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

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. Chuck Roydhouse (1): add arginfo for libvirt_domain_block_commit and libvirt_domain_block_job_info Frederic Mora (1): Add more tests Neal Gompa (2): Commit short instructions to using the php extension build method Bump version to 0.5.2 Remi Collet (28): add config.m4 to allow standard PHP extension build system include config.h earlier add missing arginfo (wip) fix typo in config.m4 add missing arginfo, part 2 adapt RETURN_STRING work on zpp register + fetch resources + hash adapt add_assoc_string_ex clean ALLOC_INIT_ZVAL zend_hash_update add_next_index_string buildable with PHP 7 bump version 0.5.2-dev fix zpp fix missed (hidden) zpp calls fix PHP 5 compat fix libvirt_version + add test port test-connect.phpt to real phpt Switch all add_assoc_string_ex to add_assoc_string to avoid nul char management Fix max_connections management add test-conn-limit.phpt (as real phpt) add test-connect-get-emulator.phpt fix parse_array + build warnings convert test-install.phpt to real phpt convert test-domain-create-and-coredump.phpt to real phpt convert test-domain-create-and-get-xpath.phpt to real phpt fix PHP 5 compat again (nested macro issue) Vasiliy Tolstov (3): add some checks to prevent overflow add block_commit support and needed const add libvirt_domain_block_job_info
