[PATCH 07/16] btrfs: move BTRFS_FS_STATE* defs and helpers to fs.h

[Josef Bacik <josef@toxicpanda.com>]

We're going to use fs.h to hold fs wide related helpers and definitions,
move the FS_STATE enum and related helpers to fs.h, and then update all
files that need these definitions to include fs.h.
