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

https://bugzilla.redhat.com/show_bug.cgi?id=528575
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.

If the the qemu and kvm binaries are the same, we don't include machine
types in the kvm domain info.

However, the code which refreshes the machine types info from the
previous capabilities structure first looks at the kvm domain's info,
finds it matches and then copies the empty machine types list over
for the top-level qemu domain.

That doesn't make sense, we shouldn't copy an empty machin types list.

* src/qemu/qemu_conf.c: qemudGetOldMachinesFromInfo(): don't copy an
  empty machine types list.

* src/util/buf.c: if virBufferEscapeString was called on a buffer that
  had 0 bytes of space, a size of -1 will be passed to snprintf, resulting
  in a segmentation fault, this preallocate some space.

* src/conf/storage_conf.c src/conf/storage_conf.h: extend the enums
  and values
* docs/schemas/storagepool.rng: add to the list of storage pool type
  formats

* src/lxc/lxc_driver.c: without PATH, the controller will definitely
  fail to call ip command

Normally, when you migrate a domain from host A to host B,
the domain on host A remains defined but shutoff and the domain
on host B remains running but is a "transient".  Add a new
flag to virDomainMigrate() to allow the original domain to be
undefined on source host A, and a new flag to virDomainMigrate() to
allow the new domain to be persisted on the destination host B.

When specifying bridge delay via network XML define, we were looking for
the 'delay' attribute, but would dump the value as 'forwardDelay'. Have
the output match the expected input (and schema).

The fread_file_lim() function uses fread() but never handles
EINTR results, causing unexpected failures when reading QEMU
help arg info. It was unneccessarily using FILE * instead
of plain UNIX file handles, which prevented use of saferead()

* src/util/util.c: Switch fread_file_lim over to use saferead
  instead of fread, remove FILE * use, and rename

We were missing a closing tag, so the XML wasn't proper.

- mpath pools weren't listed
- scsi pools were missing an adapter section
- iscsi pools were missing an auth section
- Logical pools do not require a source name to be specified

$ sudo virsh pool-start idontexist
10:58:18.716: warning : processCallDispatchReply:7612 : Method call error
error: failed to get pool 'idontexist'
error: Storage pool not found: no pool with matching name 'idontexist'

That warning doesn't server much purpose being printed via a virsh call. So
remove the message.

This matches the behavior of domains, storage, etc. Also, fix up some
whitespace issues in the area.

The logic for running the decompression programs was broken in
commit f2387093, so that for
non-raw formats the decompression program was never run, and
for raw formats, it tried to exec an argv[] with initial NULL
in the program name.

* src/qemu/qemu_driver.c: Fix logic in runing decompression program

In lxcVmStart we first should not reuse rc for another purpose
than the return value.

* src/lxc/lxc_driver.c: don't reuse rc for local procedure calls

* docs/Makefile.am: the lack of a target for devhelp/libvirt.devhelp
  broke 'make dist'

* libvirt.spec.in: missing % broke 'make rpm'
