Add support to xenconfig for conversion of xl.cfg(5) bios config
to/from libvirt domXml <loader> config. SeaBIOS is the default
for HVM guests using upstream QEMU. ROMBIOS is the default when
using the old qemu-dm. This patch allows specifying OVMF as an
alternate firmware.
Example xl.cfg:
bios = "ovmf"
Example domXML:
<os>
...
<loader readonly='yes' type='pflash'>/usr/lib/xen/boot/ovmf.bin</loader>
</os>
Note that currently Xen does not support a separate nvram for
non-volatile variables.

All the accesses to files outside our build or source directories
are now identified and appended into a file for later processing.
The location of the file that contains all the records can be
controlled via VIR_TEST_FILE_ACCESS env variable and defaults to
abs_builddir "/test_file_access.txt".
The script that will process the access file is to be added in
next commit.

This was only used for test 'xml blanking', which has now all
been removed, and isn't an ideal paradigm anyways since it
inhibits easy XML regeneration.
This patch enable regeneration of expected output file for
virTestDifferenceFull. It also introduces new
virTestDifferenceFullNoRegenerate function for special cases, where we
don't want to regenerate output.

virtTestResult is suboptimal for a few reasons:
- It poorly duplicates virtTestRun pass/fail reporting logic
- It doesn't have virtTestRun's alloc testing support
- It only reports the test name _after_ the test has run.
- It doesn't follow the standard virtTestRun pattern that most other
tests use.
There's no users left, so drop it. If any other async tests like eventtest
spring up that don't cleanly fit the virtTestRun pattern, I suggest they
just open code the support for it around virtTestRun
Adding or reordering test cases is usually a pain due to static test
case names that are then passed to virtTestRun(). To ease the numbering
of test cases, this patch adds two simple helpers that generate the test
names according to the order they are run. The test name can be
configured via the reset function.
This will allow us to freely add test cases in middle of test groups
without the need to re-number the rest of test cases.
To simplify looking for a problem instrument the XML comparator function
with possibility to print the filename of the failed/expected XML
output.
This is necessary as the VIR_TEST_DIFFERENT macro possibly tests two XML
files for the inactive/active state and the resulting error may not be
obvious.
Using the virCommand dry run capability, capture iptables rules
created by various network XML documents.

The virDomainGetRootFilesystem method can be generalized to allow
any filesystem path to be obtained.
While doing this, start a new test case for purpose of testing various
helper methods in the domain_conf.{c,h} files, such as this one.

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

While trying to debug a failure of virpcitest during 'make distcheck',
I noticed that with a VPATH build, 'cd tests; ./virpcitest' fails for
an entirely different reason. To reproduce the distcheck failure, I
had to run 'cd tests; abs_srcdir=/path/to/src ./virpcitest'. But we
document in HACKING that all of our tests are supposed to be runnable
without requiring extra environment variables.
The solution: hardcode the location of srcdir into the just-built
binaries, rather than requiring make to prepopulate environment
variables. With this, './virpcitest' passes even in a VPATH build
(provided that $(srcdir) is writable; a followup patch will fix the
conditions required by 'make distcheck'). [Note: the makefile must
still pass on directory variables to the test environment of shell
scripts, since those aren't compiled. So while this solves the case
of a compiled test, it still requires environment variables to pass
a VPATH build of any shell script test case that relies on srcdir.]
* tests/Makefile.am (AM_CFLAGS): Define abs_srcdir in all compiled
tests.
* tests/testutils.h (abs_srcdir): Quit declaring.

Multiple tests need to register a function to quiesce errors from
libvirt when using a connection and doing negative tests. Each of those
tests had a static function to do so. This can be replaced by a utility
function that enables the errors when debug is enabled.
This patch adds virtTestQuiesceLibvirtErrors() and refactors test that
use private handlers.
The logic set up in previous patch for exposing VIR_TEST_EXPENSIVE
to individual tests is as follows:
make check VIR_TEST_EXPENSIVE=0 => getenv("VIR_TEST_EXPENSIVE") sees "0"
make check VIR_TEST_EXPENSIVE=1 => getenv("VIR_TEST_EXPENSIVE") sees "1"
make check => getenv("VIR_TEST_EXPENSIVE") sees
either "0" or "1", based on configure options
cd tests; ./FOOtest => getenv("VIR_TEST_EXPENSIVE") sees
whatever is in your environment (usually NULL, but possibly garbage)
Merely checking if VIR_TEST_EXPENSIVE is set in the environment
does the wrong thing; likewise, it is unsafe to assume the
variable will always contain a valid number.
As such, it helps to have helper functions, instead of making each
expensive test repeat the probe of the environment.

* tests/testutils.c (virTestGetExpensive): Implement it.
* tests/test-lib.sh (very_expensive_): Rename...

Commit a2619962 introduced virFilePrintf to work around the fact
that gnulib doesn't (yet) provide guarantees about fprintf() vs.
%z, which in turn causes all sorts of mingw compilation errors:
../../tests/testutils.c: In function 'virtTestResult':
../../tests/testutils.c:101:9: error: unknown conversion type character 'z' in format [-Werror=format=]
fprintf(stderr, "%3zu) %-60s ", testCounter, name);

Rather than s/fprintf/virFilePrintf/ (and reformatting loads of
lines) across multiple files, it's easier to just hack the entire
testsuite to take advantage of our helper function.

This test case validates the correct generation of SELinux labels
for VMs, wrt the current process label. Since we can't actually
change the label of the test program process, we create a shared
library libsecurityselinuxhelper.so which overrides the getcon()
and setcon() libselinux.so functions. When started the test case
will check to see if LD_PRELOAD is set, and if not, it will
re-exec() itself setting LD_PRELOAD=libsecurityselinuxhelper.so
