628e343e79 docs: use overpass font for website
The original libvirt logo was built using what appears to be
either Overpass font, or one stylistically very similar (the
slanted top of letters like 'l', 't', etc). The newly recreated
libvirt logo will use Overpass. Use this font for the website
text too, to provide a consistent style.

b7798a07f9 qemu: Generate memory device aliases according to slot number
The memory device alias needs to be treated as machine ABI as qemu is
using it in the migration stream for section labels. To simplify this
generate the alias from the slot number unless an existing broken
configuration is detected.

With this patch the aliases are predictable and even certain
configurations which would not be migratable previously are fixed.

ce1ee02a25 qemu: Assign slots to memory devices prior to usage
As with other devices assign the slot number right away when adding the
device. This will make the slot numbers static as we do with other
addressing elements and it will ultimately simplify allocation of the
alias in a static way which does not break with qemu.

93d9ff3da0 qemu: process: detect if dimm aliases are broken on reconnect
Detect on reconnect to a running qemu VM whether the alias of a
hotpluggable memory device (dimm) does not match the dimm slot number
where it's connected to. This is necessary as qemu is actually
considering the alias as machine ABI used to connect the backend object
to the dimm device.

This will require us to keep them consistent so that we can reliably
restore them on migration. In some situations it was currently possible
to create a mismatched configuration and qemu would refuse to restore
the migration stream.

To avoid breaking existing VMs we'll need to keep the old algorithm
though.

810e9a8061 conf: Allow specifying only the slot number for hotpluggable memory

a944bd9259 qemu: conf: add option for tuning debug logging level
This helps in selecting log level of the gluster gfapi, output to stderr.
The option is 'gluster_debug_level', can be tuned by editing
'/etc/libvirt/qemu.conf'

Debug levels ranges 0-9, with 9 being the most verbose, and 0
representing no debugging output.  The default is the same as it was
before, which is a level of 4.  The current logging levels defined in
the gluster gfapi are:

    0 - None
    1 - Emergency
    2 - Alert
    3 - Critical
    4 - Error
    5 - Warning
    6 - Notice
    7 - Info
    8 - Debug
    9 - Trace

36e9b16e24 tests: qemucaps: Add QMP introspection data for qemu 2.6.0 on aarch64 gicv3
Add QMP schema data query for aarch64. The gic capabilities are
unfortunately queried after the QMP schema and thus this patch needs to
undo the temporary removal of the declared support for query-qmp-schema.

Note that as a gicv3 machine was not available the schema data is taken
from the gicv2 case. It should be identical since qemu would be built
from the same source.

70c7025d3b qemu: capabilities: Add support for QMP schema introspection
Allow detecting capabilities according to the qemu QMP schema. This is
necessary as sometimes the availability of certain options depends on
the presence of a field in the schema.

This patch adds support for loading the QMP schema when detecting qemu
capabilities and adds a very simple query language to allow traversing
the schema and selecting a certain element from it.

The infrastructure in this patch uses a query path to set a specific
capability flag according to the availability of the given element in
the schema.

This will be later reverted and test data will be added. The aarch64
code is special as it calls additional commands and thus the test data
can't be added upfront.

when srcdir != builddir we end up including libvirt-common.h twice: from
$top_srcdir/include/libvirt-common.h and from
$builddir/include/libvirt-common.h leading to

  function virTypedParamsGetUInt from /tmp/buildd/libvirt-2.4.0/debian/build/docs/../include/libvirt/libvirt-common.h redeclared in /tmp/buildd/libvirt-2.4.0/docs/../include/libvirt/libvirt-common.h

   …

Only add the builddir to the search list if there is no pregenerated
libvirt-common.h.

Reuse the existing check that predates the libvirt.h → libvirt-common.h
split and that probably was meant for exactly that.

7b3b254063 wireshark: Use ${exec_prefix} instead of ${prefix}
${exec_prefix} and ${prefix} point to the same directory in
most setups, but when that's not the case the former should
be used for architecture-dependent data such as shared objects,
which makes it the best fit for our Wireshark dissector.

While at it, change all uses of $(var) to ${var}: they are
absolutely identicaly as far as make's concerned, but autoconf
