All currently supported qemu versions support all throttling
capabilities. It is unlikely that any of the fields will be removed in
the future and if it will we will need to do specific probing which is
possible via the 'throttle' object which is the replacement for the
legacy way to configure throttling.

Add a cross reference of the enum value name with the string
representation. This allows a quick cross-reference of the values
without having to open the header and implementation files separately.
To achieve this the checker code at first obtains a list of the
flags and cross-references them when checking the grouping in
syntax-check, thus we are guaranteed to stay in sync.

Libvirt assumes that a SCSI bus can fit up to 8 devices
(including controller itself), except for so called wide bus
which can accommodate up to 16 devices (again, including
controller). This plays important role when computing 'drive'
address in virDomainDiskDefAssignAddress(). So far, the only
driver that enables wide SCSI bus is VMX. But with newer
releases, ESX is capable of "super wide" bus (64 devices).
We can blindly bump the limit in our code because then we would
compute address that's invalid for older ESX versions that we
still want to support.
Unfortunately, I haven't found a better place where to store this
than virDomainDef.

The way we parse VMX configuration is rather unfortunate,
especially when it comes to disks. We allocate an array that can
handle all possible disks but leave the array counter (ndisks) at
zero and increase it only after successful parsing. But, we never
size the array down to release unneeded chunks of memory.
We can do better: we can use VIR_APPEND_ELEMENT() to allocate
array as needed.

If the QEMU driver is configured to use the old "file" stdio
handler (meaning virtlogd is out of the picture) and a chardev
has a log file configured we rely on QEMU being able to create
the file itself. This may not be always possible (e.g. if the
logfile is set to a directory that QEMU process can't reach).
In such case we should create the file and just pass its FD to
QEMU.
We could do that unconditionally and just either pass FD from
virtlogd or the one we opened, because we bumped QEMU version
and are now requiring new enough QEMU. However, I'm keeping the
old style where logfile is appended on the cmd line for the tests
sake.
