db: add invoicerequests table.

We no longer use offers for "I want to send you money", but we'll use
invoice_requests directly.  Create a new table for them, and
associated functions.

The "localofferid" for "pay" and "sendpay" is now "localinvreqid".
This is an experimental-only option, so document the change under
experimental only.
