Comment (by teor):

 Please see my branch `bug16069-exit-policy-inconsistent-v3`.

 It fixes the issues identified above, and also correctly ignores just a
 single policy line on `accept6/reject6 IPv4:...` (before, it ignored the
 entire policy). I added a new flag `is_ignored` to `addr_policy_t` to skip
 a single policy, and updated the unit tests for it.

 Commits in this branch are:
     * Fix comments that are incomplete or incorrect
     * Add warnings / notices and ignore accept6/reject6 IPv4 (with unit
 test)
     * Add a warning for redundant ExitPolicy lines after accept/reject *:*
 and variants
     * Make accept6/reject6 produce IPv6 wildcards only (with unit test)
