More accurate than simply adding one byte per input, and properly handles the
case where the original transaction happened to have very small signatures

5b15870 Use incrementalRelayFee for BIP 125 replacement (Alex Morcos)
The result value indicates the actual fee on the transaction that was replaced. But there is an error message which uses the description 'oldfee' to refer to the original fee rate applied to the new transaction's estimated max size. It was confusing that two different uses of 'oldfee' had two different numeric values.
Have wallet's default bump value be higher than the default incrementalRelayFee to future proof against changes to incremental relay fee. Only applies when not setting the fee rate directly.
Use the wallet's fee calculation logic to properly clamp fee against minimums and maximums when calculating the fee for a bumpfee transaction. Unless totalFee is explictly given, in which case, manually check against min, but do nothing to adjust given fee.
In all cases do a final check against maxTxFee (after adding any incremental amount).

9aa4e6a [Wallet] Add an option to keep the change address key, true by default (Jonas Schnelli)
This command allows a user to increase the fee on a wallet transaction T, creating a "bumper" transaction B.
T must signal that it is BIP-125 replaceable.
T's change output is decremented to pay the additional fee. (B will not add inputs to T.)
T cannot have any descendant transactions.
Once B bumps T, neither T nor B's outputs can be spent until either T or (more likely) B is mined.

In spite of the name FindLatestBefore used std::lower_bound to try
to find the earliest block with a nTime greater or equal to the
the requested value. But lower_bound uses bisection and requires
the input to be ordered with respect to the comparison operation.
Block times are not well ordered.
I don't know what lower_bound is permitted to do when the data
is not sufficiently ordered, but it's probably not good.
(I could construct an implementation which would infinite loop...)
To resolve the issue this commit introduces a maximum-so-far to the
block indexes and searches that.
For clarity the function is renamed to reflect what it actually does.
An issue that remains is that there is no grace period in importmulti:
If a address is created at time T and a send is immediately broadcast
and included by a miner with a slow clock there may not yet have been
any block with at least time T.
The normal rescan has a grace period of 7200 seconds, but importmulti
does not.

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.
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.
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?
The meaning is clear from the context, and we're inconsistent here.
Also save typing when using named arguments.
- `bitcoinaddress` -> `address`
- `bitcoinprivkey` -> `privkey`
- `bitcoinpubkey` -> `pubkey`
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.

This change removes a mapValue.erase("version") statement which deletes a
mapValue entry that never existed. The statement was mistakenly added in commit
865c3a2383 in 2010 and is harmless but confusing.
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.
Remove the nType and nVersion as parameters to all serialization methods
and functions. There is only one place where it's read and has an impact
(in CAddress), and even there it does not impact any of the recursively
invoked serializers.
Instead, the few places that need nType or nVersion are changed to read
it directly from the stream object, through GetType() and GetVersion()
methods which are added to all stream classes.

999e4c9 wallet: Change CCrypter to use vectors with secure allocator (Wladimir J. van der Laan)
Recent discussion (in IRC meetings, and e.g. #8989) has shown a
preference for the default confirm target for smartfees to be 6 instead
of 2, to avoid overpaying fees for questionable gain.
6 is also a compromise between the GUI's pre-#8989 value of 25 and the
bitcoind `-txconfirmtarget` default of 2. These were unified in #8989,
but this has made the (overly expensive) default of 2 as GUI default.
Change CCrypter to use vectors with secure allocator instead of buffers
on in the object itself which will end up on the stack. This avoids
having to call LockedPageManager to lock stack memory pages to prevent the
memory from being swapped to disk. This is wasteful.
There are only a few uses of `insecure_random` outside the tests.
This PR replaces uses of insecure_random (and its accompanying global
state) in the core code with an FastRandomContext that is automatically
seeded on creation.
This is meant to be used for inner loops. The FastRandomContext
can be in the outer scope, or the class itself, then rand32() is used
inside the loop. Useful e.g. for pushing addresses in CNode or the fee
rounding, or randomization for coin selection.
As a context is created per purpose, thus it gets rid of
cross-thread unprotected shared usage of a single set of globals, this
should also get rid of the potential race conditions.
- I'd say TxMempool::check is not called enough to warrant using a special
fast random context, this is switched to GetRand() (open for
discussion...)
- The use of `insecure_rand` in ConnectThroughProxy has been replaced by
an atomic integer counter. The only goal here is to have a different
credentials pair for each connection to go on a different Tor circuit,
it does not need to be random nor unpredictable.
- To avoid having a FastRandomContext on every CNode, the context is
passed into PushAddress as appropriate.
There remains an insecure_random for test usage in `test_random.h`.
