Pica: Cleanup clipping code and change screenspace z to range from -1..0.
...
The change in depth range seems to reflect better to what applications are expecting, and makes for cleaner code overall (hence is more likely to reflect hardware behavior).

Asserts: break/crash program, fit to style guide; log.h->assert.h
...
Involves making asserts use printf instead of the log functions (log functions are asynchronous and, as such, the log won't be printed in time)
As such, the log type argument was removed (printf obviously can't use it, and it's made obsolete by the file and line printing)
Also removed some GEKKO cruft.

GSP: Update framebuffer info on all interrupts
...
Hardware testing determined that the GSP processes shared memory
framebuffer update info even when no memory transfer or filling GX
commands are used. They are now updated on every interrupt, which isn't
confirmed correct but matches hardware behaviour more closely.
This also reverts the hack introduced in #404 . It made a few games
behave better, but I believe it's incorrect and also breaks other games.

Clipper: Compact buffers on each clipping pass
...
Use a new buffer management scheme in the clipper that allows using a
bounded minimal amount of buffer space. Even though it copies more data
it is still slightly faster likely due to using less cache.

Clipper: Avoid dynamic allocations
...
The triangle clipper was allocating its temporary input, output and work
buffers using a std::vector. Since this is a hot path, it's desirable to
use stack allocation instead.
