qemu: command: Don't format -device isa-fdc,... twice with two floppy drives
Fix regression introduced in <42fd5a58adb>. 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.

qemu: ensure default machine types don't change if QEMU changes
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.

util: netdevvlan: define cleanup function using VIR_DEFINE_AUTOPTR_FUNC
Using the new VIR_DEFINE_AUTOPTR_FUNC macro defined in
src/util/viralloc.h, define a new wrapper around an existing
cleanup function which will be called when a variable declared
with VIR_AUTOPTR macro goes out of scope. Also, drop the redundant
viralloc.h include, since that has moved from the source module into
the header.
When a variable of type virNetDevVlanPtr is declared using
VIR_AUTOPTR, the function virNetDevVlanFree will be run
automatically on it when it goes out of scope.
