1) Fix mempool limiting for PrioritiseTransaction
Redo the feerate index to be based on mining score, rather than fee.
Update mempool_packages.py to test prioritisetransaction's effect on
package scores.
2) Update replace-by-fee logic to use fee deltas
3) Use fee deltas for determining mempool acceptance
4) Remove GetMinRelayFee
One test in AcceptToMemoryPool was to compare a transaction's fee
agains the value returned by GetMinRelayFee. This value was zero for
all small transactions. For larger transactions (between
DEFAULT_BLOCK_PRIORITY_SIZE and MAX_STANDARD_TX_SIZE), this function
was preventing low fee transactions from ever being accepted.
With this function removed, we will now allow transactions in that range
with fees (including modifications via PrioritiseTransaction) below
the minRelayTxFee, provided that they have sufficient priority.

We used to have a trickle node, a node which was chosen in each iteration of
the send loop that was privileged and allowed to send out queued up non-time
critical messages. Since the removal of the fixed sleeps in the network code,
this resulted in fast and attackable treatment of such broadcasts.
This pull request changes the 3 remaining trickle use cases by random delays:
* Local address broadcast (while also removing the the wiping of the seen filter)
* Address relay
* Inv relay (for transactions; blocks are always relayed immediately)
The code is based on older commits by Patrick Strateman.

CWalletTx::GetAmounts could not find output address for null data transactions, thus issuing an error in debug.log. This change checks to see if the transaction is OP_RETURN before issuing error.

- Avoids string typos (by making the compiler check)
- Makes it easier to grep for handling/generation of a certain message type
- Refer directly to documentation by following the symbol in IDE
- Move list of valid message types to protocol.cpp:
protocol.cpp is a more appropriate place for this, and having
the array there makes it easier to keep things consistent.

Ever since we #5913 have been sending invalid reject messages
for transactions and blocks.
test: Add basic test for `reject` code
Extend P2P test framework to make it possible to expect reject
codes for transactions and blocks.

This is a combination of 3 commits.
- Coinselection prunes extraneous inputs from ApproximateBestSubset
A further pass over the available inputs has been added to ApproximateBestSubset after a candidate set has been found. It will prune any extraneous inputs in the selected subset, in order to decrease the number of input and the resulting change.
- Moved set reduction to the end of ApproximateBestSubset to reduce performance impact
- Added a test for the pruning of extraneous inputs after ApproximateBestSet

Mempool requests use a fair amount of bandwidth when the mempool is large,
disconnecting peers using them follows the same logic as disconnecting
peers fetching historical blocks.

- Add new translations (finally, after a long time)
- update-translation script was not considering new translations - oops
- fixed this, also remove (nearly) empty translations
- Update translation process, it was still describing the old repository
structure
Use the score index on the mempool to only add sorted txs in order. Remove much of the validation while building the block, relying on mempool to be consistent and only contain txs that can be mined.
The mempool is assumed to be consistent as far as not containing txs which spend non-existent outputs or double spends, and scripts are valid. Finality of txs is still checked (except not coinbase maturity, assumed in mempool).
Still TestBlockValidity in case mempool consistency breaks and return error state if an invalid block was created.
Unit tests are modified to realize that invalid blocks can now be constructed if the mempool breaks its consistency assumptions and also updated to have the right fees, since the cached value is now used for block construction.

The score index is meant to represent the order of priority for being included in a block for miners. Initially this is set to the transactions modified (by any feeDelta) fee rate. Index improvements and unit tests by sdaftuar.
Store sum of legacy and P2SH sig op counts. This is calculated in AcceptToMemory pool and storing it saves redoing the expensive calculation in block template creation.
