[libpng16] Fixed previous support for Z_PREFIX in configure builds, corrected

Browse Source 
sCAL APIs; some of these use floating point arithmetic so they need to be
disabled if floating point arithmetic is switched off.  This is a quiet API
change - previously it appeared that the APIs were supported if fixed point
arithmetic was used internally, however they required certain APIs (floor,
modf, frexp, atof) that are part of C floating point support. Changed
png_fixed and the gamma code specific version of the same to avoid floor(),
which may be a library function (not an intrinsic). Removed unused #if 0
code.
