magic: import and decompile hadoho, shaku, re_do

[j3lee]

Three spell overlays built from the same code, imported and fully decompiled (48 functions, no assembly left). One commit per overlay, then the names.

• hadoho and shaku differ in one call argument and one frame number
• re_do has the same structure with more differences
• the file named HADOHO (波動砲, Wave Artillery) is loaded for Dragon Cannon, and Wave Artillery itself uses SHAKU; the header of hadoho.c says so

The files are written to read alike, so a diff between two of them shows only the real code differences.

Each file opens with the attack it belongs to, in the form the other magic files use; an effect several attacks share lists them. Functions are named <Overlay><Thing><Verb> after what they draw or do (the sprite frames were decoded from each overlay to check the words); data keeps its D_ names. No shared header is changed.
