The boundary test for the fixed-offset parts of xfs_attr_sf_entry in
xfs_attr_shortform_verify is off by one, because the variable array
at the end is defined as nameval[1] not nameval[].
Hence we need to subtract 1 from the calculation.
This can be shown by:
# touch file
# setfattr -n root.a file
and verifications will fail when it's written to disk.
This only matters for a last attribute which has a single-byte name
and no value, otherwise the combination of namelen & valuelen will
push endp further out and this test won't fail.

The inode chunk allocation transaction reserves inobt_maxlevels-1
blocks to accommodate a full split of the inode btree. A full split
requires an allocation for every existing level and a new root
block, which means inobt_maxlevels is the worst case block
requirement for a transaction that inserts to the inobt. This can
lead to a transaction block reservation overrun when tmpfile
creation allocates an inode chunk and expands the inobt to its
maximum depth. This problem has been observed in conjunction with
overlayfs, which makes frequent use of tmpfiles internally.
The existing reservation code goes back as far as the Linux git repo
history (v2.6.12). It was likely never observed as a problem because
the traditional file/directory creation transactions also include
worst case block reservation for directory modifications, which most
likely is able to make up for a single block deficiency in the inode
allocation portion of the calculation. tmpfile support is relatively
more recent (v3.15), less heavily used, and only includes the inode
allocation block reservation as tmpfiles aren't linked into the
directory tree on creation.
Fix up the inode alloc block reservation macro and a couple of the
block allocator minleft parameters that enforce an allocation to
leave enough free blocks in the AG for a full inobt split.

A transaction roll is not necessary immediately after setting the
INCOMPLETE flag when removing a node xattr entry with remote value
blocks. The remote block invalidation that immediately follows setting
the flag is an in-core only change. The next step after that is to start
unmapping the remote blocks from the attr fork, but the xattr remove
transaction reservation includes reservation for full tree splits of the
dabtree and bmap tree. The remote block unmap code will roll the
transaction as extents are unmapped and freed.

To help pre-simplify xfs_attr_set_args, we need to hoist transaction
handling up, while modularizing the adjacent code down into helpers. In
this patch, hoist the commit in xfs_attr_try_sf_addname up into the
calling function, and also pull the attr list creation down.

Split out new helper function xfs_attr_leaf_try_add from
xfs_attr_leaf_addname. Because new delayed attribute routines cannot
roll transactions, we split off the parts of xfs_attr_leaf_addname that
we can use, and move the commit into the calling function.

Since delayed operations cannot roll transactions, pull up the

Break xfs_attr_rmtval_set into two helper functions
xfs_attr_rmt_find_hole and xfs_attr_rmtval_set_value.
xfs_attr_rmtval_set rolls the transaction between the helpers, but
delayed operations cannot. We will use the helpers later when
constructing new delayed attribute routines.

Delayed operations cannot return error codes. So we must check for
these conditions first before starting set or remove operations
