The virCapabilitiesDomainDataLookupInternal() is given a list of
parameters representing the desired domain characteristics. It then has
to look throught the capabilities to identify an acceptable match.

The virCapsDomainDataCompare() method is used for filtering out
candidates which don't match the desired criteria. It is called
primarily from the innermost loops and as such is doing many repeated
checks. For example if architcture and os type were checked at the top
level loop the two inner loops could be avoided entirely. If emulator
and domain type were checked in the 2nd level loop the 3rd level loop
can be avoided too.

This change thus removes the virCapsDomainDataCompare() method and puts
suitable checks at the start of each loop to ensure it executes the
minimal number of loop iterations possible. The code becomes clearer to
understand as a nice side-effect.

Fix regression introduced in <42fd5a58>. With q35 machine type which
requires the explicitly specified FDC we'd format twoisa-fdc
controllers to the command line as the code was moved to a place where
it's called per-disk.

Move the call back after formatting all disks and reiterate the disks to
find the floppy controllers.

This also moves the '-global' directive which sets up the default
ISA-FDC to the end after all the disks but since we are modifying the
properties it is safe to do so.

It is increasingly likely that some distro is going to change the
default "x86" machine type in QEMU from "pc" to "q35". This will
certainly break existing applications which write their XML on the
assumption that it is using a "pc" machine by default. For example they'll
lack a IDE CDROM and get PCIe instead of PCI which changes the topology
radically.

Libvirt promises to isolate applications from hypervisor changes that
may cause incompatibilities, so we must ensure that we always use the
"pc" machine type if it is available. Only use QEMU's own reported
default machine type if "pc" does not exist.

This issue is not x86-only, other arches are liable to change their
default machine, while some arches don't report any default at all
causing libvirt to pick the first machine in the list. Thus to
guarantee stability to applications, declare a preferred default
machine for all architectures we currently support with QEMU.

Note this change assumes there will always be a "pc" alias as long as a
versioned "pc-XXX" machine type exists. If QEMU were to ship a "pc-XXX"
machine type but not provide the "pc" alias, it is too hard to decide
which to default so. Versioned machine types are supposed to be
considered opaque strings, so we can't apply any sensible ordering
ourselves and QEMU isn't reporting the list of machines in any sensible
ordering itself.
