Log:
Do the first and mostly mechanical step of adding mutex support to the
bus_dma async callback scheme. Note that sparc64 does not seem to do
async callbacks. Note that ia64 callbacks might not be MPSAFE at the
moment. Note that powerpc doesn't seem to do async callbacks due to
the implementation being incomplete.
