Unit tests for [drains], [poison] and [slow], with apply_to=opponent
Here `apply_to=opponent` means that the weapon special gives the opponent the ability, the unit that should get poisoned or slowed is the unit that has the weapon special. There's a known bug in 1.16, that `apply_to=opponent` check the wrong unit to see it it's `unpoisonable`, `undrainable` etc. It also checks the wrong unit to see if it's already poisoned or slowed, so a battle between two units that both have reverse-poison results in at most one being poisoned. As 1.16 has already been released, to avoid OOS the test is checking that the current behavior's known bug is preserved. For the 1.17 branch, the five lines labelled `preserving known bug` will be changed to test the reverse. Most of the credit for this is Newfrenchy's, as he's already written a fix and a WML based test. This commit uses a Lua test instead to test more combinations of statuses. This adds a `COMMON_KEEP_A_B_UNIT_TEST` macro, which is a counterpart to the `GENERIC_UNIT_TEST` macro that starts the leaders next to each other, ready to attack. The `A_B` is because I'm planning a multiple-side variant too, and the main reason for using separate files is Git's fuzzy-patch matching when merging and rebasing. Having large blocks of identical text in `wml_unit_test_macros.cfg` can mean the wrong section gets patched. There's no test for [petrify], as simulate_combat doesn't provide a stat for it. This tests only 3 of the 6 abilities whose behavior will change in 1.17's equivalent of 1.16's7b39b65606. That's sufficient to prevent any accidental copy of the 1.17 fix to 1.16, and my thoughts on testing the others are: * [firststrike]'s test is in7b39b65606. It crashed, so is fixed in 1.16. * [drains], [poison] and [slow] are tested here. * [petrify] ends combat, it's also not exposed in simulate_combat's stats. * [plague] triggers after combat ends.
