4808323994 qemu: capabilities: Un-retire QEMU_CAPS_EGL_HEADLESS
egl-headless graphics can be compiled out in qemu so we need to be able
to know whether the given qemu version support it.

Base the capability on the presence of the 'egl-headless' member in
'query-display-options' or imply it if 'query-display-options' is not
supported as we implied it before for all versions.

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.

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.
