Arguments for driver entry points are checked in libvirt.c, so no need to
check again. Make function entry points consistent. Don't type caste the
privateData.

Currently the APIs for managing the shared disk list take
a virHashTablePtr as the primary argument. This is bad
because it requires the caller to deal with locking of
the QEMU driver. Switch the APIs to take the full
virQEMUDriverPtr instance

Add locking to virSecurityManagerXXX APIs, so that use of the
security drivers is internally serialized. This avoids the need
to rely on the global driver locks to achieve serialization

To enable locking to be introduced to the security manager
objects later, turn virSecurityManager into a virObjectLockable
class

Instead of creating an iptables command in one shot, do it in steps
so we can add conditional options like physdev and protocol.
This removes code duplication while keeping existing behaviour.

From qemu's point of view these are still just tap devices, so there's
no reason they shouldn't work with vhost-net; as a matter of fact,
Raja Sivaramakrishnan <srajag00@yahoo.com> verified on libvir-list
that at least the qemu_command.c part of this patch works:
https://www.redhat.com/archives/libvir-list/2012-December/msg01314.html
(the hotplug case is extrapolation on my part).
The 'driver->caps' pointer can be changed on the fly. Accessing
it currently requires the global driver lock. Isolate this
access in a single helper, so a future patch can relax the
locking constraints.

To avoid confusion between 'virCapsPtr' and 'qemuCapsPtr'
do some renaming of various fucntions/variables. All
instances of 'qemuCapsPtr' are renamed to 'qemuCaps'. To
avoid that clashing with the 'qemuCaps' typedef though,
rename the latter to virQEMUCaps.

To enable virCapabilities instances to be reference counted,
turn it into a virObject. All cases of virCapabilitiesFree
turn into virObjectUnref

The virCgroupPtr instance APIs are safe to use without locking
in the QEMU driver, since all internal state they rely on is
immutable. Update the comment to reflect this.

The data files for testing QEMU command line generation are
hardcoded to use /etc/pki, so we should explicitly set that
in the test case, avoiding the dynamic SYSCONFDIR value.

We are requesting for stderr catching for all cases in
virFileWrapperFdNew(). There is no need to have a separate
function just to report an error, esp. when we can do it in
virFileWrapperFdClose().
hacking: Add some text around the running of Valgrind along with example
output for "real" vs. "false positives".
cfg.mk: Add hacking.in.html to sc_prohibit_raw_allocation
When Valgrind runs the 'qemumonitorjsontest' it would claim that the
thread created is leaked. That's because the virThreadJoin won't get
called due to the 'running' flag being cleared. In order to avoid that,
call virThreadJoin unconditionally at cleanup time. Also noted that the
qemuMonitorTestWorker() didn't get the test mutex lock on the failure path.
The incoming and outgoing buffers allocated by qemuMonitorTestIO() and
qemuMonitorTestAddReponse() were never VIR_FREE()'d in qemuMonitorTestFree().
The 'package' string returned by qemuMonitorGetVersion() needs to
be VIR_FREE()'d.
testQemuMonitorJSONGetMachines(), testQemuMonitorJSONGetCPUDefinitions(),
and testQemuMonitorJSONGetCommands() did not VIR_FREE() the array and
array elements allocated by their respective qemuMonitorGet* routines.
The qemuParseGlusterString() replaced dst->src without a VIR_FREE() of
what was in there before.
The qemuBuildCommandLine() did not properly free the boot_buf depending
on various usages.
The qemuParseCommandLineDisk() had numerous paths that didn't clean up
the virDomainDiskDefPtr def properly. Adjust the logic to go through an
error: label before cleanup in order to free the resource.
Valgrind deterimined that fakeSecretGetValue() was using the secret
value without checking validity. Returning NULL causes the caller
to emit a message and results in failure.
Additionally commit 'b090aa7d' changes leaked vncSASLdir and vncTLSx509certdir
Commit 2025356 missed uses of PCI functions in the older HAL-related

The conditional setting of cmdout in networkBuildDhcpDaemonCommandLine()
caused Coverity to complain that 'cmd' could be leaked if !cmdout. Since
the function is local and only called with cmdout being passed those checks
have been removed.
