated
'nbd-server-add'.

Unfortunately qemu wants to change the interface of 'block-export-add'
before the release. Since we've tried to stay up to date and added the
code before it was written in stone, we need to disable the use of the
new interface for the upcoming libvirt release so that we don't have a
version of libvirt which would not work with the upcoming qemu version.

Remove the detection of 'block-export-add' until we are more sure how
the qemu interface will look.

This patch partially reverts commit adb9f7123a

7b1ed1cd73 qemu: stop passing -enable-fips to QEMU >= 5.2.0
Use of the -enable-fips option is being deprecated in QEMU >= 5.2.0. If
FIPS compliance is required, QEMU must be built with libcrypt which will
unconditionally enforce it.

Thus there is no need for libvirt to pass -enable-fips to modern QEMU.
Unfortunately there was never any way to probe for -enable-fips in the
first instance, it was enabled by libvirt based on version number
originally, and then later unconditionally enabled when libvirt dropped
support for older QEMU. Similarly we now use a version number check to
decide when to stop passing -enable-fips.

Note that the qemu-5.2 capabilities are currently from the pre-release
version and will be updated once qemu-5.2 is released.

3b7ca6d419 qemu: capabilities: Introduce QEMU_CAPS_VIRTIO_BLK_SCSI_DEFAULT_DISABLED
Historically the 'scsi' passthrough feature of virtio-blk-pci
was enabled by default. Libvirt was disabling it due to security
implications outlined in libvirt commit v0.9.9-4-g177db08775 if it was
not explicitly requested. In qemu commit v2.4.0-1566-ged65fd1a27 the
default value was changed to disabled in preparation for virtio-1.
Starting from QEMU-5.0 the 'scsi' property was also deprecated. There
replacement for the functionality is to use 'virtio-scsi' for the
purpose. This isn't a direct replacement though.

Add capability named QEMU_CAPS_VIRTIO_BLK_SCSI_DEFAULT_DISABLED which
allows us to stop formatting the 'scsi=' property if it's disabled by
default and not requested so that we don't use deprecated features.

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.

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.
