Paul Dagnelie a981cb69e4 Implement dynamic gang header sizes 
ZFS gang block headers are currently fixed at 512 bytes. This is
increasingly wasteful in the era of larger disk sector sizes. This PR
allows any size allocation to work as a gang header. It also contains
supporting changes to ZDB to make gang headers easier to work with.
