[libvirt] [libvirt-php PATCH 00/35] Add PHP7 support and unit tests

[Neal Gompa]

First, I apologize if this was sent twice to anyone. I had an error
in my git send-email configuration.

This patch set primarily adds support for PHP 7 to libvirt-php,
but also adds the capability for libvirt-php to be built
using the standard PHP extension build system method.

Several tests have been updated and added by Remi Collet (Fedora PHP stack maintainer)
and Frederic Mora (my colleague who graciously assisted in this effort).
I intend to provide more tests over time, but I think this is a good start.
These tests can be run through `make tests` in the new build system.
Instructions for using the new build system is also included.

The original build system still properly builds libvirt-php on
either PHP 5.6 or PHP 7.0. This was tested using Remi's PHP 5.6
and PHP 7.0 software collections on CentOS 7.2.

Most of this work was done by Remi Collet several weeks ago,
with Chuck Roydhouse doing work to ensure that Vasiliy Tolstov's
patches from the current git master could be incorporated into this work.
They are included in this patch set, but should be the same as what is
in the tree now. This work started before he posted his commits and
they were merged, and were merged in to ensure that it could remain
working.

The version number was bumped to 0.5.2 by Remi, and I bumped it in the
main build system simply for consistency.

I would greatly appreciate a quick review and merge of this patch set.
