[PATCH v2 0/7] hn/reftable "fixes" for BSD

A few issues I noticed while buiding "seen" in some BSD systems.

Patches 1-3 aren't changed from v1, and 4 had the fixes suggested by Junio[1] added.

Patch 5 affects an EOL NetBSD 7.2 system and therefore might be dropped but I thought it was safe/generic enough and might become useful in other old systems as well.

The last 2 patches are a well known recurring issue, that even prompted a explicit documentation update in cc0c42975a (CodingGuidelines: spell out post-C89 rules, 2019-07-16).

All these patches are expected to be applied on top of hn/reftable and hopefully absorved and discarded.

Carlo Marcelo Arenas Belón (7):
  fixup! Provide zlib's uncompress2 from compat/zlib-compat.c
  reftable: clarify zlib version dependency
  openbsd: allow reftable building with zlib 1.2.3
  fixup! reftable: add dump utility
  fixup! Provide zlib's uncompress2 from compat/zlib-compat.c
  fixup! reftable: reftable file level tests
  fixup! reftable: (de)serialization for the polymorphic record type
