Merge r266746, 266775:
Now that there are separate back-end implementations of busdma, the bounce
implementation shouldn't steal flags from the common front-end.
Move those flags to the back-end.
Eliminate the fake contig_dmamap and replace it with a new flag,
BUS_DMA_KMEM_ALLOC. They serve the same purpose, but using the flag
means that the map can be NULL again, which in turn enables significant
optimizations for the common case of no bouncing.
