Simplify the bitmap walker subroutines. This change... * Separates walking from sweeping. Walking had been implemented by a sweeping with an empty mark bitmap argument. * Localizes the finger machinations to scanBitmapCallback. There is one use of the finger but all callbacks received the argument. * Inlines a simplified bitmap walking routine operating a pointer at a time. Only sweeping benefits from batching decoded addresses.
