Don't overpay fee if we have selected new coins that result in a smaller transaction.
...
On repeated calls to SelectCoins we try to meet the fee necessary for the last transaction, the new fee required might be smaller, so increase our change by the difference if we can.

Try to reduce change output to make needed fee in CreateTransaction
...
Once we've picked coins and dummy-signed the transaction to calculate fee, if we don't have sufficient fee, then try to meet the fee by reducing change before resorting to picking new coins.

Wallet: Do not perform ECDSA in the fee calculation inner loop.
...
Performing signing in the inner loop has terrible performance
when many passes through are needed to complete the selection.
Signing before the algorithm is complete also gets in the way
of correctly setting the fee (e.g. preventing over-payment when
the fee required goes down on the final selection.)
Use of the dummy might overpay on the signatures by a couple bytes
in uncommon cases where the signatures' DER encoding is smaller
than the dummy: Who cares?

Remove member variable hadNoDependencies from CTxMemPoolEntry
...
Fee estimation can just check its own mapMemPoolTxs to determine the same information. Note that now fee estimation for block processing must happen before those transactions are removed, but this shoudl be a speedup.

Make RelayWalletTransaction attempt to AcceptToMemoryPool.
...
This resolves an issue where a wallet transaction which failed to
relay previously because it couldn't make it into the mempool
will not try again until restart, even though mempool conditions
may have changed.
Abandoned and known-conflicted transactions are skipped.
Some concern was expressed that there may be users with many
unknown conflicts would waste a lot of CPU time trying to
add them to their memory pools over and over again. But I am
doubtful these users exist in any number, if they do exist
they have worse problems, and they can mitigate any performance
issue this might have by abandoning the transactions in question.
