Daniel P. Berrangé f0fd90d722 conf: avoid reporting errors when network driver is disabled
In previous releases all these methods were a no-op if the network
driver is disabled. These helper methods are called unconditionally for
all types of network interface, so must be no-ops if missing. Other code
will already generate an error if the network driver is disabled and a
NIC with type=network is used.

Daniel P. Berrangé da1ade7a52 remote: remove some __sun conditionals
The libvirtd daemon has some arbitrary logic to drop privileges, but
only on Solaris platforms. This was added during Xen days, when Xen was
the only driver running in libvirtd. There's no expectation or testing
that this works with the new libxl stack, nor whether dropping
privileges breaks any of the secondary drivers. Finally, we'll be
splitting drivers out into their own independant daemons, so this won't
be applicable to libvirtd in future anyway.

The remote driver client meanwhile arbitrarily disables daemon
auto-spawn when connecting as non-root, breaking a key feature of
libvirt unprivileged connections.

Since we've not had any contributions for Solaris since circa 2012
and we don't do any CI testing we should consider this platform
unmaintained and thus reasonable to remove this cruft. If someone steps
forward to maintain Solaris again, this code would need re-evaluating to
come up with something more targetted.

There's various __sun conditionals in the Xen driver code, but those are
not touched. This is all for the legacy Xen driver, which will be
entirely removed at some point in future, so not benefit to hacking out
just the Solaris parts.

Similarly to b133fac356 we need to look up alias of CCID
controller when constructing smartcard command line instead of
relying on broken assumption it will always be 'ccid0'. After
user aliases it can be anything.

Most of the augeas test files use ::CONFIG:: to pull in the master
config file for testing. This ensures that entries added to the config
file are actually tested by augeas.

This identified the missing admin_max_clients example in the virtlogd
config file, which in turn prompted a change in description of the
max_clients parameter, since these daemons don't have separate
readonly & readwrite sockets.

Daniel P. Berrangé 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.

    Signed-off-by: Daniel P. Berrange <berrange@redhat.com>

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.

virt-aa-helper: generate rules for nvdimm memory

    <target>
     <size unit='KiB'>524288</size>

Jim Fehlig 83edaf4435 libxl: don't hardcode scheduler weight
Long ago in commit dfa1e1dd53 the scheduler weight was accidentally
hardcoded to 1000. Weight is a setting with no unit since it is
relative to the weight of other domains. If no weight is specified,
libxl defaults to 256.

Instead of hardcoding the weight to 1000, honor any <shares> specified
in <cputune>. libvirt's notion of shares is synonomous to libxl's
scheduler weight setting. If shares is unspecified, defer default
weight setting to libxl.

Removing the hardcoded weight required some test fixup. While at it,
add an explicit test for <shares> conversion to scheduler weight.
