We need to start NBD server and feed it with all non-<shared/>,
RW and source-full disks. Moreover, with new virPortAllocator we
must ensure the borrowed port for NBD server will be returned if
either migration completes or qemu process is torn down.
This will be used with new migration scheme.
This patch creates basically just monitor stub
functions. Wiring them into something useful
is done in later patches.

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 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 e266ded (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.
* src/libvirt_atomic.syms: Fix offender.
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.
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 38c4a9c - 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.
To avoid having to hold the qemu driver lock while iterating through
close callbacks and calling them. This fixes a real deadlock when a
domain which is being migrated from another host gets autodestoyed as a
result of broken connection to the other host.
The max value of number of cpus to compute(id) should not
be equal or greater than max cpu number.
The bug ocurrs when id value is equal to max cpu number which
leads to the off-by-one error in the following for loop.
# virsh cpu-stats guest --start 1
error: Failed to virDomainGetCPUStats()
error: internal error cpuacct parse error
Don't allow interval to be > MAX_INT/1000 in virKeepAliveStart()
Guard against possible overflow in virKeepAliveTimeout() by setting the
timeout to be MAX_INT/1000 since the math following will multiply it by 1000.
