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.

c3e7e7d715 [libpng16] tests backported from libpng 1.7 
This updates libpng16 with all the test changes from libpng17,
including changes to pngvalid.c to ensure that the original,
distributed, version of contrib/visupng/cexcept.h can be used.

pngvalid contains the correction to the use of SAVE/STORE_
UNKNOWN_CHUNKS; a bug revealed by changes in libpng 1.7.  More
tests contain the --strict option to detect warnings and the
pngvalid-standard test has been corrected so that it does not
turn on progresive-read (there is a separate test which does
that.)

Some signed/unsigned fixes have been made.

61ea3eacb0 [libpng16] Reverted use png_get_libpng_ver(NULL) instead of PNG_LIBPNG_VER_STRING 
in the manual, example.c, pngtest.c, and applications in the contrib directory.
It was incorrect advice.

03df189954 [libpng16] Fixed array size calculations to avoid warnings. At various points 
in the code the number of elements in an array is calculated using
sizeof.  This generates a compile time constant of type (size_t) which
is then typically assigned to an (unsigned int) or (int). Some versions
of GCC on 64-bit systems warn about the apparent narrowing, even though
the same compiler does apparently generate the correct, in-range,
numeric constant.  This adds appropriate, safe, casts to make the
warnings go away.

6f2c50e7fc [libpng16] Free all allocated memory in pngimage. The file buffer cache was left 
allocated at the end of the program, harmless but it causes memory

John Bowler
dba54b8888 [libpng16] Moved OS dependent code from arm/arm_init.c, to allow the included 
implementation of the ARM NEON discovery function to be set at
build-time and provide sample implementations from the current code in the
contrib/arm-neon subdirectory. The __linux__ code has also been changed to
compile and link on Android by using /proc/cpuinfo, and the old linux code
is in contrib/arm-neon/linux-auxv.c.  The new code avoids POSIX and Linux
dependencies apart from opening /proc/cpuinfo and is C90 compliant.
