We provide a custom configure option --enable-test-coverage and
'make cov' target to generate code coverage reports. However gnulib
already provides a 'make coverage' which 'just works' and doesn't
require a special configure option.

This drops our custom implementation in favor of 'make coverage'.
Reports are now output to cov/index.html

The code tries to detect installed version of qemu to learn if it
uses HMP or QMP and enable YAJL based on that. Well, we support
only QMP and also minimal required version of qemu is 1.5.0 so
the check would have enabled yajl anyway.

Apparently this was necessary in the past because old versions

xenbus is virtual controller (akin to virtio controllers) for Xen
paravirtual devices. Although all Xen VMs have a xenbus, it has
never been modeled in libvirt, or in Xen native VM config format
for that matter.

Recently there have been requests to support Xen's max_grant_frames
setting in libvirt. max_grant_frames is best modeled as an attribute
of xenbus. It describes the maximum IO buffer space (or DMA space)
available in xenbus for use by connected paravirtual devices. This
patch introduces a new xenbus controller type that includes a
maxGrantFrames attribute.

Commit a3ab6d42 changed the libvirtd profile to a named profile,
breaking the apparmor driver's ability to detect if the profile is
active. When the apparmor driver loads it checks the status of the
libvirtd profile using the full binary path, which fails since the
profile is now referenced by name. If the apparmor driver is
explicitly requested in /etc/libvirt/qemu.conf, then libvirtd fails
to load too.

Instead of only checking the profile status by full binary path,
also check by profile name. The full path check is retained in case
users have a customized libvirtd profile with full path.
