1e2ae2e311 Use g_autofree instead of VIR_AUTOFREE
Since commit 44e7f02915
    util: rewrite auto cleanup macros to use glib's equivalent

VIR_AUTOFREE is just an alias for g_autofree. Use the GLib macros
directly instead of our custom aliases.

fde361083d tests: Add lib- prefix to all mocks
In preparation libtool "-module" flag removal, add lib prefix to all
mock shared objects.

While at it, introduce VIR_TEST_MOCK macros that makes path out of mock
name to be used with VIR_TEST_PRELOAD or VIR_TEST_MAIN_PRELOAD.  That,
hopefully, improves readability, reduces line length and allows to
tailor VIR_TEST_MOCK for specific platform if it has shared library
suffix different from ".so".

Migration always uses a TCP socket for NBD servers, because we don't
support same-host migration. But upcoming pull-mode incremental backup
needs to also support a Unix socket, for retrieving the backup from
the same host. Support this by plumbing virStorageNetHostDef through

both TCP and Unix sockets.

4b658bfe4b qemumonitorjsontest: Validate more commands against schema
The DO_TEST() macro in qemumonitorjsontest.c was not passing the
schema through, which meant that we were not validating any of those
tests for correct usage according to the schema.

In the process of mechanically altering tests to pass the schema
through, use VIR_AUTOPTR on all of the affected test instances. The
next patch will do some further cleanups that it exposes.

Tested by using this hack, where the test mistakenly passed pre-patch,
but correctly diagnosed the garbage post-patch:

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.
