Patch 04/33 in David Turner's refs-backend-lmdb series v7 [1] did way
too much in a single patch, and in fact got a few minor things wrong.
Instead of that patch, I suggest this patch series, which

* Splits the changes into smaller steps.

* Adds a bunch of tests of deleting references with invalid but safe
  names, including symbolic references and including references
  reached via symbolic references. Two of these tests fail when run
  against David's patch 04 due to changes in output.

* Arranges for the "flags" argument to read_raw_ref() always to be
  non-NULL, which eliminates the need for a lot of "if (flags)"
  guards.

* Eliminates the now-superfluous "bad_name" local variable.

* Move the management of the scratch space sb_path from
  resolve_ref_unsafe() to read_raw_ref().

* Inlines resolve_ref_1() into resolve_ref_unsafe().

* Changes some callers of resolve_ref_unsafe() to pass flags=NULL
  instead of creating a local flags variable that is never used.

* Changes some callers to check for errors before using the return
  value of resolve_ref_unsafe().

I hope that the result is easier to understand and audit, even though
it consists of more patches (indeed, *because* of that).

This patch series applies on top of David's patch 03/33 the same place
David applied it in his repo [2]. It is also available in situ from my
GitHub repo [3] as branch "pluggable-backends-patch4"

If this series is used, later patches from David's series would need
to be rebased on top of it. This is a little bit messy but not
difficult; the result can be seen in branch
"pluggable-backends-rebased" in my GitHub repo [3] (albeit without
adjusting the LMDB-related patches).
