Wire up realtime refcount btree cursors wherever they're needed
throughout the code base.

Plumb in the pieces we need to embed the root of the realtime refcount
btree in an inode's data fork, complete with new fork type and
on-disk interpretation functions.

Reserve some free blocks so that we will always have enough free blocks
in the data volume to handle expansion of the realtime refcount btree.

Add a metadir path to select the realtime refcount btree inode and load
it at mount time. The rtrefcountbt inode will have a unique extent format
code, which means that we also have to update the inode validation and
flush routines to look for it.

Now that we have reflink on the realtime device, refcount intent items
have to support remapping extents on the realtime volume.

Extend the refcount update (CUI) log items with a new realtime flag that
indicates that the updates apply against the realtime refcountbt. We'll
wire up the actual refcount code later.

Prepare the high-level refcount functions to deal with the new realtime
refcountbt and its slightly different conventions. Provide the ability
to talk to either refcountbt or rtrefcountbt formats from the same high
level code.
Note that we leave the _recover_cow_leftovers functions for a separate
patch so that we can convert it all at once.

Implement the generic btree operations needed to manipulate rtrefcount
btree blocks. This is different from the regular refcountbt in that we
allocate space from the filesystem at large, and are neither constrained
to the free space nor any particular AG.

Make sure that there's enough log reservation to handle mapping
and unmapping realtime extents. We have to reserve enough space
to handle a split in the rtrefcountbt to add the record and a second
split in the regular refcountbt to record the rtrefcountbt split.

Start filling out the rtrefcount btree implementation. Start with the
on-disk btree format; add everything needed to read, write and
manipulate refcount btree blocks. This prepares the way for connecting
the btree operations implementation.

Add new realtime refcount btree definitions. The realtime refcount btree
will be rooted from a hidden inode, but has its own shape and therefore
needs to have most of its own separate types.

Change the startblock and blockcount fields of xfs_refcount_irec to be
64 bits wide. This enables us to use the same high level refcount code
for either tree. We'll also collect all the resulting breakage fixes
here.

In preparation for widening the refcount code to accept 64-bit extents,
clean up the method signature for xfs_reflink_find_shared by passing in
the bmbt irec that both callers are checking, and pass back out the same
types that are found in the irec. Make the function static since there
are fewer callers than there used to be.

Prepare the rest of refcount btree tracepoints for use with realtime
reflink by making them take the btree cursor object as a parameter.
This will save us a lot of trouble later on.
Remove the xfs_refcount_recover_extent tracepoint since it's already
covered by other refcount tracepoints.

The only user of the "ag" tracepoint event classes is the refcount
btree, so rename them to make that obvious and make them take the btree
cursor to simplify the arguments. This will save us a lot of trouble
later on.

Create a new noalloc state for the per-AG structure that will disable
block allocation in this AG. We accomplish this by subtracting from
fdblocks all the free blocks in this AG, hiding those blocks from the
allocator, and preventing freed blocks from updating fdblocks until
we're ready to lift noalloc mode.
Note that we reduce the free block count of the filesystem so that we
can prevent transactions from entering the allocator looking for "free"
space that we've turned off incore.

Fix a couple of minor mistakes in the scrub tracepoints that can
manifest when inode-rooted btrees are enabled. The existing code worked
fine for bmap btrees, but we should tighten the code up to be less

The order of the functions in this file has gotten a little confusing
over the years. Specifically, the two data device implementations
(bnobt and rmapbt) could be adjacent in the source code instead of split
in two by the logdev and rtdev fsmap implementations. We're about to
add more functionality to this file, so rearrange things now.

Variable names in this code module are inconsistent and confusing.
xfs_map_extent describe file mappings, so rename them "map".
xfs_rmap_intents describe block mapping intents, so rename them "ri".

The size of filesystem transaction reservations depends on the maximum
height (maxlevels) of the realtime btrees. Since we don't want a grow
operation to increase the reservation size enough that we'll fail the
minimum log size checks on the next mount, constrain growfs operations
if they would cause an increase in those maxlevels.

When rmap is enabled, XFS expects a certain order of operations, which
is: 1) remove the file mapping, 2) remove the reverse mapping, and then
3) free the blocks. xfs_bmap_del_extent_real tries to do 1 and 3 in the
same transaction, which means that when rtrmap is enabled, we have to
use realtime EFIs to maintain the expected order.
