This migration cookie is meant for two purposes. The first is to be sent
in begin phase from source to destination to let it know we support new
implementation of VIR_MIGRATE_NON_SHARED_{DISK,INC} so destination can
start NBD server. Then, the second purpose is, destination can let us
know, on which port the NBD server is running.

This just keeps track whether qemu knows nbd-server-* commands
so we can use it during migration or not.

This patch adds support for a new <option>-Tag in the <dhcp> block of
network configs, based on a subset of the fifth proposal by Laine
Stump in the mailing list discussion at
https://www.redhat.com/archives/libvir-list/2012-November/msg01054.html.
Any such defined option will result in a dhcp-option=<number>,"<value>"
statement in the generated dnsmasq configuration file.

Currently, DHCP options can be specified by number only and there is
no whitelisting or blacklisting of option numbers, which should
probably be added.

Nothing in run required bash, except for the shebang.  On systems
where /bin/bash doesn't exist (I hit it on FreeBSD), using /bin/sh
instead fixes a 'make check' failure:
gmake[3]: Entering directory `/usr/home/dummy/libvirt/python'
  GEN    check-local
/usr/local/bin/bash: ../run: /bin/bash: bad interpreter: No such file or directory

* run.in: Use /bin/sh, not bash.

The bfree and blocks fields are supposed to be in units of frsize.  We were
calculating capacity correctly using those units, but the available
calculation was using bsize instead.  Most file systems report these as the
same value specifically because many programs are buggy, but that is no
reason to rely on that behavior, or to behave inconsistently.

This bug has been present since e266ded2 (2008) and aa296e6c, when the code
was originally introduced (the latter via cut and paste).

On FreeBSD, I got a 'make check' failure:
  GEN    check-symsorting
Symbol block at ./libvirt_atomic.syms:4: viratomic.h not found

* src/Makefile.am (SYM_FILES): New define.
(check-symsorting): Check on all symfiles, even when not used.

This is a command wrapping virDomainMigrateGetCompressionCache and
virDomainMigrateSetCompressionCache.

Introduce virDomainMigrateGetCompressionCache and
virDomainMigrateSetCompressionCache APIs.

As a side effect, this also fixes reporting disk migration process.
It was added to memory migration progress, which was wrong. Disk
progress has dedicated fields in virDomainJobInfo structure.

remoteDeserializeTypedParameters can now be called with either
preallocated params array (size of which is announced by nparams) or it
can allocate params array according to the number of parameters received
from the server.

This is an extensible version of virDomainGetJobInfo.

This flag may be used with migration APIs to request compression of
migration data.

Fix the caps-qemu-kvm.xml test data file to refer to correct
arm arch name.

When the virarch.c file was introduced to formalize the arch
list, we forgot to update the RNG schema with the new arches.

It's only freed on normal returns from virDomainVideoDefParseXML,
but not when erroring out.

Patch has been accepted into net-next's 3.9 queue to correctly expose
bond interfaces with the 'bond' devtype.

The udev backend now supports bond interfaces.

Refactored the interface device type identification to make it more
clear about the operations. Add support for udev devtype to detect
VLANs on Linux 3.7 and newer. Move VLAN detection based on device
name to fallback case.

Mechanical move to break up udevIfaceGetIfaceDef() into different
helpers for each of the interface types to hopefully make the code
easier to follow. This moves the vlan code to
udevIfaceGetIfaceDefVlan().

Based on feedback from Laine Stump, improve a number of the error
handling cases to report the issue to the user instead of not generating
data or giving vague errors. Added the bridge device name to every error
message as well to make it clear which bridge failed.

https://bugzilla.redhat.com/show_bug.cgi?id=896685 points out
a regression caused by commit 38c4a9cc - libvirt only labels
the backing chain if the backing chain cache is populated, but
the code to populate the cache was only conditionally performed
if cgroup labeling was necessary.

* src/qemu/qemu_cgroup.c (qemuSetupCgroup): Hoist cache setup...
* src/qemu/qemu_process.c (qemuProcessStart): ...earlier into
caller, where it is now unconditional.

Get rid of the "identical" variable in the ABI stability checks in favor
of return statements and break or refactor very long lines where
possible.

Declare local variables at the start of the block and fix trivial
formatting issues.

Many of the headers were using the old style and even overflowing the 80
column mark.

The label named "cleanup" was used in error cases only. Change it to
"error".

Use the correct type and get rid of "default" label in switch to make
the compiler complain if a new device type is added.

Change the error label to "error" and simplify some error paths.
