[iptables PATCH 0/3] Extend xlate-test to replay results

[Phil Sutter <phil@nwl.cc>]

If nftables has libxtables support, it will utilize the .xlate callbacks
to print compat expressions in native nftables syntax. Users may miss
the fact that what they're seeing is not the reality and assume they may
manipulate (including store and reload) the ruleset using nftables. This
wasn't a big deal if iptables-nft understood all the translations
libxtables offers.

To start catching up on this, add an optional replay mode to
xlate-test.py checking if what was translated is correctly parsed back
into the original input (or at least a semantical equivalent).

Patches 1 and 2 are prep work, patch 3 has the gory details.

Phil Sutter (3):
  tests: xlate-test: Cleanup file reading loop
  tests: xlate-test.py: Introduce run_proc()
  tests: xlate-test: Replay results for reverse direction testing
