07772cba07 [libpng15] Fixes for multiple calls to png_read_update_info. 
These fixes attend to most of the errors revealed in pngvalid, however doing
the gamma work twice results in inaccuracies that can't be easily fixed.
There is now a warning in the code if this is going to happen.

b2bee3374c [devel] Make the 16-to-8 scaling accurate. Dividing by 256 with no rounding is 
wrong (high by one) 25% of the time. Dividing by 257 with rounding is
    wrong in 128 out of 65536 cases. Getting the right answer all the time
    without division is easy.

c5bef946b1 [devel] IDAT compression failed if preceded by a compressed text chunk 
This was because the attempt to reset the zlib stream in png_write_IDAT
happened after the first IDAT chunk had been deflated - much too late.
In this change internal functions are added to claim/release the z_stream
and, hopefully, make the code more robust.  Also deflateEnd checking is
added - previously libpng would ignore an error at the end of the stream.

John Bowler
88b77cc6f3 [devel] Remove png_snprintf, add formatted warning messages. 
This change adds internal APIs to allow png_warning messages to have parameters
 without requiring the host OS to implelment snprintf.  As a side effect the
 dependency of the RFC1132 code on stdio is removed and PNG_NO_WARNINGS does
 actually work now.
