f1eafe8b01 Relax limit checks on gamma values. 
As suggested in the comments gamma values outside the range currently permitted
by png_set_alpha_mode are useful for HDR data encoding.  These values are
already permitted by png_set_gamma so it is reasonable caution to extend the
png_set_alpha_mode range as HDR imaging systems are starting to emerge.

98c6fa2495 PNG_IMAGE_PNG_SIZE_MAX error correction 
The macro underreported the size (by up to 512 bytes) of an 8-bit non-color
palette based memory format because it failed to take into account that the
memory palette has to be expanded to full RGB when it is written to PNG.

This is not likely to be a serious bug because the macro is new, the memory
format in question is likely to be rarely used and the result of an undersized
buffer fails in a safe way.

175a126a1a Simplified API: write-to-memory, overflow handling 
This implements an API and provides a number of assist macros to allow an
application which uses the simplified API write to bypass stdio and write
directly to memory.

It also includes some warnings (png.h) and some check code to detect *possible*
overflow in the ROW_STRIDE and simplified image SIZE macros.  This disallows
image width/height/format that *might* overflow.  A quiet API change that limits
in-memory image size (uncompressed) to less that 4GByte and image row size
(stride) to less than 2GByte.

18765d0032 Fix undefined behavior in pngvalid.c 
Undefined because (png_byte) << shift is undefined if it changes the signed bit
(because png_byte is promoted to int).  The libpng exported functions
png_get_uint_32 and png_get_uint_16 handle this.

Bug reported by David Drysdale as a result of reports from UBSAN in clang 3.8.

This changes pngvalid to use BE random numbers; this used to produce errors but
these should not be fixed as a result of the previous changes.
