php: security bump to version 5.3.13 and enhance

Bump php to version 5.3.13 to solve multiple CVEs.
The 5.2 series is no longer maintained.

The PCRE and SPL extensions are no longer optional.
Reflection is no longer optional either.

Ncurses was spun out to PECL.

Add a ton of new extensions and give more granular options on others
(like the libxml2-based ones).

The FastCGI option no longer exists, it's always on as long as CGI is.
