fd8bba4b80 [libpng16] Changed NEON implementation selection mechanism to allow assembler
or intrinsics to be turned on during the build by defining
PNG_ARM_NEON_IMPLEMENTATION to the correct value (2 or 1).  The
default is "undefined" and the build type is selected in pngpriv.h.

db9d96840d [libpng16] Cleaned up ARM NEON compilation handling. The tests are now in
pngpriv.h and detect the broken GCC compilers.

83a841ab7c [libpng16] Fix compilation errors in filter_neon_intrinsics.c
Use filter_neon_intrinsics.c in preference to filter_neon.S when possible.

18dd07e3e6 [libpng16] Removed PNG_FILTER_OPTIMIZATIONS and PNG_ARM_NEON_SUPPORTED from
pnglibconf.h, allowing more of the decisions to be made internally
(pngpriv.h) during the compile.  Without this, symbol prefixing is broken
under certain circumstances on ARM platforms.  Now only the API parts of
the optimizations ('check' vs 'api') are exposed in the public header files
except that the new setting PNG_ARM_NEON_OPT documents how libpng makes the
decision about whether or not to use the optimizations.

09a5ca72ac [libpng16] Allow run-time ARM NEON checking to be disabled. A new configure
option:
    --enable-arm-neon=always will stop the run-time checks. New checks
    within arm/arm_init.c will cause the code not to be compiled unless
    __ARM_NEON__ is set. This should make it fail safe (if someone asks
    for it on then the build will fail if it can't be done.)
Fixed ALIGNED_MEMORY support.

9d2e875826 [libpng16] Made symbol prefixing work with the ARM neon optimizations. Also allow pngpriv.h
to be included for preprocessor definitions only, so it can be used in non-C/C++
files. Back ported from libpng 1.7.

6cf32b460f [libpng16] Rearranged the ARM-NEON optimizations: Isolated the machine specific
code to the hardware subdirectory and added comments to pngrutil.c so that
implementors of other optimizations know what to do.
