Don't immediately panic when an OpenGL function pointer can't be loaded.

If the method is required it'll panic at the use site instead.
This should fix #4

First GTE implementation: RTPT, NCLIP, AVSZ3 and NCDS
...
We can now display the PlayStation logo.
Mostly ported directly from mednafen's code since no doc out there
seems to be completely accurate.
Added a test infrastructure to compare the GTE results with the
original console.

region.

Implemented gamepad emulation.
...
The timings are tweaked because it seems our emulator is too fast at
this point: the BIOS attempts to start a new request while the
previous one is still in progress. This will have to be fixed later as
we become more accurate.
Only the original digital controller is supported for now.
The frontend supports keyboard and controllers through SDL2 for input.

For now I cheat by pretending that the CD tray is open. This way the
BIOS bails out and doesn't attempt to run the game.

although it requires further testing.

Don't fetch instructions like data, use a separate path.
...
The two paths should be different in order to handle debugging
read/write watchpoints correctly (instruction fetch shouldn't trigger
them). Later on we'll also need different paths to handle the caches
correctly.

Refactor interconnect to use a generic load/store implementation

Instead of having word/halfword/byte implementations for load and

some reason.
