xfarray: don't allow users to unset in the middle of an array

Now that we've merged online repair and removed some clunky parts of the
original online checking code, the only user of xfarray_unset is the
free space btree repair code, and it only needs to be able to remove
records from the end of the array.  Let's remove all the code that
handles "unset" array elements that are not at the end, because we can
just reduce the array element count.

Remove the "store anywhere" function because it was only ever used by
the callers who used unset to remove elements in the middle of the
array.
