[PATCH 0/5] pack-objects: better handling of negative options

This series fixes a few problems discussed on the security list, but I don't think the security implications are that interesting (an attacker would need to control config or command-line options, which are already pretty dangerous, and can mostly just cause the process to abort). But still worth addressing.

Patches 3 and 5 are the interesting ones. The rest are just cleaning up or improving test coverage.

  [1/5]: t5300: modernize basic tests
  [2/5]: t5300: check that we produced expected number of deltas
  [3/5]: pack-objects: clamp negative window size to 0
  [4/5]: t5316: check behavior of pack-objects --depth=0
  [5/5]: pack-objects: clamp negative depth to 0
