73bf0a9c28 backup: Prepare for Unix sockets in QMP nbd-server-start
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
the monitor calls, since that is a nice reusable struct that can track
both TCP and Unix sockets.

Update qemumonitorjsontest to verify both forms of the QMP command.

1ddc7e0363 qemumonitorjsontest: Simplify returns
Time to remove the cleanup labels rendered useless in the previous
patch.  There are still plenty of other tests that could be further
simplified, but I've already spent enough time in this file for now.

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:

4cfd709021 Fix many mistakes & inconsistencies in header file layout
This introduces a syntax-check script that validates header files use a
common layout:

  /*
   ...copyright header...
   */
  <one blank line>
  #ifndef SYMBOL
  # define SYMBOL
  ....content....
  #endif /* SYMBOL */

For any file ending priv.h, before the #ifndef, we will require a
guard to prevent bogus imports:

  #ifndef SYMBOL_ALLOW
  # error ....
  #endif /* SYMBOL_ALLOW */
  <one blank line>

The many mistakes this script identifies are then fixed.

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.
