Cleanups for FAPI functions
Fix .FAPIAvailable to check for stack underflow
Undefine FAPI functions at end of gs_fapi.ps
(.FAPIavailable, .FAPIpassfont, .FAPIrebuildfont)
The rendering functions, .FAPIBuildGlyph, .FAPIBuildChar, .FAPIBuildGlyph9,
are still defined. I noticed similar rendering funcs for other fonts are also
exposed -- not sure if this is fixable or not.
