a7b4eb7d26 virfiletst: Test virFileIsSharedFS
Introduce some basic test cases for virFileIsSharedFS(). More
will be added later. In order to achieve desired result, mocks
for setmntent() and statfs() need to be invented because the
first thing that virFileIsSharedFS() does is calling the latter.
If it finds a FUSE mount it'll call the former.

The mock might look a bit complicated, but in fact it's quite
simple. The test sets LIBVIRT_MTAB env variable to hold the
absolute path to a file containing mount table. Then, statfs()
returns matching FS it finds, and setmntent() is there just to
replace /proc/mounts with the file the test wants to load.

Adding this test also exposed a bug we have - because we assume
the given path points to a file we cut off what we assume is a
file name to obtain directory path and only then we call
statfs(). This is buggy because the passed path could be already
a mount point.

9cf38263d0 Switch from yajl to Jansson
Yajl has not seen much activity upstream recently.
Switch to using Jansson >= 2.5.

All the platforms we target on https://libvirt.org/platforms.html
have a version >= 2.7 listed on the sites below:
https://repology.org/metapackage/jansson/versions
https://build.opensuse.org/package/show/devel:libraries:c_c++/libjansson

Additionally, Ubuntu 14.04 on Travis-CI has 2.5. Set the requirement
to 2.5 since we don't use anything from newer versions.

Implement virJSONValue{From,To}String using Jansson, delete the yajl
code (and the related virJSONParser structure) and report an error
if someone explicitly specifies --with-yajl.

Also adjust the test data to account for Jansson's different whitespace
usage for empty arrays and tune up the specfile to keep 'make rpm'
working when bisecting.

f50ad2ff63 tests: Link mocks with libvirt.so
In a lot of our mocks (if not all of them) we use our internal
APIs (e.g. VIR_ALLOC). So far, we're relying on test binary that
links with the mock to drag in libvirt.so. Well, this works only
partially. Firstly, whatever binary we execute from tests will
fail (e.g. as Martin reported on the list ./qemucapsprobe fails
to execute qemu). Secondly, if there's a program that tries to
validate linking (like valgrind is doing) it fails because of
unresolved symbols.

Because of that we have to link our mocks with libvirt.so.

a455d41e3e conf: expand network device callbacks to cover resolving NIC type
Currently the QEMU driver will call directly into the network driver
impl to modify resolve the atual type of NICs with type=network. It
has todo this before it has allocated the actual NIC. This introduces
a callback system to allow us to decouple the QEMU driver from the
network driver.

This is a short term step, as it ought to be possible to achieve the
same end goal by simply querying XML via the public network API. The
QEMU code in question though, has no virConnectPtr conveniently
available at this time.

Since update to glibc-2.26 removed the /usr/include/rpc/rpc.h we used until now,
it showed us a problem with not using XDR_CFLAGS properly.  On linux that
variable has usually -I/usr/include/tirpc because we already probe for it
properly, we just don't use it everywhere we need.  It is needed by wireshark
dissector as well as testutilsqemu.c (through includes) so the build fails with:

wireshark/src/packet-libvirt.c:33:10: fatal error: rpc/xdr.h: No such file or directory
 #include <rpc/xdr.h>

Since lot of tests use testutilsqemu.c it is easier to add XDR_CFLAGS to

eae746b2d7 Stop linking tests/commandhelper to libvirt code
The commandhelper binary is a helper for commandtest that
validates what file handles were inherited. For this to
work reliably we must not have any libraries that leak
file descriptors into commandhelper. Unfortunately some
versions of gnutls will intentionally open file handles
at library load time via a constructor function.

We previously hacked around this in

  commit 4cbc15d037
  Author: Martin Kletzander <mkletzan@redhat.com>
  Date:   Fri May 2 09:55:52 2014 +0200

    tests: don't fail with newer gnutls

    gnutls-3.3.0 and newer leaves 2 FDs open in order to be backwards
    compatible when it comes to chrooted binaries [1].  Linking
    commandhelper with gnutls then leaves these two FDs open and
    commandtest fails thanks to that.  This patch does not link
    commandhelper with libvirt.la, but rather only the utilities making
    the test pass.

    Based on suggestion from Daniel [2].

    [1] http://lists.gnutls.org/pipermail/gnutls-help/2014-April/003429.html
    [2] https://www.redhat.com/archives/libvir-list/2014-April/msg01119.html

That fix relied on fact that while libvirt.so linked with
gnutls, libvirt_util.la did not link to it.  With the
introduction of the util/vircrypto.c file that assumption
is no longer valid. We must not link to libvirt_util.la
at all - only gnulib and libc can (hopefully) be relied
on not to open random file descriptors in constructors.

d8e8b63d30 libxl: Add a test suite for libxl_domain_config generator
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.

478f0c5b85 tests: add virfilecachetest
