CALLOUT_MPSAFE has lost its meaning since r141428, i.e., for more than ten
years for head. However, it is continuously misused as the mpsafe argument
for callout_init(9). Deprecate the flag and clean up callout_init() calls
to make them more consistent.

MFHead @ r275232

After some horrible wrestling with Subversion's worthless merge
implementation, merge ^/head r275078 through r275117.

Note that all the extraneous mergeinfo is there because Subversion
created it.

After some horrible wrestling with Subversion's worthless merge
implementation, merge ^/head r275078 through r275117.

Note that all the extraneous mergeinfo is there because Subversion
created it. I'll hopefully be able to remove it again when merging back
to head.

Fix various bugs with freeing static DMA allocations in sound drivers:
- Don't compare the DMA map to NULL to determine if bus_dmamap_unload()
should be called when releasing a static allocation.

Fix various bugs with freeing static DMA allocations in sound drivers:
- Don't compare the DMA map to NULL to determine if bus_dmamap_unload()
should be called when releasing a static allocation. Instead, compare
the bus address against 0.
- Don't assume that the DMA map for static allocations is NULL. Instead,
save the value set by bus_dmamem_alloc() so it can later be passed to
bus_dmamem_free(). Also, add missing calls to bus_dmamap_unload() in
these cases before freeing the buffer.
- Use the bus address from the bus_dma callback instead of calling
vtophys() on the address allocated by bus_dmamem_alloc().
