f6d4405e3c Convert (nearly) all files in src/util/ to use virReportError()
This removes nearly all the per-file error reporting macros
from the code in src/util/. A few custom macros remain for the
case, where the file needs to report errors with a variety of
different codes or parameters

7e94acd4fc Introduce virReportError macro for general error reporting
Nearly every source file does something like

  #define VIR_FROM_THIS VIR_FROM_FOO
  #define virFooReportErorr(code, ...) \
     virReportErrorHelper(VIR_FROM_THIS, code,  __FILE__,    \
                          __FUNCTION__, __LINE__, \
                          __VA_ARGS__)

This creates needless duplication and inconsistent error
reporting function names in each file. It is trivial to
just have virterror_internal.h provide a virReportError
macro that is equivalent

* src/util/virterror_internal.h: Define virReportError(code, ...)

17f3be079c remote: Fix locking in stream APIs
Remote driver needs to make sure the driver lock is released before
entering client IO loop as that may block indefinitely in poll(). As a
direct consequence of not following this in stream APIs, tunneled
migration to a destination host which becomes non-responding may block
qemu driver. Luckily, if keepalive is turned for p2p migrations, both
remote and qemu drivers will get automagically unblocked after keepalive
timeout.

then replace raw MAC addresses by replacing

and introduce usage of above functions where necessary.

8e6fb68f1f qemu: Fix probing for guest capabilities
Even though qemu-kvm binaries can be used in TCG mode, libvirt would
only detect them if /dev/kvm was available. Thus, one would need to make
a /usr/bin/qemu symlink to be able to use TCG mode with qemu-kvm in an
environment without KVM support.

And even though QEMU is able to make use of KVM, libvirt would not
advertise KVM support unless there was a qemu-kvm symlink available.

This patch fixes both issues.

3189dfb163 Clarify direct migration

that does not support direct migration (such as QEMU), the caller would
get the following error message:

    this function is not supported by the connection driver:
    virDomainMigrateToURI2

which is a complete nonsense since qemu driver implements
virDomainMigrateToURI2. This patch would emit a more sensible error in
this case:

    Requested operation is not valid: direct migration is not supported
    by the connection driver

efe6c80211 Fix daemon auto-spawning
Commit 32a9aac switched libvirt to use the XDG base directories
to locate most of its data/config. In particular, the per-user socket
for qemu:///session is now stored in the XDG runtime directory.
This directory is located by looking at the XDG_RUNTIME_DIR environment
variable, with a fallback to ~/.cache/libvirt if this variable is not
set.

When the daemon is autospawned because a client application wants
to use qemu:///session, the daemon is ran in a clean environment
which does not contain XDG_RUNTIME_DIR. It will create its socket
in ~/.cache/libvirt. If the client application has XDG_RUNTIME_DIR
set, it will not look for the socket in the fallback place, and will
fail to connect to the autospawned daemon.

This patch adds XDG_RUNTIME_DIR to the daemon environment before
auto-starting it. I've done this in virNetSocketForkDaemon rather
than in virCommandAddEnvPassCommon as I wasn't sure we want to pass
these variables to other commands libvirt spawns. XDG_CACHE_HOME
and XDG_CONFIG_HOME are also added to the daemon env as it makes use
of those as well.

1ffc78b54b Support creation of sparse LVM volumes
When calling 'lvcreate' if specifying both the '-L' and
'--virtualsize' options, the latter will be treated as
the capacity and the former as the allocation. This can
be used to support sparse volume creation. In addition,
when listing volumes it is necessary to include the 'size'
field in lvs output, so that we can detect sparse volume
allocation correctly.

80533ca25d nodeinfo: Fix gathering of nodeinfo data structure
This patch changes the way data to fill the nodeinfo structure are
gathered. We've gathere the test data by iterating processors an sockets
separately from nodes. The reported data was based solely on information
about core id. Problems arise when eg cores in mulit-processor machines
don't have same id's on both processors or maybe one physical processor
contains more NUMA nodes.

This patch changes the approach how we detect processors and nodes. Now
we start at enumerating nodes and for each node processors, sockets and
threads are enumerated separately. This approach provides acurate data
that comply to docs about the nodeinfo structure. This also enables to
get rid of hacks: see commits 10d9038b74,
ac9dd4a676. (Those changes in nodeinfo.c
are efectively reverted by this patch).

This patch also changes output of one of the tests, as the processor
topology is now acquired more precisely.

f5dd58a608 qemu: Extended qemuDomainAssignAddresses to be callable from everywhere.
This is in preparation of the enablement of s390 guests with virtio devices.

The assignment of device addresses happens in different places, i.e. the
qemu driver and process modules as well as in the unit tests in slightly
different flavors. Currently, these are PPC spapr-vio and PCI
devices, virtio-s390 (not PCI based) will follow.

By optionally passing to qemuDomainAssignAddresses the domain
object and the capabilities it is now possible to call the function
from most of the places (except for hotplug) where address assignment
is done.

626dd5180e Fix /domain/features setting in qemuParseCommandLine
Commit 5e6ce1 moved down detection of the ACPI feature in
qemuParseCommandLine. However, when ACPI is detected, it clears
all feature flags in def->features to only set ACPI. This used to
be fine because this was the first place were def->features was set,
but after the move this is no longer necessarily true because this
block comes before the ACPI check:

if (strstr(def->emulator, "kvm")) {
    def->virtType = VIR_DOMAIN_VIRT_KVM;
    def->features |= (1 << VIR_DOMAIN_FEATURE_PAE);
}

Since def is allocated in qemuParseCommandLine using VIR_ALLOC, we
can always use |= when modifying def->features
