[mythtv] [mythtv-users] Would a capture card by any other name still record as sweet?

The actual use of multiple inputs on the same card has already been
pretty rare, even more so today.  We can get rid of a lot of
complication for everyone (the card/input model) at the expense of a
little more complication for a small number of people (those who
actually use multiple inputs).

The scheduler already has to deal with two types of relationships
between inputs.  Inputs on the same card and inputs in the same input
group.  The multirec without virtual tuners feature will add yet
another -- can an input be shared with itself.  Since input groups can
also cover the inputs on the same card case, we don't need the latter.
The scheduler then still only needs to know about 2 types of
relationships instead of 3.
