php: fix emalloc/efree/estrdup/... undefined references
zend_alloc.h defines some macros such as: Where _estrdup is the actual function implemented by the PHP core. If this header file is not included, and some code uses estrdup, one ends up with an undefined reference. This happens when libexpat support is enabled. This commit adds a PHP patch that fixes this issue. The patch has been submitted upstream through a Github pull request.

+Subject: [PATCH] ext/xml/expat_compat.h: add missing php.h include
+
+When expat support is disabled and libxml support is enabled, the
+following part of the code in expat_compat.h gets used:
+
+and therefore "php".h" is included. However, when libexpat support is
+enabled, HAVE_LIBEXPAT is defined, and therefore the following part of
+the code is used:
+
+In this case, "php.h" is not included. Due to this, zend_alloc.h is
+never included when building the ext/xmlrpc/libxmlrpc/xml_element.c
+file, and therefore the estrdup -> _estrdup macros are never defined,
+causing the following link time failure:
+

+We fix it by including "php.h" in the HAVE_LIBEXPAT case.
