  more patches from Seth F, for the CHARSXP hashing
  Seth says:
  This patch series teaches R_StringHash how to handle the encoding
  information stored in the general purpose bits of CHARSXPs. A new
  interface for CHARSXP creation is added, mkCharEnc that allows for
  specifying the encoding.
  
  The patch series also captures more CHARSXPs in the global cache. In
  particular, character.c:mkChar2 and gram.y:mkChar2 both use the cache
  now.
  
  The string hashing in scan.c has been removed as it no longer is
  needed.
  
  The CallocCharBuf macro gets a small fix (extra parens)
  
  And last, but not least:
  
  CHAR() from package code now returns (const char *)
  
  Since CHARSXPs should no longer be modified in place, we can make
  CHAR() return (const char *) so that compilers can warn or error about
  improper modification. Thanks to Herve Pages for the suggestions.
