[libpng15] Merged pngvalid and pngtest from libpng-1.5; made compressed chunks
...
after IDAT work with the progressive read code (this is a minor and
somewhat ugly fix-up; the proper fix is in 1.6).

[libpng16] Choose to use windowBits==15 or the zlib header setting via the
...
benign-errors setting. If benign errors are allowed, then ignore
the windowBits setting in the zlib header.
Zlib-1.2.8 and earlier don't allow us to decrease the windowBits, so
undid the improvement in beta04.

is split out entirely to the arm subdirectory and changes to configure.ac and
Makefile.am to add new stuff are reduced. Now material code changes,
although for build test purposes, --enable-arm-neon now builds on non-ARM
systems.
Rebuilt Makefile.in, configure, etc., with autoconf-2.69 and automake-1.2.5.

[libpng15] Fixed bug in pngvalid on early allocation failure; fixed type cast
...
in pngmem.c; pngvalid would attempt to call png_error() if the allocation
of a png_struct or png_info failed. This would probably have led to a
crash. The pngmem.c implementation of png_malloc() included a cast
to png_size_t which would fail on large allocations on 16-bit systems.

[libpng15] Fixed compiler warnings with Intel and MSYS compilers.
...
The logical shift fix for Microsoft Visual C is required by other compilers,
so this enables that fix for all compilers when using compile-time constants.
Under MSYS 'byte' is a name declared in a system header file, so we
changed the name of a local variable to avoid the warnings that result.
