Re: [PATCH v4 20/21] refs: add LMDB refs storage backend

Add a database backend for refs using LMDB.  This backend runs git
for-each-ref about 30% faster than the files backend with fully-packed
refs on a repo with ~120k refs.  It's also about 4x faster than using
fully-unpacked refs.  In addition, and perhaps more importantly, it
avoids case-conflict issues on OS X.

When I compile this using gcc with -Werror=pointer-arith, I get the
following errors:

refs/lmdb-backend.c: In function ‘rename_reflog_ent’:
refs/lmdb-backend.c:1068:39: error: pointer of type ‘void *’ used in arithmetic [-Werror=pointer-arith]
  strbuf_add(&new_key_buf, key.mv_data + key.mv_size - 8, 8);
                                       ^
