gint: compressed VRAM save on fx-CP
This frees the OS' backup VRAM, which is a 337920-byte buffer sitting
at a fixed address, for loading code.

meta: add LTO support and enable it by default
* Set -flto
* Use gcc-ar to build the archive so the LTO plugin is loaded and LTO
  sections aren't stripped off the object files
* Slightly conservative KEEP()s in the linker script (not required but
  I'm paranoid)
* Make the drivers __attribute__((externall_visible)) so they are
  generated by the link-time back-end and not left in the archive
* Remove the unused isappli/optnum parameters of main, which have been
  unused for years, are irrelevant on fx-CG and lead to a link-time
  warning with LTO. I'll add APIs to access them later.

cmake: make the linker script a link dependency of projects
This way when we update the linker script in the upcoming LTO support
commit, it will be used automatically without a full rebuild.

cpu: also save rN_bank registers at startup/exit
These are at least used on the CP to hold OS-related interrupt handler
pointers (to handling routines).

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.

gdb, video, r61524: gdb visual feedback + start video intf on CG
- Define a draft of the video interface
- Implement that dragt for CG for a single mode
  * Includes stub of brightness setting from disassembling 3.60
- Use the video interface to show visual feedback on GDB on CG

Using the video interface avoids directly linking into a driver, which
will serve modularity in gint 3.

gdb: support 'C' packet for resuming with signals
It's not super useful as a feature but it means that a naive "continue"
after e.g. a segfault will kill the program and not confusingly go into
an infinite loop.

gdb: allow gdb stub to automatically start when a crash occurs
The user can still gdb_start() + gdb_main(NULL) manually, which allows
e.g. early setup of breakpoints. The start_on_except mechanism is the
lazier method where we just run the add-in normally and start fxsdk gdb
on the PC *after* a crash occurs.

ubc: slight cleanup
It is guaranteed by the driver model that drivers are powered on when
gint is active. Sharing the driver isn't too useful because we can't
remote debug in the OS world anyway, there's no USB driver there.

gint: switch away from FX9860G/FXCG50 macros
Not changing much for now, just distilling them into hardware/OS/render
macros. Later on the rendering stuff will become more dynamic and down
the line I want to unify the APIs more.

gint: switch from file filters to config macros + basic fxg3a target
Nothing interesting in this commit, just moving files around, making
sure every target compiles every file, and controlling with macros
instead.

Basic support for fxg3a target in CMakeLists.txt, cmake/FindGint.cmake,
giteapc.make and include/gint/config.h.in. The rest is forgettable.

render: parametrize existence of dmode in config.h
This is the first of many steps designed to reduce gint's reliance on
the FX9860G and FXCG50 macros by describing the compile target more
symbolically. The goal is to allow both for g3a compilation of fx-API
code and for a potential CP port.

render-fx: turn bopti_image_t's data array into a pointer
It used to be a flexible array member because in the old days fxconv
could only output a fixed set of bytes, so any referencing was out the
question. Nowadays fxconv can output pretty much anything. Separating
the data pointer will be useful for PythonExtra to expose it as a Python
bytes() or bytearray() object while using the gint API.

gint: avoid annoying banner on return from menu on fx-CG
Instead of using GetKeyWait(), we directly call into an internal OS
function, which avoids the need to press a key before we can redraw over
the OS banner and VRAM when coming back. The disassembly to locate the
function was developed by Dr-Carlos.

We still have to redraw when coming back; getkey() will do it by
dupdate() by default, and it that's not a possibility for the
application an option to receive a special event and handle it manually
is provided.
