c_lib: Decomp a few functions (#89)

* c_lib: Decomp cLib_memSet and cLib_memCpy

Gets rid of some low-hanging fruit.

* c_lib: Decomp cLib_distanceAngleS

Another super trivial function to make match.

* c_lib: Decomp cLib_targetAngleY overload set

Fairly trivial in terms of matching.

* c_lib: Sate clang-format

I didn't touch this code, but the clang-format pass wants this done, and
so it is.
