* Fix some AVOID_UB stuff, and some small documenting.

* Fix m2ctx.py and add NON_EQUIV func_80045C48

* Minor issue cleanups

* Clean up audioline_ambient_create match

* Match func_80008040 as audioline_init, fix the generate ctx script, and some small warning stuff.

* Minor work on func_80008174 so it can be NON_EQUIVALENT again

* redefine asm abs

* Hackishly fix the ctx file when generated.

* Use some more constants and got rid of some start: auto stuff which is not recommended in splat anymore for BSS
