implement full support and usage of phar stream in include_path, for both 5.2 and 5.3.
5.3 code expects the proposed patch for stream wrapper in include_path to be committed
5.2 code only supports phar stream wrapper in include_path.
this is a 2-step process.  After this, more magic, particularly in funcinterceptors.c will be
converted to use phar_resolve_path, which is far safer than the current implementation.

this needs windows and 5.2 testing unix/windows
