The built-in `print` is removed from jerry-core, but an external `print` implementation is added to jerry-main. From now on, all embedders of the engine have to implement their own `print` if they need such a functionality. For printing results in REPL mode of jerry-main, the external `print` handler is called directly instead of looking up the `print` function registered into the global object. (The two are the same, but the indirection is not needed anymore.) Because jerry-core does not contain `print` anymore, `jerry_port_console` is removed from the port API. The default port is updated, i.e., the implementation of `jerry_port_console` is removed. Additionally, all references to `jerry_port_console` in jerry-main are replaced by `printf`. Speculatively, `jerry_port_console` is also removed from all non-default targets. Most targets implemented it for the sake of the engine only; in those targets the removal was trivial. Where the function was called from the embedder application as well, the calls were replaced with equivalents (e.g., `printf`, `printk`). NOTE 1: This is a breaking change! NOTE 2: This patch still leaves several targets without a JS `print` implementation. JerryScript-DCO-1.0-Signed-off-by: Akos Kiss akiss@inf.u-szeged.hu
