b4a08b81b2 [libpng15] Ensure that NEON filter stuff is completely disabled when 
switched 'off'.  Previously the ARM NEON specific files were still built
if the option was switched 'off' as opposed to being explicitly disabled.

c34143f615 [libpng15] Corrected Android builds and corrected libpng.vers with symbol 
prefixing This adds an API to set optimization options externally,
    providing an alternative and general solution for the non-portable
    run-time tests used by the ARM Neon code.  It also makes those tests
    compile and link on Android.
  The order of settings vs options in pnglibconf.h is reversed to allow
    settings to depend on options and options can now set (or override) the
    defaults for settings.

da3031a7d9 [libpng15] Use approved/supported Android method to check for NEON, use Linux/POSIX 
1003.1 API to check /proc/self/auxv avoiding buffer allocation and other
library calls.

62cfc893e0 [libpng15] Rearranged building of ARM NEON optimizations. The ARM specific code 
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.
