Replace "is called with" wording that doesn't apply to deduction guides. Move rules about qualifying as input iterators or allocators to [container.requirements.general].

While we are in the vicinity, basic_string's deduction guide specification is missing a \pnum.

The missing \pnum is fixed.

Hmm, does has a template parameter named \tcode{InputIterator} sound better?

I don't like this note as-written: it suggests that implementations can impose unbounded constraints on the types in questions, rather than merely constraints that are derivable from the allocator or input iterator requirements.
I'm inclined to merge this without the new note.
