xfs_rtalloc.c is partially shared with userspace. Split the file up
into two parts - one that is kernel private and the other which is
wholly shared with userspace.

There are quite a few realtime device definitions shared with
userspace. Move them from xfs_rtalloc.h to xfs_rt_alloc_defs.h
so we don't need to share xfs_rtalloc.h with userspace anymore.

Recent testers were slightly confused that a realtime mount failed
due to missing CONFIG_XFS_RT; we can make that a little more
obvious.
V2: drop the else as suggested by Christoph

When mount fails after allocating the real-time inodes we currently leak
them. Add a new helper to free the real-time inodes which can be used by
both the mount and unmount path.

Use XFS_IS_REALTIME_INODE in more places, and #define it to 0 if
CONFIG_XFS_RT is off. This should be safe because mount checks in
xfs_rtmount_init:
so if we get mounted w/o CONFIG_XFS_RT, no realtime inodes should be
encountered after that.
Defining XFS_IS_REALTIME_INODE to 0 saves a bit of stack space,
presumeably gcc can optimize around the various "if (0)" type checks:
xfs_alloc_file_space -8 xfs_bmap_adjacent -16 xfs_bmapi -8
xfs_bmap_rtalloc -16 xfs_bunmapi -28 xfs_free_file_space -64 xfs_imap +8
<-- ? hmm. xfs_iomap_write_direct -12 xfs_qm_dqusage_adjust -4
xfs_qm_vop_chown_reserve -4

Initial git repository build. I'm not bothering with the full history,
even though we have it. We can create a separate "historical" git
archive of that later if we want to, and in the meantime it's about
3.2GB when imported into git - space that would just make the early
git days unnecessarily complicated, when we don't have a lot of good
infrastructure for it.
Let it rip!
