Move all the code that manages stop/start of LXC processes
into separate lxc_process.{c,h} file to make the lxc_driver.c
file smaller

Move the cgroup setup code out of the lxc_controller.c file
and into lxc_cgroup.{c,h}. This reduces the size of the
lxc_controller.c file and paves the way to invoke cgroup
setup from lxc_driver.c instead of lxc_controller.c in the
future

Make sure that libvirt_private.syms has all the internal symbols
from APIs in src/rpc/*.h and src/util/cgroup.h, since the LXC

In the delayed close mode, we're just waiting for final data to
be written back to the client. While waiting, we should not
bother to read more data from the client.

When sending SIGHUP to libvirtd, it will trigger the virStateDriver
reload operation. This is intended to reload the configuration files
for guests. For unknown historical reasons this is also triggering
autostart of all guests. Autostart is generally expected to be
something that happens on OS startup. Starting VMs on SIGHUP will
violate that expectation and potentially cause dangerous scenarios
if the admin has explicitly shutdown a misbehaving VM that has
been marked as autostart

Turning on the building of driver modules in libvirt.spec.in
means that installing 'libvirt' no longer pulls in all the
drivers. For upgrade compatibility we need to list all drivers
module sub-RPMs against the 'libvirt' RPM.

Update the linux bridge driver to use virReportError instead

Instead of only removing the ending newline character, it is
better to remove all of standard whitespace character for the
sake of log format.
One example that we have to do this is:
After three times incorrect password input, virsh command
virsh -c qemu://remoteserver/system will report error like:
: Connection reset by peerey,gssapi-keyex,gssapi-with-mic,password).
But it should be:
Permission denied (publickey,gssapi-keyex,gssapi-with-mic,password).
: Connection reset by peer
The reason is that we dropped the newline, but have a '\r' left.
The terminal interprets it as "move the cursor back to the start
of the current line", so the error string is messed up.
It was broken since forever as it expected a libxml2
XML_ELEMENT_NODE containing a XML_TEXT_NODE instead of
just a XML_TEXT_NODE.
This problem was not discovered for so long because
esxVI_String_Deserialize was not used until now.

Commit 80533ca forgot to think about offline cpus. When a node
cpu is offline, then its topology/ subdirectory is not present,
leading to spurious error messages leaked to the user such as:
libvir: error : cannot open /home/dummy/libvirt/tests/nodeinfodata/linux-nodeinfo-sysfs-test-6/node/node0/cpu7/topology/physical_package_id: No such file or directory
Fix that, as well as test it; the test data is gathered from a
machine with one NUMA node, hyperthreading, and with 2 of the
8 cpus offline.
* src/nodeinfo.c (virNodeParseNode): Don't parse topology of
offline cpus.
* tests/nodeinfotest.c (mymain): Run new test.
* tests/nodeinfodata/linux-nodeinfo-sysfs-test-6*: New data.

This patch brings support to manage sheepdog pools and volumes to libvirt.
It uses the "collie" command-line utility that comes with sheepdog for that.
A sheepdog pool in libvirt maps to a sheepdog cluster.
It needs a host and port to connect to, which in most cases
is just going to be the default of localhost on port 7000.
A sheepdog volume in libvirt maps to a sheepdog vdi.
To create one specify the pool, a name and the capacity.
Volumes can also be resized later.
In the volume XML the vdi name has to be put into the <target><path>.
To use the volume as a disk source for virtual machines specify
the vdi name as "name" attribute of the <source>.
The host and port information from the pool are specified inside the host tag.
<disk type='network'>
...
<source protocol="sheepdog" name="vdi_name">
<host name="localhost" port="7000"/>
</source>
</disk>
To work right this patch parses the output of collie,
so it relies on the raw output option. There recently was a bug which caused
size information to be reported wrong. This is fixed upstream already and
will be in the next release.

Basically within a Secure Linux Container (virt-sandbox) we want all content
that the process within the container can write to be labeled the same. We
are labeling the physical disk correctly but when we create "RAM" based file
systems
libvirt is not labeling them, and they are defaulting to tmpfs_t, which will
will not allow the processes to write. This patch labels the RAM based file
systems correctly.

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

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, ...)

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.
The previous commit (387117ad92) was incomplete leaving those
who does not use libpcap with uncompilable sources beacuse
of incomplete conversion of virNWFilterDHCPSnoopReq function.
Introduce new members in the virMacAddr 'class'
- virMacAddrSet: set virMacAddr from a virMacAddr
- virMacAddrSetRaw: setting virMacAddr from raw 6 byte MAC address buffer
- virMacAddrGetRaw: writing virMacAddr into raw 6 byte MAC address buffer
- virMacAddrCmp: comparing two virMacAddr
- virMacAddrCmpRaw: comparing a virMacAddr with a raw 6 byte MAC address buffer
then replace raw MAC addresses by replacing
- 'unsigned char *' with virMacAddrPtr
- 'unsigned char ... [VIR_MAC_BUFLEN]' with virMacAddr
and introduce usage of above functions where necessary.
