decomp some small files, do some cleanup (#42)

* remove leftover asm: JSUList.s

* d_save_init: decomp

* JMath/random: decomp

* J3DUDL: fixup label

* JAUClusterSound: decomp

* c_API_controller_pad: decomp, elaborate globals/types

* clang-format

* don't add guards to functions.h

* semantic merge of m_cpadInfo stuff
