[PATCH 00/11] Improve charset and cid: handling

[Austin Clements]

I added declare-functions for both of these, which should take care of
the Emacs 23 warnings and be more robust on Emacs 24.  We can't reach
the function that calls these unless shr is actually available, but the
byte compiler doesn't know that.
