[libpng16] Added PNG_SAFE_LIMITS feature to pnglibconf.dfa, pngpriv.h, and new pngusr.dfa

Browse Source 
to reset the user limits to safe ones if PNG_SAFE_LIMITS is defined.
To enable, use CPPFLAGS=-DPNG_SAFE_LIMITS on the configure command
or put #define PNG_SAFE_LIMITS_SUPPORTED in pnglibconf.h.prebuilt.
(Reverted previous implementation of PNG_SECURE.)
