some work on extreme/degenerate shit in GPU
...
* clip against Z then Y then X. apparently, fixes #310 . I had also observed hints that the hardware does it this way.
* truncate W to 24 bits before viewport transform.
* mark any polygons that have a W=0 at that point as degenerate. do not render.

set GXSTAT busy flag immediately when writing a command to the GXFIFO.
...
there was a slim chance that a game could send a couple commands and read GXSTAT.busy as zero immediately after. the new timings made that happen in NSMB (not in the USA ROM, oddly), such that the game was reading the clip matrix while matrix commands were running, and getting the first few values wrong.
fixes #295 and probably others in the same vein.

begin work on general timing renovation. way shitty because it behaves as if caches were off, so everything will be slow as shit.

* fix possible issues with GXFIFO stalling
...
* rework GPU timings, now almost same as hardware. display lists generally execute faster. not finished. not bad for a start tho.
* Rayman RR2 is still getting sound streaming issues. I don't think GXFIFO stalls are supposed to halt the ARM7. that doesn't make sense and would mess badly with sound since it's also using the ARM7 bus.

bad games that blast the GXFIFO and overflow it:
* Super Mario 64 DS
* Rayman RR2
latter seems to get its music streaming crapoed.

* store all 32 matrix stack entries in savestates instead of 31.
...
* bump savestate version up. will break compatibility, but the alternative would be guessing the missing matrix entries somehow, so blarg.
* avoid relocating the savefile if loading a savestate fails.

rewrite how structures are stored to savestates (store individual fields, to avoid compatibility issues)
...
also fixes stability issues when 3D is involved. turns out we were storing raw pointers to vertices. figures
more crapo code to get around that, but atleast it works without asploding now.
