ape/ctype.h: add isblank, fix functions (thanks staalmannen)
Our ctype.h mistakenly ommitted isblank. Add it in.
While we're here, the make the 'isfoo()' functions
are broken: they're offsetting into the array, and
don't work with negative character values.
Sync the function bodies with the macros, and make
them produce correct results.
