yongdev c9e36046a3 libswscale: use unaligned read/write macros in planarCopyWrapper ...

When performing unscaled planar copies or format conversions on 16-bit
buffers in planarCopyWrapper, srcPtr2 and dstPtr2 are not guaranteed to
be 8-byte aligned (e.g. subsampled chroma planes with non-multiple-of-8
widths/strides or odd slice offsets).

AV_RN64A / AV_WN64A and AV_RN32A / AV_WN32A cast pointers to av_alias64
or av_alias32 which have __attribute__((aligned(8))) or aligned(4).
Dereferencing unaligned pointers with aligned attribute triggers Undefined
Behavior traps (SIGILL / UD1 instruction with Clang -fsanitize=alignment).
Replace them with AV_RN64 / AV_WN64 and AV_RN32 / AV_WN32.
