z_bgcheck.c (#357)

* first few functions

* two more almost matching functions

* Rebase to NBS, get it to compile

* BgCheck_RaycastFloorStaticList OK, fix-up some functions

* BgCheck_SphVsStaticWall OK! and a few others

* more z_bgcheck NON_MATCHINGS

* OK more functions, reorganize external reference #defines

* More functions OK, more struct fixes

* More OKs

* Decomp all the way to the end of bgcheck

* All functions attempted

* Rename functions

* formatting, data migration

* Give names to unk structs, rename some structs, fix some non-equivalent functions

* WaterBox_GetSurfaceImpl OK

* BgCheck_ResetPolyCheckTbl OK, improve WaterBox_GetSurface2 codegen, eliminate warnings and clean up source.

* BcCheck3_BgActorInit ->BgCheck3_BgActorInit, fix warnings

* pr change requests

* fix crc maybe

* implement more changes

* implement alf's changes
