Revert "Revert "Revert "guard old apis for querying byte-size of a bitmap/imageinfo/pixmap"""

This reverts commit cd284c532376d16fcc4ed75baf3da65c3e4a2e95.

Reason for revert:

assert fired in SkMallocPixelRef.cpp:61: fatal error: "assert(info.computeByteSize(rowBytes) == info.getSafeSize(rowBytes))"

google3 thinks it was from surface_rowbytes
