Added POWERPC-VSX support.
Report whether using optimizations, when operating verbosely.
Added filter_method 6 (same as filter 5 with -speed).
Added "methods" 149-176 (that use filter_method 6).
Only issue a warning when the "build" and "runtime" libpng versions
differ in the first 4 symbols, indicating incompatible versions.
