CTxDestination is really our internal representation of an address and
doesn't really have anything to do with standard script types, so move
them to their own file.
In order to get records beginning with a prefix, we will need a cursor
specifically for that prefix. So add a GetPrefixCursor function and
DatabaseCursor classes for dealing with those prefixes.
Tested on each supported db engine.
1) Write two different key->value elements to db.
2) Create a new prefix cursor and walk-through every returned element,
verifying that it gets parsed properly.
3) Try to move the cursor outside the filtered range: expect failure
and flag complete=true.

The wallet tests and benchmarks both had helper functions for loading
and unloading the wallet for the test that were almost identical.
These functions are consolidated and reused.
MockableDatabase is a WalletDatabase that allows us to interact with the
records to change them independently from the wallet, as well as
changing the return values from within the tests. This will give us
greater flexibility in testing the wallet.
files share the same purpose, and we shouldn't have wallet code
inside the test directory.
This later is needed to use wallet util functions in the bench
and test binaries without be forced to duplicate them.
No change in behavior. This just moves some code from the ListCoins test
setup to a reusable util function, so it can be reused in a new test in
the next commit.
