cc5311e730 systemd: honour $runstatedir in socket unit files
If a systemd socket uses /var/run in its path, systemd prints a warning
at runtime

[   15.139976] systemd[1]: /usr/lib/systemd/system/virtlockd.socket:5:
  ListenStream= references a path below legacy directory /var/run/,
  updating /var/run/libvirt/virtlockd-sock → /run/libvirt/virtlockd-sock;
  please update the unit file accordingly.

This minimal change updates the socket unit files to honour the
$runstatedir path.

There's no functional change by default yet since both expressions
expand to the same value.

5f449aea19 remote: conditionalize IP socket config in augeas definitions
Prepare for reusing libvirtd augeas defintions with other daemons by
making the config parameters for IP sockets conditionally defined by
the make rules.

6d9e520db6 remote: conditionalize IP socket config in libvirtd.conf
Prepare for reusing libvirtd config to create other daemons by making
the config parameters for IP sockets conditionally defined by the make
rules.

The main libvirtd daemon will retain IP listen ability, but all the
driver specific daemons will be local UNIX sockets only. Apps needing
IP connectivity will connect via the libvirtd daemon which will proxy
to the driver specfic daemon.

697371c22e build: use @CONFIG@ instead of ::CONFIG:: in augeas tests
Using @VARNAME@ is a normal style of automake, so lets match that.

5a148ce846 remote: delete the avahi mDNS support
Libvirtd has long had integration with avahi for advertising libvirtd
using mDNS when TCP/TLS listening is enabled. For a long time the
virt-manager application had support for auto-detecting libvirtds
on the local network using mDNS, but this was removed last year

  commit fc8f8d5d7e3ba80a0771df19cf20e84a05ed2422
  Author: Cole Robinson <crobinso@redhat.com>

    connect: Drop avahi support

    Libvirtd can advertise itself over avahi. The feature is disabled by
    default though and in practice I hear of no one actually using it
    and frankly I don't think it's all that useful

    The 'Open Connection' wizard has a disproportionate amount of code
    devoted to this feature, but I don't think it's useful or worth
    maintaining, so let's drop it

I've never heard of any other applications having support for using
mDNS to detect libvirtd instances. Though it is theoretically possible
something exists out there, it is clearly going to be a niche use case
in the virt ecosystem as a whole.

By removing avahi integration we can cut down the dependency chain for
the basic libvirtd install and reduce our code maint burden.

8ccee910f5 log: update docs for daemons to improve user understanding
Strongly recommend against use of the log_levels setting since it
creates overly verbose logs and has a serious performance impact.

Describe the log filter syntax better and mention use of shell
glob syntax. Also provide more realistic example of good settings
to use. The libvirtd example is biased towards QEMU, but when the
drivers split off each daemon can get its own more appropriate
example.

65824a7e45 rpc: remove remains of obsolete log_buffer_size config parameter
The global log buffer feature was deleted in:

  commit c0c8c1d7bb
  Author: Daniel P. Berrange <berrange@redhat.com>
  Date:   Mon Mar 3 14:54:33 2014 +0000

    Remove global log buffer feature entirely

    A earlier commit changed the global log buffer so that it only
    records messages that are explicitly requested via the log
    filters setting. This removes the performance burden, and
    improves the signal/noise ratio for messages in the global
    buffer. At the same time though, it is somewhat pointless, since
    all the recorded log messages are already going to be sent to an
    explicit log output like syslog, stderr or the journal. The
    global log buffer is thus just duplicating this data on stderr
    upon crash.

    The log_buffer_size config parameter is left in the augeas
    lens to prevent breakage for users on upgrade. It is however
    completely ignored hereafter.

This was in the 1.2.3 release, and 4 years is sufficient time for a
graceful upgrade path for augeas, so all remaining traces are now
removed.
