btrfs-progs: support for different csum algorithims

This is the btrfs-progs version of the patch to add the ability to have
different csum algorithims.  Note I didn't change the image maker since it
seemed a bit more complicated than just changing some stuff around so I will let
Yan take care of that.

Everything else was converted and for now a mkfs just
sets the type to be BTRFS_CSUM_TYPE_CRC32.
