gint: basic support for fx-CP 400 programs with HollyHock 2 loading
Features will come in slowly while I restructure for gint 3. With this third big target for gint, the legacy aspects of gint 2's structure and API are getting felt, so a major revision will be in order. See the TODO file at this commit for info on what works and not.

fx-CP port progress.

DONE:

- kernel can start add-ins, take over interrupts (but no interrupt sources yet)
|

- panic handler works (no interactive choices, only RESET)
|

- no OS menu (likely never) and poweroff (maybe later)
|

- memory: 64 kB total + OS heap (no gint arena, no MMU)
|
||||
- r61523: prototype display driver
|

- can use the rendering pipeline with no DMA acceleration

- unification of the image/video interface

- quit handler

- keyboard and touch screen input

- drivers: cpg, dma, intc, rtc, tmu

- find more memory, 64 kB is not enough

- benchmark memory and display performance

- improve API and performance of display driver
