Ivan Shapovalov 627b530059 zdb: add --bin=(lsize|psize|asize) arg to control histogram binning
When counting blocks to generate block size histograms (`-bb`), accept a
`--bin=` argument to force placing blocks into all three bins based on
*this* size.

E.g. with `--bin=lsize`, a block with lsize=512K, psize=128K, asize=256K
will be placed into the "512K" bin in all three output columns. This
way, by looking at the "512K" row the user will be able to determine
how well was ZFS able to compress blocks of this logical size.

Conversely, with `--bin=psize`, by looking at the "128K" row the user
will be able to determine how much overhead was incurred for storage
of blocks of this physical size.
