Due to the iterative process of selecting new coins in each loop a new fee is
calculated that needs to be met each time. In the typical case if the most
recent iteration of the loop produced a much smaller transaction and we have now
gathered inputs with too many fees, we can just reduce the change. However in
the case where there is no change output, it is possible to end up with a
transaction which drastically overpays fees. This commit addresses that case,
by creating a change output if the overpayment is large enough to support it,
this is accomplished by rerunning the transaction creation loop without
selecting new coins.
Thanks to instagibbs for working on this as well
475c08c Add PR description to merge commit in github-merge.py (Pieter Wuille)
Pull request description:
There is often some context given in PR descriptions that is missing from commits, and it may be worthwhile to retain that information in our history in git. This PR adds that information to the merge commit when created through `github-merge.py`.
We should also encourage people to provide as much information as possible in the PR commits themselves, but I believe that is an orthogonal issue. Individual commits don't need to have a description of the overall goal of a PR.

That OP_NOP10 is the last executable opcode is a bit of a obscure trivia, and the MAX_OPCODE constant already exists. This merely standardizes use of MAX_OPCODE over OP_NOP10 where it makes sense and is more clear.

Add support for setting each of these attributes on a per RPC call basis to sendtoaddress, sendmany, fundrawtransaction (already had RBF), and bumpfee (already had RBF and conf target).
Note that the CScheduler thread cant be running at this point,
it has already been stopped with the rest of the init threadgroup.
Thus, just calling any remaining loose callbacks during Shutdown()
is sane.
This will be used by CValidationInterface soon.
This requires a bit of work as we need to ensure that most of our
callbacks happen in-order (to avoid synchronization issues in
wallet) - we keep our own internal queue and push things onto it,
scheduling a queue-draining function immediately upon new
callbacks.

GetMinimumFee now passes the conservative argument into estimateSmartFee.
Call CalculateEstimateType(mode) before calling GetMinimumFee or estimateSmartFee to determine the value of this argument.
CCoinControl can now be used to control this mode.
