speakup: Generate speakupmap.h automatically
speakupmap.h was not actually intended to be source code, speakupmap.map is. This resurrects the makemapdata.c and genmap.c tools to generate speakupmap.h automatically from the input and speakup headers, and the speakupmap.map keyboard mapping source file.
