vnc: add support for listen type 'socket'
VNC graphics already supports sockets but only via 'socket' attribute.
This patch coverts that attribute into listen type 'socket'.
For backward compatibility we need to handle listen type 'socket' and 'socket'
attribute properly to support old XMLs and new XMLs. If both are provided they
have to match, if only one of them is provided we need to be able to parse that
configuration too.
To not break migration back to old libvirt if the socket is provided by user we
need to generate migratable XML without the listen element and use only 'socket'
attribute.

vnc: rename socketAutogenerated to socketFromConfig
Even though it's auto-generated it's based on qemu.conf option and listen type
address already uses "fromConfig" to carry this information. Following commits
will convert the socket to listen element so this rename is required because
there will be also an option to get socket auto-generated independently on the
qemu.conf option.
qemu: Generate channel target paths on hotplug as well
Since commit 714080791778e3dfbd484ccb3953bffd820b8ba9, qemu agent
channel cannot be plugged in because we won't generate its path
automatically. Let's not only fix that, but also add tests for it so
next time it's checked for.
Until now, the only hot thing in this test was the name. That's because
we set the id to '-1' before every test. With this change, we test the
hotplug on live domains as the name suggests and as it should be.

tests: Add CPU detection tests
So far we only test CPUID -> CPU def conversion on artificial CPUID data
computed from another CPU def. This patch adds the infrastructure to
test this conversion on real data gathered from a host CPU and two
helper scripts for adding new test data:
- cpu-gather.sh runs cpuid tool and qemu-system-x86_64 to get CPUID data
from the host CPU; this is what users can be asked to run if they run
into an issue with host CPU detection in libvirt
- cpu-parse.sh takes the data generated by cpu-gather.sh and creates
data files for CPU detection tests
The CPUID data queried from QEMU will eventually switch to the format
used by query-host-cpu QMP command once QEMU implements it. Until then
we just spawn QEMU with -cpu host and query the guest CPU in QOM. They
should both provide the same CPUID results, but query-host-cpu does not
require any guest CPU to be created by QEMU.

In Fedora >= 21, there is a new crypto priority framework
that sets TLS policies globally for all apps. To activate
this with GNUTLS we must request "@SYSTEM" instead of
the traditional "NORMAL" string. The '@' causes gnutls todo
a lookup in its config file for the 'SYSTEM' keyword entry.

Pass config file object through to driver open methods
The virConnectOpenInternal method opens the libvirt client
config file and uses it to resolve things like URI aliases.
There may be driver specific things that are useful to
store in the config file too, so rather than have them
re-parse the same file, pass the virConfPtr down to the
drivers.

Currently libvirt calls gnutls_set_default_priority()
which on old systems resolves to "NORMAL" while new
systems it resolves to "@SYSTEM". Either way, this
is a global default that is identical across all apps.
We want to allow distros to flexibility to define a
custom default string for libvirt priority, so add
a --tls-priority=STRING flag to configure to enable
this to be set.
It is expected that distros would use this when creating
RPM/Deb/etc packages, according to their preferred crypto
handling policies.
