[libpng15] Rearranged building of ARM NEON optimizations. The ARM specific code

Browse Source 
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.
