This patch updates functions in netdev.c to pay attention to
phys_port_id. It uses the new function virNetDevGetPhysPortID() to
learn the phys_port_id of a VF or PF, then sends that info to
virPCIGetNetName(), which has newly been modified to take an optional
phys_port_id.
A single PCI device may have multiple netdevs associated with it. Each
of those netdevs will have a different phys_port_id entry in
sysfs. This patch modifies virPCIGetNetName() to allow selecting one
of the potential many netdevs in two different ways:
1) by setting the "idx" argument, the caller can select the 1st (0),
2nd (1), etc. netdev from the PCI device's net subdirectory.
2) If the physPortID arg is set (to a null-terminated string) then
virPCIGetNetName() returns the netdev that has that phys_port_id in
the sysfs file of the same name in the netdev's directory.
On Linux each network device *can* (but not necessarily *does*) have
an attribute called phys_port_id which can be read from the file of
that name in the netdev's sysfs directory. The examples I've seen have
been a many-digit hexadecimal number (as an ASCII string).
This value can be useful when a single PCI device is associated with
multiple netdevs (e.g a dual port Mellanox SR-IOV NIC - this card has
a single PCI Physical Function (PF), and that PF has two netdevs
associated with it (the "net" subdirectory of the PF in sysfs has two
links rather than the usual single link to a netdev directory). Each
of the PF netdevs has a different phys_port_id. The Virtual Functions
(VF) are similar - the PF (a PCI device) has "n" VFs (also each of
these is a PCI device), each VF has two netdevs, and each of the VF
netdevs points back to the VF PCI device (with the "device" entry in
its sysfs directory) as well as having a phys_port_id matching the PF
netdev it is associated with.
virNetDevGetPhysPortID() simply attempts to read the phys_port_id for
the given netdev and return it to the caller. If this particular
netdev driver doesn't support phys_port_id, it returns NULL (*not* a
NULL-terminated string, but a NULL pointer) but still counts it as a
success.
When building libvirt with clang we get bogus warnings about

This code is so complicated because we allow enabling the same
bits at many places. Just like in this case: huge pages can be
enabled by global <hugepages/> element under <memoryBacking> or
on per <memory/> basis. To complicate things a bit more, users
are allowed to omit the page size which case the default page
size is used. And this is what is causing this bug. If no page
size is specified, @pagesize is keeping value of zero throughout
whole function. Therefore we need yet another boolean to hold
[use, don't use] information as we can't sue @pagesize for that.

So the hostdev manager has some lists to keep track which devices
are active (=assigned to a domain) or inactive. The manager and
its lists are allocated in myInit and freed in myCleanup but one
of them (activeSCSIHostdevs) was missing. Also, the order in
which the cleanup was done doesn't make it easy to spot it,
therefore reoder it.

Currently, there's a bug when undefining a domain with NVRAM
store. Basically, the unlink() of the NVRAM store file happens
during the undefine procedure iff domain is inactive. So, if
domain is running and undefine is called the file is left behind.
It won't be removed in the domain cleanup process either
(qemuProcessStop). One of the solutions is to remove if
regardless of the domain state and rely on qemu having the file
opened. This still has a downside that if the domain is defined
back the NVRAM store file is going to be new, any changes to the
current one are lost (just like with any other file that is
deleted while a process has it opened). But is it really a
downside?

Slight refactor of the WMI serialization code to minimize mixing
openwsman and libxml2 APIs that triggered clang alignment warnings.
The only usage of libxml2 APIs now is in creating CDATA blocks,
because the openwsman API does not provide that functionality. The
clang alignment warning in this case is silenced by casting to a
void pointer first.
Validate that we can pass QEMU command line options using a default

The API docs for the various vir$OBJECTGetConnect functions
contain a warning
WARNING: When writing libvirt bindings in other languages, do
not use this function. Instead, store the connection and
the domain object together.
There is no reason why language bindings should not use this
method, and indeed the Perl, Python, and Go bindings all use
these methods.
This warning was originally added back in
commit 3edb4bc9fb

* libvirt.spec.in NEWS docs/* po/*: preparing release 0.3.1
* src/libvirt.c python/generator.py: some cleanup and warnings
from Richard W.M. Jones
IIUC, the rational was that these APIs do not need to be
directly exposed to the non-C language, as the language
can expose the same concept itself by storing the original
virConnectPtr object alongside the virDomainPtr. There's
no reason to mandate such an approach though - it is valid
for languages to expose this directly if that suits their
needs better.

The libxl library allows a libxl_domain_config object to be serialized
from/to a JSON string. Use this to allow testing of the XML to
libxl_domain_config conversion process. Test XML is converted to
libxl_domain_config, which is then serialized to json. A json template
corresponding to the test XML is converted to a libxl_domain_config
object using libxl_domain_config_from_json(), and then serialized
back to json using libxl_domain_config_to_json(). The two json
docs are then compared.
Using libxl to convert the json template to a libxl_domain_config
object and then back to json provides a simple way to account for
any changes or additions to the json representation across Xen
releases.

Certain XML features that aren't in the <cpu> block map to -cpu
flags on the qemu cli. If one of these is specified but the user
didn't explicitly pass an XML <cpu> model, we need to format a
default model on the command line.
The current code handles this by sprinkling this default cpu handling
among all the different flag string formatting. Instead, switch it
to do this just once.
This alters some test output slightly: the previous code would
write the default -cpu in some cases when no flags were actually
added, so the output was redundant.

It turns out that our implementation of the hashing function is
endian-dependent and thus if used on various architectures the testsuite
may have different results. Work this around by mocking virHashCodeGen
to something which does not use bit operations instead of just setting a
deterministic seed.
Disk serial schema has extra '.+' allowed characters in comparison
with check in code. Looks like there is no reason for that as qemu
allows any character AFAIK for serial. This discrepancy is originated
in commit id '85d15b51' where the ability to add serial was added.
Alter the disk-serial test to add a disk with all the possible
characters listed as the serial value.
