This function needs domain definition really, we don't need to
pass the whole domain object. This saves couple of dereferences
and characters esp. in more checks to come.

Now that we no longer use any of the macros from this file, remove it.
This also removes a typo.

Since commit 44e7f02915
util: rewrite auto cleanup macros to use glib's equivalent
VIR_AUTOPTR aliases to g_autoptr. Replace all uses of VIR_DEFINE_AUTOPTR_FUNC
with G_DEFINE_AUTOPTR_CLEANUP_FUNC in preparation for replacing the
rest.

The qemuFirmwareGetSupported() function is called from qemu
driver to generate domain capabilities XML based on FW descriptor
files. However, the function currently reports only some features
from domcapabilities XML and not actual FW image paths. The paths
reported in the domcapabilities XML are still from pre-FW
descriptor era and therefore the XML might be a bit confusing.
For instance, it may say that secure boot is supported but
secboot enabled FW is not in the listed FW image paths.
To resolve this problem, change qemuFirmwareGetSupported() so
that it also returns a list of FW images (we have the list
anyway). Luckily, we already have a structure to represent a FW
image - virFirmware.

The point of this API is to fetch all FW descriptors, parse them
and return list of supported interfaces and SMM feature for given
combination of machine type and guest architecture.

'viralloc.h' does not provide any type or macro which would be necessary
in headers. Prevent leakage of the inclusion.

Keeping them with viralloc.h forcibly pulls in the other stuff from
viralloc.h into other header files. This in turn creates a mess
as more and more headers pull in the 'viral' header file.
If we want to make 'viralloc.h' omnipresent we should pick a different
approach.

And finally the last missing piece. This is what puts it all
together.
At the beginning, qemuFirmwareFillDomain() loads all possible
firmware description files based on algorithm described earlier.
Then it tries to find description which matches given domain.
The criteria are:
- firmware is the right type (e.g. it's bios when bios was
requested in domain XML)
- firmware is suitable for guest architecture/machine type
- firmware allows desired guest features to stay enabled (e.g.
if s3/s4 is enabled for guest then firmware has to support
it too)
Once the desired description has been found it is then used to
set various bits of virDomainDef so that proper qemu cmd line is
constructed as demanded by the description file. For instance,
secure boot enabled firmware might request SMM -> it will be
enabled if needed.

Implementation for yet another part of firmware description
specification. This one covers selecting which files to parse.
There are three locations from which description files can be
loaded. In order of preference, from most generic to most
specific these are:
/usr/share/qemu/firmware
/etc/qemu/firmware
$XDG_CONFIG_HOME/qemu/firmware
If a file is found in two or more locations then the most specific
one is used. Moreover, if file is empty then it means it is
overriding some generic description and disabling it.
Again, this is described in more details and with nice examples
in firmware.json specification (qemu commit 3a0adfc9bf).
However, there's one slight difference - for the root user the
home directory is not searched. This follows rules laid out by
similar look up processes, e.g. PKI x509 certs are not searched
in /root but they are looked for under /home.

The firmware description is a JSON file which follows
specification from qemu.git/docs/interop/firmware.json. The
description file basically says: Firmware file X is {bios|uefi},
supports these targets and machine types, requires these features
to be enabled on qemu cmd line and this is how you put it onto
qemu cmd line.
The firmware.json specification covers more (i.e. how to select
the right firmware) but that will be covered and implemented in
next commits.
