2dfeaa1 limitfreerelay edge case bugfix: (ptschip)

8504867 Save the last unnecessary database read (Alex Morcos)
|

Add a configuration option `-permitrbf` to set transaction replacement policy
for the mempool.
Enabling it will enable (opt-in) RBF, disabling it will refuse all
conflicting transactions.

45b8e27 -bytespersigop option to additionally limit sigops in transactions we relay and mine (Luke Dashjr)
|
|
|
|
If a new transaction will cause limitfreerelay
to be exceeded it should not be accepted
into the memory pool and the byte counter
should be updated only after the fact.

After discussion in #7164 I think this is better.
Max tip age was introduced in #5987 to make it possible to run
testnet-in-a-box. But associating this behavior with the testnet chain
is wrong conceptually, as it is not needed in normal usage.
Should aim to make testnet test the software as-is.
Replace it with a (debug) option `-maxtipage`, which can be
specified only in the specific case.

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.

- 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.

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.

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.

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.

But keep translating them in the GUI.
This - necessarily - requires duplication of a few messages.
Alternative take on #7134, that keeps the translations from being wiped.
Also document GetWarnings() input argument.
Fixes #5895.

Previously this logic could erroneously filter a MSG_BLOCK inventory message.
