Daniel Stenberg c8b6119b38 Added weird circumvention macros for SIMULATOR builds. When we build a 
charcell LCD simulator, we keep the bitmap LCD functions too, as we use
the bitmap functionality to put characters on screen. But since the charcell
LCD api and the bitmap LCD api use the same function names for a few
functions, we include redef and undef files to fix that...
