The virLibConnError macros in libvirt-lxc.c and
libvirt-qemu.c were passing NULL for the filename.
This causes a crash if the logging code is configured
to use journald.

The shutdown test utilizes waiting for condition to exit the test. This
addition will return an error for the shutdown command to see if the
condition waiting code will not hang.
Coverity complained about unused variable that contains the shutdown
mode. The original intention was to check it against the requested mode.
Also the fixed check revealed a mistake in the expected shutdown mode.

* Move platform specific things (e.g. firewalling and route
collision checks) into bridge_driver_platform
* Create two platform specific implementations:
- bridge_driver_linux: Linux implementation using iptables,
it's actually the code moved from bridge_driver.c
- bridge_driver_nop: dumb implementation that does nothing

When building libvirt with -O0 flag in fedora 19, it will fail to
generate qemuagenttest, a link error occurs like:
./.libs/libqemumonitortestutils.a(qemumonitortestutils.o): In function `qemuMonitorTestFree':
libvirt/tests/qemumonitortestutils.c:346: undefined reference to `qemuMonitorClose'
./.libs/libqemumonitortestutils.a(qemumonitortestutils.o): In function `qemuMonitorTestNew':
libvirt/tests/qemumonitortestutils.c:870: undefined reference to `qemuMonitorOpen'
collect2: error: ld returned 1 exit status
Fix it by listing libraries in the correct order to avoid lazy linkage.

*src/util/virstoragefile.c: Add a helper function to get
the first name of missing backing files, if the name is NULL,
it means the diskchain is not broken.
*src/qemu/qemu_domain.c: qemuDiskChainCheckBroken(disk) to
check if its chain is broken
Refactor this function to make it focus on disk presence checking,
including diskchain checking, and not only for CDROM and Floppy.
This change is good for the following patches.
The virDomainDef is allocated by the caller and also used after
calling to xenDaemonCreateXML. So it must not get freed by the
callee.

Make the virCgroupNewMachine method try to use systemd-machined
first. If that fails, then fallback to using the traditional
cgroup setup code path.

When systemd is involved in managing processes, it may start
killing off & tearing down croups associated with the process
while we're still doing virCgroupKillPainfully. We must
explicitly check for ENOENT and treat it as if we had finished
killing processes

Systemd uses a named cgroup mount for tracking processes. Add
it as another type of controller, albeit one which we have to
special case in a number of places. In particular we must
never create/delete directories there, nor add tasks. Essentially
the systemd mount is to be considered read-only for libvirt.
With this change both the virCgroupDetectPlacement and
virCgroupCopyPlacement methods must be invoked. The copy
placement method will copy setup for resource controllers
only. The detect placement method will probe for any
named controllers, or resource controllers not already
setup.

There are some interesting escaping rules to consider when dealing
with systemd slice/scope names. Thus it is helpful to have APIs

Use the JSON error messages to report errors back to the caller in
addition to erroring out. The error reported from the event loop from
the mock function of the monitor was later overwritten by the call to
the monitor/agent interaction API. This will also allow testing of error
reporting.
The normal monitor uses windows line endings, where the agent monitor
uses only newlines. Change this to tolerate both approaches and allow to
use the utilities for guest agent tests.
Refactor the test helpers to allow adding callbacks to verify the
monitor responses instead of simple command name checking and clean up
various parts to prepare for adding guest agent tests.
The instrumentation for the monitor test can be hacked for qemu agent
testing. Split out the monitor specific stuff to allow using the code in
guest agent tests in the future.
The qemumonitorjsontest crashed when one of the initialization steps
done before starting the worker thread failed. This patch fixes this by
trying to pthread_join() the thread only after it was created.
Although this isn't apparently needed for the guest agent itself, the
test I will be adding later depends on the newline as a separator of
messages to process.
this patch introduce the console api in libxl driver for both pv and
hvm guest. and import and update the libxlMakeChrdevStr function
which was deleted in commit dfa1e1dd.

As RHEL provides a stable tool chain, we don't have to worry about
frequent changes in reported compiler warnings (which prevents us from
enabling -Werror unconditionally).

Libssh2 isn't reliable enough to support the libvirt transport using it.
The problems include mishandling of "known_hosts" files that may confuse
users.
If libapparmor-devel happens to be installed when building the
RPM, it will failed due to unlisted virt-aa-helper in %files.
Add support for apparmor in the spec, so that we can explicitly
turn it on/off, defaulting to off in all distros. This causes
--without-apparmor to be given to configure, preventing the
build failures if the user happens to have libapparmor-devel
present.

The python/tests directory contains a number of so called
"tests" for the python API. These are all hardcoded to
look for Xen and cannot be run in any automated fashion,
and no one is ever manually running them. Given that they
don't meaningully contribute to the test coverage, delete
them.
For some reason these tests were also copied into the
filesystem as part of 'make install'. The change to the
RPM in commit 3347a42032
caused a build failure, since it removed the code which
deleted these installed tests.
