Cleanup: Re-organize the process_normal files.

Cleanup: Re-organize the process_normal files.

I was originally thinking of having `process_X()` and such functions.
I created `process_normal()` functions as the standard functions to use.
I ended up not doing this but the `process_normal` use remained.

This is the first step into cleaning up the structure to a simpler naming system.
All this does is rename the files and anything using the files by name.
Changes to the functions will be in a follow up commit.
