One day, I could not resist the way it was written. I finally started to make the code clean. This changeset is the beginning of a series of housekeeping commits. It is a simple refactoring; split internal.h into files, so that we can divide and concur in the upcoming commits. No lines of codes are either added or removed, except the obvious file headers/footers. The generated binary is identical to the one before.
