The 'virDrvFeature' has a combination of features which are asserted by
the specific driver and features which are actually global.
In many cases the implementation was cargo-culted into newer drivers
without re-assesing whether it makes sense.
This patch introduces a global function which will specifically handle
these global flags and defer the rest to the driver.

The minimal supported version of QEMU is 2.11. And after capabilities
for older QEMUs were dropped in v7.3.0-17-g184de10c1d we have some

domaincapstest uses testQemuCapsIterate() which iterates over

Our code uses fdsets for the pipe passed from virtlogd to qemu, but the

we'll always prefix with a device alias or e.g. node name once fdsets

When starting a VM we must assign unique IDs for fdsets we add via
'-add-fd'. For now it was done by using the index of the filedescriptor
passed to the virCommand. That approach is not very flexible, because
you need to have already passed the 'fd' to virCommand before generating
the fdset path, and also won't nicely work with fdsets containing two or
more fds.

so that we can allocate unique ids without relying on virCommand.
