The code preparing data for creating/attaching the target image of block

Since libvirt stores the backing chain into the XML in a nested way it
is the prime possibility to hit libxml2's parsing limit of 256 layers.
Introduce code which will crawl the backing chain and verify that it's
not too deep. The maximum nesting is set to 200 layers so that there's
still some space left for additional properties or nesting into snapshot
XMLs.
The check is applied to all disk use cases (starting, hotplug, media
change) as well as block copy which changes image and snapshots.
We simply report an error and refuse the operation.
Without this check a restart of libvirtd would result in the status XML
failing to be parsed and thus losing the VM.

Since version 3.0, qemu has returned disk usage statistics in
guest-get-fsinfo. And since 3.1, it has returned information about the
disk serial number and device node of disks that are targeted by the
filesystem.
Unfortunately, the public API virDomainGetFSInfo() returns the
filesystem info using a virDomainFSInfo struct, and due to API/ABI
guarantees it cannot be extended. So this new information cannot
easily be added to the public API. However, it is possible to add this
new filesystem information to a new virDomainGetGuestInfo() API which
will be based on typed parameters and is thus more extensible.
In order to support these two use cases, I added an internal struct
which the agent code uses to return all of the new data fields. This
internal struct can be converted to the public struct at a cost of some
extra memory allocation.
In a following commit, this additional information will be used within
virDomainGetGuestInfo().

QEMU finally exposes an interface which allows us to instruct it to
format or create arbitrary images. This is required for blockdev
integration of block copy and snapshots as we need to pre-format images
prior to use with blockdev-add.
This path introduces job handling and also helpers for formatting and
attaching a whole image described by a virStorageSource.

The utility of the function is extremely limited as for block copy

Back in July 2010, commit 6ea90b84 (meant to resolve
https://bugzilla.redhat.com/571991 ) added code to set the MAC address
of any tap device to the associated guest interface's MAC, but with
the first byte replaced with 0xFE. This was done in order to assure
that
1) the tap MAC and guest interface MAC were different (otherwise L2
forwarding through the tap would not work, and the kernel would
repeatedly issue a warning stating as much).
2) any bridge device that had one of these taps attached would *not*
take on the MAC of the tap (leading to network instability as
guests started and stopped)
A couple years later, https://bugzilla.redhat.com/798467 was filed,
complaining that a user could configure a tap-based guest interface to
have a MAC address that itself had a first byte of 0xFE, silently
(other than the kernel warning messages) resulting in a non-working
configuration. This was fixed by commit 5d571045, which logged an
error and failed the guest start / interface attach if the MAC's first
byte was 0xFE.
Although this restriction only reduces the potential pool of MAC
addresses from 2^46 (last two bits of byte 1 must be set to 10) by
2^32 (still 4 orders of magnitude larger than the entire IPv4 address
space), it also means that management software that autogenerates MAC
addresses must have special code to avoid an 0xFE prefix. Now after 7
years, someone has noticed this restriction and requested that we
remove it.
So instead of failing when 0xFE is found as the first byte, this patch
removes the restriction by just replacing the first byte in the tap
device MAC with 0xFA if the first byte in the guest interface is
0xFE. 0xFA is the next-highest value that still has 10 as the lowest
two bits, and still
2) meets the requirement of "tap MAC must be different from guest
interface MAC", and
3) is high enough that there should never be an issue of the attached
bridge device taking on the MAC of the tap.
The result is that *any* MAC can be chosen by management software
(although it would still not work correctly if a multicast MAC (lowest
bit of first byte set to 1) was chosen), but that's a different
issue).

Upcoming patches want to use the domCaps data store at XML validate
time, but we need to cache the data so we aren't repeatedly
regenerating it.
Add a domCapsCache hash table to qemuCaps. This ensures that the domCaps
cache is blown away whenever qemuCaps needs to be regenerated. Similarly
when qemuCaps is invalidated, the next call to virQEMUCapsCacheLookup
