uri: Remove php_uri_parse() and php_uri_free()
This API is both less powerful as well as less efficient compared to just calling the `->parse_uri()` handler of the parser directly. With regard to efficiency it needlessly allocates 32 byte of memory to store two pointers, of which one is already known, because it's the input. While it would be possible to just return the resulting `uri_internal_t` struct (instead of a pointer to a freshly allocated one), which would be returned as a register pair, users of the API can also just create the struct themselves for even more flexibility in allocations. The API is also less powerful, because it does not support base URIs.
