reftable: introduce `reftable_strdup()`
The reftable library provides the ability to swap out allocators. There is a gap here though, because we continue to use `xstrdup()` even in the case where all the other allocators have been swapped out. Introduce `reftable_strdup()` that uses `reftable_malloc()` to do the allocation. Signed-off-by: Patrick Steinhardt <ps@pks.im> Signed-off-by: Junio C Hamano <gitster@pobox.com>
