LOLLM points out that we pass the wrong btree cursor here. We want the
rtrefcount btree cursor, not the non-rt one. This is fairly benign
since it only affects tracing data.

This is the result of running the Coccinelle script from
scripts/coccinelle/api/kmalloc_objs.cocci. The script is designed to
avoid scalar types (which need careful case-by-case checking), and
instead replace kmalloc-family calls that allocate struct or union
object instances:
Single allocations: kmalloc(sizeof(TYPE), ...)
are replaced with: kmalloc_obj(TYPE, ...)
Array allocations: kmalloc_array(COUNT, sizeof(TYPE), ...)
are replaced with: kmalloc_objs(TYPE, COUNT, ...)
Flex array allocations: kmalloc(struct_size(PTR, FAM, COUNT), ...)
are replaced with: kmalloc_flex(*PTR, FAM, COUNT, ...)
(where TYPE may also be *VAR)
The resulting allocations no longer return "void *", instead returning
"TYPE *".

The xfs.h header conflicts with the public xfs.h in xfsprogs, leading
to a spurious difference in all shared libxfs files that have to
include libxfs_priv.h in userspace. Directly include xfs_platform.h so
that we can add a header of the same name to xfsprogs and remove this
major annoyance for the shared code.

If there's a gap between records in the rt refcount btree, we ought to
cross-reference the gap with the rtrmap records to make sure that there
aren't any overlapping records for a region that doesn't have any shared
ownership.

Add code to scrub realtime refcount btrees. Similar to the refcount
btree checking code for the data device, we walk the rmap btree for each
refcount record to confirm that the reference counts are correct.
