Move duplicated documentation rules to Makefile.shared

- Also, harmonize libm to use CHEWOUT_FILES like libc, rather than chobj.
  Update documentation appropriately.

 In summary, to add new documentation:
 
 1.  Add properly-formatted comments to source file (e.g. src.c);
-2.  add "chewout" file to list in Makefile.am (CHEWOUT_FILES in libc or chobj in
