interfaces: Stop exposing wallet destdata to gui

Browse Source 
Stop giving GUI access to destdata rows in database. Replace with narrow
API just for saving and reading receive request information.

This simplifies code and should prevent the GUI from interfering with
other destdata like address-used status.

Note: No user-visible behavior is changing in this commit. New
CWallet::SetAddressReceiveRequest() implementation avoids a bug in
CWallet::AddDestData() where a modification would leave the previous
value in memory while writing the new value to disk. But it doesn't
matter because the GUI doesn't currently expose the ability to modify
receive requests, only to add and erase them.
