b0f0e96cdd qemu: capabilities: add QEMU_CAPS_FSDEV_CREATEMODE
The QEMU 9pfs 'fmode' and 'dmode' options have existed since QEMU 2.10.
Probe QEMU's command line set to check whether these options are
available, and if yes, enable this new QEMU_CAPS_FSDEV_CREATEMODE
capability on libvirt side.

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.

9ce32b0935 qemu: Introduce fw_cfg capability
This capability tracks whether QEMU supports -fw_cfg command line
option, more specifically whether it allows specifying filename.

There are some releases of QEMU which support -fw_cfg but not
filename. If this is ever a problem we can refine the capability
later on.

e7a65484ba qemu: Refuse to use "ps2" on machines that do not have this bus
The "ps2" bus is only available on certain machines like x86. On
machines like s390x, we should refuse to add a device to this bus
instead of silently ignoring it.

Looking at the QEMU sources, PS/2 is only available if the QEMU binary
has the "i8042" device, so let's check for that and only allow "ps2"
devices if this QEMU device is available, or if we're on x86 anyway
(so we don't have to fake the QEMU_CAPS_DEVICE_I8042 capability in
all the tests that use <input ... bus='ps2'/> in their xml data).

c4d6465aa7 tests: testQemuCapsIterate: Pass prefix and version to callback
Right now we're passing a "base" string that contains both,
separated by an underscore. Some changes that we're going to
introduce later will require us to have the version number on its
own, and instead of delegating the task of splitting the two apart
to the callback it make more sense to perform it upfront.

This change results in quite a bit of churn because we're now
using the version number only, without the prefix, to calculate
the dummy microcodeVersion.
