Similar in theory to *AssignDef type functions, this duplicate functionality
will be used by an future FindPoolSources implementations.

We need to parse a source XML block for FindPoolSources, so this is a step
in sharing the parsing. The new storage pool XML 2 XML tests cover this area
pretty well to ensure we aren't causing regressions.

This patch adds an optional attribute to the <bootp> tag, that
allows to specify a TFTP server address other than the address of
the DHCP server itself.

This can be used to forward the BOOTP settings of the host down to the
guest.  This is something that configurations such as Xen's default
network achieve naturally, but must be done manually for NAT.

* docs/formatnetwork.html.in: Document new attribute.
* docs/schemas/network.rng: Add it to schema.
* src/conf/network_conf.h: Add it to struct.
* src/conf/network_conf.c: Add it to parser and pretty printer.
* src/network/bridge_driver.c: Put it in the dnsmasq command line.
* tests/networkxml2xmlin/netboot-proxy-network.xml
  tests/networkxml2xmlout/netboot-proxy-network.xml
  tests/networkxml2xmltest.c: add new tests

In xenInotifyXendDomainsDirLookup() the wrong UUID variable is used
to search in the config info list.

In xenInotifyEvent() the event is dispatched if it's NULL.

Both were introduced in bc898df2.

* src/qemu/qemu_conf.c: change the error message to refer to
  'cgroup_controllers' instead of 'cgroup_device_acl'

We should always be using virGetHostname in place of
gethostname; thus add in a new syntax-check rule to make
sure no new uses creep in.

Make a pass over the syntax-check files, tightening up regex's,
un-ignoring certain files, and cleaning things up.
Signed-off-by: NChris Lalancette <clalance@redhat.com>

We can slightly tighten up the regex's used to detect the use of
nonreentrant functions.  We can also check src/util/virterror.c
by modifying a comment; I think it's worth it to get the additional
coverage.

xenUnifiedDomainEventRegister() calls out to
virDomainEventCallbackListAdd(), which increments the reference
count on the connection.  That is fine, but then
xenUnifiedDomainEventRegister() increments the usage count again,
leading to a usage count leak.  Remove the increment in the xen
register, and the UnrefConnect in the xen unregister.

If no matching device was found (cap == NULL) then no strdup() call
was made and *wwnn and *wwpn are untouched. Checking them for NULL
in this situation may result in reporting an false-positive OOM error
because *wwnn and *wwpn may be initialized to NULL by the caller.

Only check *wwnn and *wwpn for NULL if a matching device was found
(cap != NULL) and thus strdup() was called.

* src/conf/node_device_conf.c: only report an OOM error if there
  really is one

virXPathNodeSet() could return -1 when doing an evaluation failure
due to xmlXPathEval() from libxml2 behaviour.
* src/util/xml.c: make sure we always return 0 unless the returned
  XPath type is of the wrong type (meaning the query passed didn't
  evaluate to a node set and code must be fixed)

This adds simple support for configuring a guest with a QEMU/KVM
virtual hardware watchdog device.

Without this, after few weeks without use, each defined domain grows a
tail of empty gzipped logs, instead of keeping just the last log of
interest.

* daemon/libvirtd.logrotate.in: only rotate when the log is over 100 KBytes

virsh -c lxc:/// autostart vm1
was crashing the daemon

* src/lxc/lxc_conf.h src/lxc/lxc_conf.c: initialize the driver
  autostartDir to avoid a NULL reference and implement autostart for LXC

* tools/virsh.c: call to vshError() containing 'doexit' parameter
  sneaked in after said parameter was removed

* src/Makefile.am: add selinux CFLAGS and linker flags to security driver

Currently MAC address configuration of container veth is just ignored.
This patch implements the missing feature.

* src/lxc/veth.c, src/lxc/veth.h: add setMacAddr
* src/lxc/lxc_driver.c: set macaddr of container veth if specified

* tests/Makefile.am: networkpoolxml2xmlout and networkpoolxml2xmlin are
  really networkxml2xmlout and networkxml2xmlin

These will be used by the test driver, so move them to a shareable space.

Certain error paths won't unlock the node device object.

Provide a simple interface for other tests to lookup the testDebug variable.
Also remove a redundant error message in interface tests.

If anyone feels inclined to change this env variable to match the existing
LIBVIRT_* format, it should now be easier to do so.

Otherwise any virRandom calls will result in a segfault.

Most of the hash iterators need to modify either payload of
data args. The const annotation prevents this.

* src/util/hash.h, src/util/hash.c: Remove const-ness from
  virHashForEach/Iterator
* src/xen/xm_internal.c: Remove bogus casts

* src/libvirt.c: remove reverences to non existent dconn parameter
  when using that entry point.

A cgroup file returns integer value terminated with '\n' and remaining
it has sometimes harmful effects, for example it leads virStrToLong_ull
to fail.
* src/util/cgroup.c: strip out terminating \n when reading a value

Introduced in commit 39a7be47.

* tests/*schematest: replace 'source' with '.'
* tests/schematestutils.sh: remove 'function' keyword and add '()'

Make things a bit more readable, and properly handle forward mode 'route'.

Move existing schema data to an input directory. Add extra files for more
thorough XML testing.

All schema tests have identical functionality, so avoid the duplication.
