7526a71586 conf: Keep 'readonly' property when resetting disk source
The property is necessary also for the disk using the source (e.g. cdrom)
which needs to be kept readonly.

Commit '462c4b66' was a bit too aggressive in this aspect, since the
readonly flag is set only while parsing.

bdcf6e4810 perf: get rid of pointless virPerfGetEvent() method
The virPerfGetEvent method pointlessly checks for a NULL
parameter and the range of an enum value. The whole point
of using an enum is that we can avoid such checks. Just
replace calls to virPerfGetEvent, with perf->events[type]
array access.

c8a637c7d0 virsh: add helpers for getting domain XML for XPath purposes
In virsh we quite often get the domain XML just to initialize the XPath
parser so that we can extract information.

Add helpers which will simplify this by wrapping the getting of the XML
and parsing it along with error reporting.

Additionally a second helper also gets the domain object from the
parameters and releases it so that functions which need the XML as only
source of data can be simplified further.

b4c2ac8d56 qemu: Fix mdev checking for VFIO support
Commit a4a39d90 added a check that checks for VFIO support with mediated
devices. The problem is that the hostdev preparing functions behave like
a fallthrough if device of that specific type doesn't exist. However,
the check for VFIO support was independent of the existence of a mdev
device which caused the guest to fail to start with any device to be
directly assigned if VFIO was disabled/unavailable in the kernel.
The proposed change first ensures that it makes sense to check for VFIO
support in the first place, and only then performs the VFIO support check
itself.
