[PATCH 0/4] list-objects-filter cleanups

In the recent jk/plug-list-object-filter-leaks topic[1], I stopped short
of fixing all of the callers to actually initialize the filter struct
beyond zero-ing it.

This series does the cleanup that I was afraid to do there. :)

I think the end result is less confusing and error-prone. And as you can
see in patch 4, it matches how the code originally hoped to be written,
but the author was also afraid of the zero-initialization thing.

It is kind of churny, and carries some risk of regression (if I missed a
spot). IMHO it's worth it, but even if we don't take it, we should pick
up the first two patches, which are small bug-lets that the conversion
turned up.

These patches should be applied on top of jk/plug-list-object-filter-leaks,
which is currently in next.

  [1/4]: list-objects-filter: don't memset after releasing filter struct
  [2/4]: list-objects-filter: handle null default filter spec
  [3/4]: list-objects-filter: add and use initializers
  [4/4]: list-objects-filter: convert filter_spec to a strbuf
