So far, CPUID data were stored in two different data structures. First
of them was a structure allowing direct access for CPUID data according
to function number and the second was a plain array of struct
cpuX86cpuid. This was a silly design which resulted in converting data
from one type to the other and back again or implementing similar
functionality for both data structures.

The patch leaves only the direct access structure. This makes the code
both smaller and more maintainable since operations on different objects
can use common low-level operations.

All 57 tests for cpu subsystem still pass after this rewrite.

Remove superfluous ": %s" suffix from the error message.

We were doing so for child processes but not for libvirtd itself.

Without this fix, ./configure --with-libpcap will cause --with-libpcap=yes
to be implicitly passed down, which cause yes/bin/pcap-config to be
searched for rather than /usr/bin/pcap-config.

Also output pcap: no when pcap is not found or disabled.

Currently, all of domain "save/dump/managed save/migration"
use the same function "qemudDomainWaitForMigrationComplete"
to wait the job finished, but the error messages are all
about "migration", e.g. when a domain saving job is canceled
by user, "migration was cancled by client" will be throwed as
an error message, which will be confused for user.

As a solution, intoduce two new job types(QEMU_JOB_SAVE,
QEMU_JOB_DUMP), and set "priv->jobActive" to "QEMU_JOB_SAVE"
before saving, to "QEMU_JOB_DUMP" before dumping, so that we
could get the real job type in
"qemudDomainWaitForMigrationComplete", and give more clear
message further.

And as It's not important to figure out what's the exact job
is in the DEBUG and WARN log, also we don't need translated
string in logs, simply repace "migration" with "job" in some
statements.

* src/qemu/qemu_driver.c

The "Default-Stop" field in LSB comment in libvirt-guests is missing and should
be added. I also suggests to add runlevel 2 to the "Default-Start" field.

Current code does not pass VM mac address to a 802.1Qbh direct attach
interface using IFLA_VF_MAC.  This patch adds support in macvtap code to
send IFLA_VF_MAC netlink request during port profile association on a
802.1Qbh interface.

Stefan Cc'ed for comments because this patch changes a condition for
802.1Qbg

802.1Qbh support for IFLA_VF_MAC in enic driver has been posted and is
pending acceptance at http://marc.info/?l=linux-netdev&m=129185244410557&w=2

* src/libvirt_private.syms (command.h): Export them.
* src/qemu/qemu_conf.c (qemudBuildCommandLine): Use them, plugging
a memory leak on rbd_hosts in the process.

* src/conf/domain_conf.c (virDomainGraphicsDefParseXML)
(virDomainDeviceVirtioSerialAddressParseXML)
(virDomainDiskDefFree): Free various leaks.

* tests/qemuxml2argvtest.c (testCompareXMLToArgvFiles): Don't
allocate, since we don't use virDomainChrDefFree.

* src/util/util.c (__virExec): Don't use FD_ISSET on out-of-bounds fd.

This is pretty straightforward - even though dnsmasq gets daemonized
and uses a pid file, those things are both handled by the dnsmasq
binary itself. And libvirt doesn't need any of the output of the
dnsmasq command either, so we just setup the args and call
virRun(). Mainly it was just a (mostly) mechanical job of replacing
the APPEND_ARG() macro (and some other *printfs()) with
virCommandAddArg*().
