Restructure meta files

* Move "COPYING" and "Changelog" from "meta/" to the top-level source
  directory. No need to have a separate directory for two small text
  files. Also, it's common practice to put these there.

* Makefile: Merge "meta/Makefile".

* Rename "Changelog" to "NEWS". The file containing a summary of changes
  between two releases in generally called "NEWS". The name "ChangeLog"
  should only be used for a detailed log of every commit.
