First decompile attempt. code_800AF9B0 (#121)

* Decompile a couple code_800AF9B0 functions

* Match func_800B34E8, func_800B44AC, and func_800B45E0

* Use sizeof in func_800B45E0 instead of hard-coded numbers

* Match func_800B4520. Separate unused function func_800B4560 into new asm file

* Match func_800B5B2C and func_800B6A68. Create new unused func_800B6AF8

* Match func_800B4874 and func_800B4A10

* Improve matched functions reading time trial records

* Match func_800B13B0. Name variables related to data menu

* Match func_800B3B58. Remove warnings due to pointer type in osEepromLongWrite calls

* Rename gStartMenuCounterForDemos to gMenuTimingCounter

* Match func_800B5F30
