Give the "malloc" backing of md(4) an adaptive multilevel index tree to
remove the need for a contiguous array with pointers to all the sectors.

Try to make failure to malloc(9) memory a non-hang situation.

Eventually this will allow us to test the 64bit cleanness of the disk
I/O patch, but more work is outstanding here and elsewhere.
