mg_assemble_uri()	mg_assemble_uri	func	int mg_assemble_uri(const struct mg_str *scheme, const struct mg_str *user_info, const struct mg_str *host, unsigned int port, const struct mg_str *path, const struct mg_str *query, const struct mg_str *fragment, int normalize_path, struct mg_str *uri);

Assemble URI from parts. Any of the inputs can be NULL or zero-length mg_str.

If normalize_path is true, path is normalized by resolving relative refs.

Result is a heap-allocated string (uri->p must be free()d after use).

Returns 0 on success, -1 on error.
