Crucial, missing things.
! core: the four basic memory functions
exc: add exception handlers, use them in the DMA This change introduces exception handlers that default to a fatal error with an on-screen description of the exception and some debugging information. It also adds the dprint() function as a definitely-needed helper and removes bootlog_unmapped() by using the exception handler for the fatal error display. (Also printf() is now required in all gint add-ins; this is sad, but space is not as much of a constraint as debugging.) Finally, the exception handler is used to handle an interrupt which is an exception in practice, the DMA address error. On fx-CG 50, additional DMA-related information is displayed on the screen. This is left out on fx-9860G as there is not enough space.

* make fx9860g projects work out of the box on fxcg50
core: allow custom panics and exception catching This change introduces two new mechanismes for executing user code when an exception occurs. * This first is the custom panic message, which usually displays "System ERROR". The function that performs this task can now be user-defined. It is also run in user mode because the exception handler rte's into it, allowing it to execute any kind of interrupt-inducing task. The behavior is undefined if this function raises an exception. * The second is an exception-catching function, which (when set) is called every time an exception occurs, and is granted the chance of handling the exception to continue execution normally. It can be used in various ways, the most primitive of which is recording the exception and going back. It runs in interrupt mode and must not raise any kind of exception.
