When logging buffers, we attach a type to them that follows the
buffer all the way into the log and is used to identify the buffer
contents in log recovery. Both the realtime summary buffers and the
bitmap buffers do not have types defined or set, so when we try to
log them we see assert failure:
XFS: Assertion failed: (bip->bli_flags & XFS_BLI_STALE) || (xfs_blft_from_flags(&bip->__bli_format) > XFS_BLFT_UNKNOWN_BUF && xfs_blft_from_flags(&bip->__bli_format) < XFS_BLFT_MAX_BUF), file: fs/xfs/xfs_buf_item.c, line: 294
Fix this by adding buffer log format types for these buffers, and
add identification support into log recovery for them. Only build the log
recovery support if CONFIG_XFS_RT=y - we can't get into log recovery for real
time filesystems if support is not built into the kernel, and this avoids
potential build problems.

More on-disk format consolidation. A few declarations that weren't on-disk
format related move into better suitable spots.

More consolidatation for the on-disk format defintions. Note that the
XFS_IS_REALTIME_INODE moves to xfs_linux.h instead as it is not related
to the on disk format, but depends on a CONFIG_ option.

rbpp is always passed into xfs_rtmodify_summary
and xfs_rtget_summary, so there is no need to
test for it in xfs_rtmodify_summary_int.

xfs_rtmodify_summary and xfs_rtget_summary are almost identical;
fold them into xfs_rtmodify_summary_int(), with wrappers for each of
the original calls.
The _int function modifies if a delta is passed, and returns a
summary pointer if *sum is passed.

Move all the source files that are shared with userspace into
libxfs/. This is done as one big chunk simpy to get it done
quickly
