  - Fix deadlock when adding keys from SKS recon.
* debian/mkdists:
  - Packaging script should fail on error.
* openpgp/recon.go:
  - Add previously missing elements to prefix tree.
* hkp/requests.go, openpgp/add.go, openpgp/io.go, openpgp/recon.go,
  openpgp/responses.go, openpgp/schema.go, openpgp/types.go,
  openpgp/worker.go:
  - Add fallback to track unsupported keys discovered through
    gossip. LP: #1208290
  - Initialize current digests in KeyChange for defined behavior in
    change consumers.
* cmd/hockeypuck-load/main.go, openpgp/recon.go:
  - Log public key digest when loading.
  - Removed key reversal to match latest conflux Zp byte ordering fix.
* cmd/hockeypuck-load/main.go, hkp/requests.go, openpgp/add.go,
  openpgp/recon.go, openpgp/worker.go:
  - Fix off-by-one in drop, take flags of hockeypuck-load. Fix i386
    compile issue with max int.
  - Workaround some concurrency issues between adding keys, recon recovery,
    and incoming queries.
* openpgp/add.go, openpgp/recon.go, openpgp/worker.go:
  - Fix goroutine leak from early exit while enumerating keys.
  - Multiplex peer recovery to goroutines aggregating recovery requests,
    one per peer.

* openpgp/validate.go:
  - Add hockeypuck.openpgp.strict option to reject key material containing
    *anything* we can't parse. Useful for peering with SKS, as we can
    track recovered unsupported keys for future reloading. LP: #1208290
