2fc011fe04 tests: qemuargv2xml: Drop memory XML blanking
The memory XML blanking is only there to avoid the unit= churn that
was added by default a long time ago.

Drop the blanking, switch over to using the standard comparison
helpers, and regenerate the output with VIR_TEST_REGENERATE_OUTPUT.

73ed1d7401 tests: qemuargv2xml: hardcode disk auth usage
If a qemuargv has iscsi or ceph secrets on the command line, we will
convert that to XML like:

  <auth username='myname'>
    <secret type='iscsi'/>
  </auth>

This is not valid XML, as either a UUID or usage must be specified in
the secret block. It's not clear though how the argv2xml code can do
anything correct here, since XML like this requires a libvirt secret
object to have already been defined.

The current test suite handles this by blanking out any <secret> block
in the XML. This avoids domainschematest failures.

Instead of blanking, let's hardcode a usage= name. This lets us test
the other bits of generated <secret> XML, and is a step towards wiring
up VIR_TEST_REGENERATE_OUTPUT

d860b2f537 qemu: Split the command parsing routines into own module
Extract out the qemuParseCommandLine{String|Pid} into their own
separate module - taking with it all the various static functions.

Causes a ripple effect with a few other modules to include the
new qemu_parse_command.h.

Narrowed down the list of #include's in the split out module to
those that are necessary for build.

e117bf642b tests: qemuargv2xml: separate from qemuxml2argv data
Most of the qemuargv2xml tests are parsing old style qemu command
lines (with -disk, -serial, etc), and it gets its input from
qemuxml2argv output.

But since we've raise the minimum supported qemu version to 0.12.0,
which supports -device, once that changes propagates through libvirt
the vast majority of qemuxml2argv output is _not_ going to be using
old style qemu options.

In preparation for this, switch qemuargv2xml to use its own copies
of input and output, so it's not tied to qemuxml2argv results.

This is just a straight copy of the current tests.

7712fc7cdb qemuargv2xmltest: Resurrect RBD and iSCSI auth
Ressurect the disk-drive-network-iscsi-auth and disk-drive-network-rbd-auth
tests.  Make adjustments to the args and xml file to be compatible with
other changes made to the non "-auth" so that the only difference is the
authentication information.

Adjust the qemuargv2xmltest.c to filter out "<secret" and "</auth>" since
the args -> xml has no concept of usage it doesn't get printed. This results
in the </auth> being printed on the same line as "<secret" and the secret
XML is not closed - a bit of an issue, but soon to be fixed.

b7b3fb56f5 test: display qemuParseCommandline warnings when VIR_TEST_DEBUG > 0
qmeuargv2xmltest.c would fail any test that logged anything during
qemuParseCommandline(), but then discard the log message, even with
VIR_TEST_DEBUG=2. This patch outputs the log messages with
fprintf(stderr,...) when debug logging is on.

In the process of modifying that logic, the testInfo data was made
more similar to that of qemuxml2argvtest.c - rather than turning
info->extraFlags into a bool, an enum of flags is defined, the info
struct is given an "unsigned int flags", and FLAG_EXPECT_WARNING is
saved into info->flags, to be checked during the test; this will make
it easier to add other FLAG_EXPECT_* items in the future.

590029f672 Introduce new OOM testing support
The previous OOM testing support would re-run the entire "main"
method each iteration, failing a different malloc each time.
When a test suite has 'n' allocations, the number of repeats
requires is  (n * (n + 1) ) / 2.  This gets very large, very
quickly.

This new OOM testing support instead integrates at the
virtTestRun level, so each individual test case gets repeated,
instead of the entire test suite. This means the values of
'n' are orders of magnitude smaller.

The simple usage is

   $ VIR_TEST_OOM=1 ./qemuxml2argvtest
   ...
   29) QEMU XML-2-ARGV clock-utc                                         ... OK
       Test OOM for nalloc=36 .................................... OK
   30) QEMU XML-2-ARGV clock-localtime                                   ... OK
       Test OOM for nalloc=36 .................................... OK
   31) QEMU XML-2-ARGV clock-france                                      ... OK
       Test OOM for nalloc=38 ...................................... OK
   ...

the second lines reports how many mallocs have to be failed, and thus
how many repeats of the test will be run.

If it crashes, then running under valgrind will often show the problem

  $ VIR_TEST_OOM=1 ../run valgrind ./qemuxml2argvtest

When debugging problems it is also helpful to select an individual
test case

  $ VIR_TEST_RANGE=30 VIR_TEST_OOM=1 ../run valgrind ./qemuxml2argvtest

When things get really tricky, it is possible to request that just
specific allocs are failed. eg to fail allocs 5 -> 12, use

  $ VIR_TEST_RANGE=30 VIR_TEST_OOM=1:5-12 ../run valgrind ./qemuxml2argvtest

In the worse case, you might want to know the stack trace of the
alloc which was failed then VIR_TEST_OOM_TRACE can be set. If it
is set to 1 then it will only print if it thinks a mistake happened.
This is often not reliable, so setting it to 2 will make it print
the stack trace for every alloc that is failed.

  $ VIR_TEST_OOM_TRACE=2 VIR_TEST_RANGE=30 VIR_TEST_OOM=1:5-5 ../run valgrind ./qemuxml2argvtest
  30) QEMU XML-2-ARGV clock-localtime                                   ... OK

1a308ee015 qemu: add support for libiscsi
libiscsi provides a userspace iSCSI initiator.

The main advantage over the kernel initiator is that it is very
easy to provide different initiator names for VMs on the same host.
Thus libiscsi supports usage of persistent reservations in the VM,
which otherwise would only be possible with NPIV.

libiscsi uses "iscsi" as the scheme, not "iscsi+tcp".  We can change
this in the tests (while remaining backwards-compatible manner, because
QEMU uses TCP as the default transport for both Gluster and NBD).

27cf98e2d1 virCaps: conf: start splitting out irrelevat data
The virCaps structure gathered a ton of irrelevant data over time that.
The original reason is that it was propagated to the XML parser
functions.

This patch aims to create a new data structure virDomainXMLConf that
will contain immutable data that are used by the XML parser. This will
allow two things we need:

1) Get rid of the stuff from virCaps

2) Allow us to add callbacks to check and add driver specific stuff
after domain XML is parsed.

This first attempt removes pointers to private data allocation functions
to this new structure and update all callers and function that require
them.

b090aa7d55 Introduce a virQEMUDriverConfigPtr object
Currently the virQEMUDriverPtr struct contains an wide variety
of data with varying access needs. Move all the static config
data into a dedicated virQEMUDriverConfigPtr object. The only
locking requirement is to hold the driver lock, while obtaining
an instance of virQEMUDriverConfigPtr. Once a reference is held
on the config object, it can be used completely lockless since
it is immutable.

NB, not all APIs correctly hold the driver lock while getting
a reference to the config object in this patch. This is safe
for now since the config is never updated on the fly. Later
patches will address this fully.

c1509ab47e qemu: escape ipv6 for rbd network disk hosts
Hosts for rbd are ceph monitor daemons. These have fixed IP addresses,
so they are often referenced by IP rather than hostname for
convenience, or to avoid relying on DNS. Using IPv4 addresses as the
host name works already, but IPv6 addresses require rbd-specific
escaping because the colon is used as an option separator in the
string passed to qemu.

Escape these colons, and enclose the IPv6 address in square brackets
so it is distinguished from the port, which is currently mandatory.
