Ok...corrected a problem with new block allocation in nids, and it no longer

goes into an infinite loop while doing certain kinds of read.  Also, it zeros
out new blocks to make things easier to cope with in the hex editor, it'll
probably also compress better.

I also fixed Bu::MemBuf so that you can now write to arbitrary places
mid-stream.
