While we're scrubbing various btrees, cross-reference the records
with the other metadata.

Variable bit is being assigned a value that is never read, hence
the assignment is redundant and can be removed. Cleans up clang

Create some helper functions to check that a block pointer points
within the filesystem (or AG) and doesn't point at static metadata.
We will use this for scrub.

This is a purely mechanical patch that removes the private
__{u,}int{8,16,32,64}_t typedefs in favor of using the system
{u,}int{8,16,32,64}_t typedefs. This is the sed script used to perform
the transformation and fix the resulting whitespace and indentation
errors:
s/typedef\t__uint8_t/typedef __uint8_t\t/g
s/typedef\t__uint/typedef __uint/g
s/typedef\t__int\([0-9]*\)_t/typedef int\1_t\t/g

Add _query_range and _query_all functions to the realtime bitmap
allocator. These two functions are similar in usage to the btree
functions with the same name and will be used for getfsmap and scrub.

Al Viro noticed that xfs_lock_inodes should be static, and
that led to ... a few more.
These are just the easy ones, others require moving functions
higher in source files, so that's not done here to keep
this review simple.

The struct xfs_inode has two copies of the current timestamps in it,
one in the vfs inode and one in the struct xfs_icdinode. Now that we
no longer log the struct xfs_icdinode directly, we don't need to
keep the timestamps in this structure. instead we can copy them
straight out of the VFS inode when formatting the inode log item or
the on-disk inode.
This reduces the struct xfs_inode in size by 24 bytes.

Buffers without verifiers issue runtime warnings on XFS. We don't
have anything we can actually verify in the RT buffers (no CRCs, not
magic numbers, etc), but we still need verifiers to avoid the
warnings.
Add a set of dummy verifier operations for the realtime buffers and
apply them in the appropriate places.

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.

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.
