@brief Caches reply information from QueryExtension requests.
@param c: The connection.
@param ext: The extension data.
@return A pointer to the xcb_query_extension_reply_t for the extension.
This function is the primary interface to the "extension cache",
which caches reply information from QueryExtension
requests. Invoking this function may cause a call to
xcb_query_extension to retrieve extension information from the
server, and may block until extension data is received from the
server.
The result must not be freed. This storage is managed by the cache
itself.
