Well, even though users can pass the list of UEFI:NVRAM pairs at the
configure time, we may maintain the list of widely available UEFI
ourselves too. And as arm64 begin to rises, OVMF was ported there too.
With a slight name change - it's called AAVMF, with AAVMF_CODE.fd
being the UEFI firmware and AAVMF_VARS.fd being the NVRAM store file.

Up until now there are just two ways how to specify UEFI paths to
libvirt. The first one is editing qemu.conf, the other is editing
qemu_conf.c and recompile which is not that fancy. So, new
configure option is introduced: --with-loader-nvram which takes a
list of pairs of UEFI firmware and NVRAM store. This way, the
compiled in defaults can be passed during compile time without
need to change the code itself.

The function may return NULL if something went wrong. In some places
in the tests we are not checking the return value rather than
accessing the pointer directly resulting in SIGSEGV.

Commit f05b6a91 added virQEMUDriverConfigPtr argument to the
virQEMUCapsFillDomainCaps function and it uses forward declaration
of virQEMUDriverConfig and virQEMUDriverConfigPtr that casues clang
build to fail:
gmake[3]: Entering directory `/usr/home/novel/code/libvirt/src'

Fix that by passing loader and nloader config attributes directly
instead of passing complete config.
As of f05b6a918e the test produces the list of paths that can
be passed to <loader/> and libvirt knows about them. However,
during the process of generating the list the paths are checked
for their presence. This may produce different results on
different systems. Therefore, the path - if missing - is
added to pretend it's there.

Check to see if the UEFI binary mentioned in qemu.conf actually
exists, and if so expose it in domcapabilities like
<loader ...>
<value>/path/to/ovmf</value>
</loader>
We introduce some generic domcaps infrastructure for handling
a dynamic list of string values, it may be of use for future bits.

Up till now the virQEMUCapsFillDomainCaps() was type of void as
there was no way for it to fail. This is, however, going to
change in the next commit.

As of 542899168c we learned libvirt to use UEFI for domains.
However, management applications may firstly query if libvirt
supports it. And this is where virConnectGetDomainCapabilities()
API comes handy.

So far only information on disks and host devices are exposed in the
capabilities XML. Well, at least something. Even a new test is
introduced. The qemu capabilities are stolen from already existing
qemucapabilities test. There's one tricky point though. Functions that
checks host's KVM and VFIO capabilities, are impossible to mock
currently. So in the test, we are setting the capabilities by hand.

This new module holds and formats capabilities for emulator. If you
are about to create a new domain, you may want to know what is the
host or hypervisor capable of. To make sure we don't regress on the
XML, the formatting is not something left for each driver to
implement, rather there's general format function.
The domain capabilities is a lockable object (even though the locking
is not necessary yet) which uses reference counter.
