Would you ever want to insert a value in between any of these? Or do the
values of these ordinals have no meaning?

Is this comment right? MUST_PASS_ALL seems 'most restrictive', not 'least
restrictive'.

bq. Summary
bq. -------
bq.
bq. FilterList.filterKeyValue does not always return the most optimal
ReturnCode in both the AND and OR conditions.
bq.
bq. For example, if you have F1 AND F2, F1 returns SKIP. It immediately
returns the SKIP. However, if F2 would have returned NEXT_COL or NEXT_ROW or
SEEK_NEXT_USING_HINT, we would actually be able to return the more optimal
ReturnCode from F2.
bq.
bq. For AND conditions, we can always pick the most restrictive return code.
bq.
bq. For OR conditions, we must always pick the least restrictive return code.
bq.
bq. This JIRA is to review the FilterList.filterKeyValue() method to try and
make it more optimal and to add a new unit test which verifies the correct
behavior.

bq. This addresses bug HBASE-4410.
