btrfs-progs: Introduce sectorsize nodesize and stripesize members for 

btrfs_fs_info

Just like what we do in kernel, since we will not support different
leaf/node/stripe size per tree, there is no need to store these block
sizes in btrfs_root.

This patch will introduce these block size members into btrfs_fs_info
structure, allowing us to convert such usage in later patches.
