This travis configuration tests libvirt builds on 5 platforms that we don't
exercise in the CentOS CI system.

  - Ubuntu Trusty with GCC
  - Ubuntu Trusty with CLang
  - Ubuntu Precise with GCC
  - Ubuntu Precise with CLang
  - OS-X with CLang

NB, syntax-check fails on OS-X with errors like:

   /bin/sh: /usr/bin/grep: Argument list too long

Presumably their grep impl isn't as good as the GNU one, so this test
config skips syntax-check on OS-X for now.

CLang's optimizer is more aggressive at inlining functions than
gcc and so will often inline functions that our tests want to
mock-override. This causes the test to fail in bizarre ways.

We don't want to disable inlining completely, but we must at
least prevent inlining of mocked functions. Fortunately there
is a 'noinline' attribute that lets us control this per function.

A syntax check rule is added that parses tests/*mock.c to extract
the list of functions that are mocked (restricted to names starting
with 'vir' prefix). It then checks that src/*.h header file to
ensure it has a 'ATTRIBUTE_NOINLINE' annotation. This should prevent
use from bit-rotting in future.

/etc/libvirt/nwfilter/*.xml files are installed with no UUID, which
means libvirtd will automatically alter all of them once it starts. Thus
RPM verification will always fail on them. Let's use a trick similar to
the default network XML and store nwfilter XMLs in /usr/share. They will
be copied into /etc in %post. Additionally the /etc files are marked as
%ghost so that they are uninstalled if the RPM package is removed.

Note that the %post script overwrites existing files with new ones on
upgrade, which is what has always been happening.

Use "virNetworkObj" as a prefix for any external API in virnetworkobj.

Also a couple of functions were local to virnetworkobj.c, so remove their
external defs in virnetworkobj.h.

Rename the API to be a better description of what it does. Besides, a
subsequent patch will rename virNetworkAssignDef to virNetworkObjAssignDef
so rather than make that patch confusing we'll take the intermittent step
in this patch.

In an effort to be consistent with the source module, alter the function
prototypes to follow the similar style of source with the "type" on one
line followed by the function name and arguments on subsequent lines with
with argument getting it's own line.

Alter the format of the code to follow more recent style guidelines of
two empty lines between functions, function decls with "[static] type"
on one line followed by function name with arguments to functions each
on one line.

Move all the virNetworkObj related API/data structures into their own
modules virnetworkobj.{c,h} from the network_conf.{c,h}

Purely code motion at this point plus adjustments to cleanly build

When hyperv code generator for WMI classes identifies common
properties, it needs to take into account array type as a distinct
type, i.e string != string[]. This is the case where v1 of the
Msvm_VirtualSystemSettingData has Notes property as string whereas v2
uses Notes[], therefore they have to be treated as different fields and
cannot be placed in the "common" struct.

Since the disks are copied by qemu, there's no need to enforce
cache=none. Thankfully the code that added qemuMigrateDisk did not break
existing configs, since if you don't select any disk to migrate
explicitly the code behaves sanely.

The logic for determining whether a disk should be migrated is
open-coded since using qemuMigrateDisk twice would be semantically
incorrect.

If the parent is not a scsi_host, then we can just happily return since
we won't be removing a vport.

Fixes a bug with the following output:

The virStoragePoolObjSourceFindDuplicate logic used by PoolCreateXML
and PoolDefineXML avoids comparing the new definition against "other"
pool types. This can cause unexpected corruption if two different pool
source types used the same source device path. For example, a 'disk'
pool using source type device=/dev/sdc could be unwittingly overwritten
by using /dev/sdc for a 'logical' pool which also uses the source
device path.

So rather than blindly ignoring those checks when def->type !=
pool->def->type - have the pool->def->type switch logic handle the
check for which def->type's should be checked.

Refactor virStoragePoolObjSourceFindDuplicate into smaller units
separated by the "supported" pool source type. The ISCSI, FS,
LOGICAL, DISK, and ZFS pools can use "<source>... <device='%s'/>...
</source>".

Alter the logic slightly to return the matching pool or NULL rather
than setting matchpool = pool and break.  Easier to read that way.

In the effort to reduce the virStoragePoolObjSourceFindDuplicate logic,
create a new helper which will handle all the ISCSI type differences.

Alter things just a little bit to return NULL or pool rather than
using breaks and matchpool = pool, then break. Also rather than creating
variables withing the if...else if... conditions, have them all at the
top of the function to make things a bit easier to read.

Refactor virStoragePoolObjSourceFindDuplicate into smaller units
separated by the "supported" pool source type. The DIR, GLUSTER,
and NETFS pools all can use "<source>... <dir='%s'/>... </source>".

Alter the logic slightly to return the matching pool or NULL rather
than setting matchpool = pool and break.  Easier to read that way.

Introduce a separate buffer for options and use a helper
variable for def->iommu.

Do not probe for devices that QEMU does not know
when probing for device options.
