We were requiring a USB port path in the schema, but not enforcing it.
Omitting the USB port would lead to libvirt formatting it as (null).
Such domain cannot be started and will disappear after libvirtd restart
(since it cannot parse back the XML).
Only format the port if it has been specified and mark it as optional
in the XML schema.
Commit id's '9bbf0d7e6' and '2552fec24' added some XML parsing tests
for a LUKS volume to use a 'passphrase' secret format. After commit,
this was deemed to be incorrect, so covert the various tests to use
the volume usage format where the 'usage' is the path to the volume
rather than a user defined name string.
Also, removed the qemuxml2argv-luks-disk-cipher.xml since it was
just a duplicate of qemuxml2argv-luks-disks.xml.

Commit ca10bb040f introduced a new test that fails to build
on at least some architectures:
commandtest.c: In function 'test25':
commandtest.c:1121:5: error: comparison is always true due to
limited range of data type [-Werror=type-limits]
if (rv >= 0) {
^
Change the type of 'rv' from char to int, which is the proper
return type for virCommandExec() anyway.
We can't mock tests on Mingw, which lacks dlopen() and friends;
follow the paradigms used in other mock files of conditionally
compiling nothing when not building for Linux.

Commit c9c03ea stopped creating an intermediate file during syntax-check
to save on execution time. It also switched to outputting the whole
incorrectly wrapped file instead of a diff needed to fix it.
Feed the newly wrapped file to diff via a pipe.
Note that fixing it by running test-wrap-argv.pl --in-place or
the unit test with VIR_TEST_REGENERATE_OUTPUT is easier.
Commit 843a70a changed test-wrap-argv.pl to use
/usr/bin/env perl
instead of
/usr/bin/perl
However when called from qemuxml2argvtest with
VIR_TEST_REGENERATE_OUTPUT, PATH is set to '/bin'.
Find the path to perl early in virTestMain, in case we
are going to need it later after we've overridden PATH.

The virconftest is different from all our other tests in that
the C program only tests a single in/out config file pair. It
relies on a shell wrapper to invoke it once for each test
file.
This gets rid of the shell wrapper and makes the C program
actually run over each test file using the normal test pattern.

In the mock, we have a stub for virNetDevTapCreate(). However,
the mocked version does not exactly as it's native counterpart.
The function receives a string, which is an interface name that
caller would like to have, but it's not guaranteed that they will
get just that one. If they don't, the function free()-s the one
passed and returns the new one. Just like the mocked version. But
what is the mocked version missing is the free().

Status XML tests were done by prepending a constant string to an
existing XML. With the planned changes the header will depend on data
present in the definition rather than just on the data that was parsed.
The first dynamic element in the header will be the vcpu thread list.
Reuse and rename qemuXML2XMLPreFormatCallback for gathering the relevant
data when checking the active XML parsing and formating and pass the
bitmap to a newly crated header generator.
As the empty bitmap exists, we should also test it. This patch adds
test cases for the procedures 'virBitmapNextSetBit', 'virBitmapLastSetBit',
'virBitmapNextClearBit'.

For type='ethernet' interfaces only.
(This patch had been pushed earlier in
commit 0b4645a7e0, but was reverted in
commit 84d47a3cce because it had been
accidentally pushed during the freeze for release 2.0.0)
This is place as a sub-element of <source>, where other aspects of the
host-side connection to the network device are located (network or
bridge name, udp listen port, etc). It's a bit odd that the interface
we're configuring with this info is itself named in <target dev='x'/>,
but that ship sailed long ago:
<interface type='ethernet'>
<mac address='00:16:3e:0f:ef:8a'/>
<source>
<ip address='192.168.122.12' family='ipv4'
prefix='24' peer='192.168.122.1'/>
<ip address='192.168.122.13' family='ipv4' prefix='24'/>

<route family='ipv4' address='192.168.124.0' prefix='24'
gateway='192.168.124.1'/>
</source>
</interface>
In practice, this will likely only be useful for type='ethernet', so
its presence in any other type of interface is currently forbidden in
the generic device Validate function (but it's been put into the
general population of virDomainNetDef rather than the
ethernet-specific union member so that 1) we can more easily add the
capability to other types if needed, and 2) we can retain the info
when set to an invalid interface type all the way through to
validation and report a proper error, rather than just ignoring it
(which is currently what happens for many other type-specific
settings).
(NB: The already-existing configuration of IP info for the guest-side
of interfaces is in subelements directly under <interface>, and the
name of the guest-side interface (when configurable) is in <guest
dev='x'/>).

In order to use more common code and set up for a future type, modify the
encryption secret to allow the "usage" attribute or the "uuid" attribute
to define the secret. The "usage" in the case of a volume secret would be
the path to the volume as dictated by the backwards compatibility brought
on by virStorageGenerateQcowEncryption where it set up the usage field as
the vol->target.path and didn't allow someone to provide it. This carries
into virSecretObjListFindByUsageLocked which takes the secret usage attribute
value from from the domain disk definition and compares it against the
usage type from the secret definition. Since none of the code dealing
with qcow/qcow2 encryption secrets uses usage for lookup, it's a mostly
cosmetic change. The real usage comes in a future path where the encryption
is expanded to be a luks volume and the secret will allow definition of
the usage field.
This code will make use of the virSecretLookup{Parse|Format}Secret common code.

When support for <interface type='ethernet'> was added in commit
9a4b705f back in 2010, it erroneously looked at <source dev='blah'/>
for a user-specified guest-side interface name. This was never
documented though. (that attribute already existed at the time in the
data.ethernet union member of virDomainNetDef, but apparently had no
practical use - it was only used as a storage place for a NetDef's
bridge name during qemuDomainXMLToNative(), but even then that was
never used for anything).
When support for similar guest-side device naming was added to the lxc
driver several years later, it was put in a new subelement <guest
dev='blah'/>.
In the intervening years, since there was no validation that
ethernet.dev was NULL in the other drivers that didn't actually use
it, innocent souls who were adding other features assuming they needed
to account for non-NULL ethernet.dev when really they didn't, so
little bits of the usual pointless cargo-cult code showed up.
This patch not only switches the openvz driver to use the documented
<guest dev='blah'/> notation for naming the guest-side device (just in
case anyone is still using the openvz driver), and logs an error if
anyone tries to set <source dev='blah'/> for a type='ethernet'
interface, it also removes the cargo-cult uses of ethernet.dev and
<source dev='blah'/>, and eliminates if from the RNG and from
virDomainNetDef.
NB: I decided on this course of action after mentioning the
inconsistency here:
https://www.redhat.com/archives/libvir-list/2016-May/msg02038.html
and getting encouragement do eliminate it in a later IRC discussion
with danpb.
