The nvme spec defines the various fields that specify sizes for host
memory buffers in terms of 4096 chunks. So, rather than use a bare 4096
here, use NVME_HMB_UNITS. This is explicitly not the host page size of
4096, nor the default memory page size (mps) of the NVMe drive, but its
own thing and needs its own define.
No functional change is intended, only the logical spelling of 4k.

Targets like 'list-old-files' used "xargs -n1" to produce a list with
one file per line. Using xargs resulted in one fork+exec for each
Argument, resulting in rather long runtime. Instead, use sed to split
the list. On one machine `make list-old-files` took 30s wall clock time
with xargs and less than 1s with sed.

The RB_NEXT macro does not use its middle argument since commit
5fce408cc4 in 2004 (which ironically
fixed an "unused parameter" warning by introducing this warning in all
consumers). RB_PREV has also copied this unfortunate behavior of an
unused argument.
This results in 'parent' not being used. To workaround, inline the
value of 'parent' as the second argument to RB_NEXT.

For IO_APPEND VOP_WRITE()s, the code first does a
Getattr RPC to acquire the file's size, before it
can do the Write RPC.
Although NFS does not have an append write operation,
an NFSv4 compound can use a Verify operation to check
that the client's notion of the file's size is
correct, followed by the Write operation.
This patch modifies nfscl_wcc_data() to optionally
acquire the file's size, for use with an AppendWrite.
Although the "stuff" arguments are always NULL
(these were used for the Mac OSX port and should be
cleared out someday), make the argument to
nfscl_wcc_data() explicitly NULL for clarity.
This patch does not cause any semantics change until
the AppendWrite is added in a future commit.
