[Maintenance] Export all pascal functions with their proper uppercase names Yup, that was one massive screw-up. Part of P0030, funded by zorg.

[Reverse-engineering] [th04/th05] .BB file loading boilerplate Yup, nothing interesting in here. Except for maybe the confirmation that LS00.BB is used for the curved bullets used by Shinki and EX-Alice? Funded by -Tom-.

[Maintenance] Use the same resident structure pointer name for every game The TH04/TH05 BGM/SE mode setup is a good example for code where different structure field offsets will vanish completely upon reverse- engineering. If we continued to use the per-game ID string as the variable name, we'd only have another game-specific "difference" there. Part of P0065, funded by Touhou Patch Center.

[Maintenance] Fix the function name format of CDG/CD2 functions No leading underscore for functions with Pascal calling convention, but we do have one for all variables, because it's not worth it to put keywords in front of everything for no reason. Seemed to have forgotten this rule in 2017? Part of P0030, funded by zorg.
