z_bgcheck.c, 800430A0.c, 80043480.c (#256)
* beginning of migrating changes

* got matching

* changed order a bit

* clean up bgcheck

* fix conflict

* fix conflict again

* first stab at identifying types, some oks

* Clean up most bad structs/pointer math, move relevant structs to z64bgcheck.h, get some OKs

* more OKs, z_bgcheck.bss migration, update some sys_math3d.c args

* couple more OKs

* pushing some OKs

* fix compilation issues

* code_800430A0.c OK, more files decomp'd

* 8003A3E0 big OK :)

* Decomp most of func_8003C614, decomp helper funcs

* Decomp SurfaceType, CamData, and WaterBox property related functions

* more OKs, big OK in 8003C078

* more OKs, more progress, move a function definition in z_collision_check to functions.h

* more clean-ups, more OKs, dyn_vtx is now defined as u8*

* 8003A5B8, 8003A7D8, 8003C614, 8003DD6C OK, document function args better

* data migrated, more OKs

* 80041240 OK, func_8003B3C8 and func_8003BB18 disassembled

* func_80040284, 800409A8 non_matching, add IS_ZERO macro

* All asm files have C representations, some big OKs, lots of minor tweaks

* More OKs, non-matching code cleanup

* 8003FBF4 and 80040BE4 OK, improve codegen for most functions

* format z_bgcheck.c

* fix warnings, compile errors on NON_MATCHING

* func_8003EE80 is now NON_MATCHING

* begin documenting some functions

* formatting

* more documentation, func_8003A95C OK

* fix PHYSICAL_TO_VIRTUAL changes

* fix var rename

* More documentation, functions 80040E40, 80041648 OK, change types to not be compatible with ZAP

* func_8004239C ok, more NON_MATCHING improvements, more documentation

* Implement most suggested changes

* Convert comments to slower comments

* /**

* Implement ZAP2 changes

* my anti-virus ate my format.sh results

* Rename a couple hundred functions, fix minor stuff

* rename var so that clang formats correctly

* run format.sh

* implement Petrie's matches/suggestions

* format

* matches

* and the asm

* slight error

* Add SSList

* two more matches

* stuff

* implement code changes

* clean up Petrie's matchings
