[devel] Freeze build-time only configuration in the build. In all prior versions of libpng most configuration options controlled by compiler #defines had to be repeated by the application code that used libpng. This patch changes this so that compilation options that can only be changed at build time are frozen in the build. Options that are compiler dependent (and those that are system dependent) are evaluated each time - pngconf.h holds these. Options that can be changed per-file in the application are in png.h. Frozen options are in the new installed header file pnglconf.h
