Note that we unfortunately can't use a scripted diff here, as the
`sha256` symbol is also used for other instances (e.g. as function
in hashlib, or in the `UTXO` class in p2p_segwit.py).

Pull request description:
Retains the `-datacarrier*` args, marks them as deprecated, and does not require another startup argument for multiple OP_RETURN outputs.
If a user has set `-datacarriersize` the value is "budgeted" across all seen OP_RETURN output scriptPubKeys. In other words the total script bytes stays the same, but can be spread across any number of outputs. This is done to not introduce an additional argument to support multiple outputs.
I do not advise people use the option with custom arguments and it is marked as deprecated to not mislead as a promise to offer it forever. The argument itself can be removed in some future release to clean up the code and minimize footguns for users.

The current test directly uses invalidatblock to trigger
mempool re-entry of transactions. Unfortunately, the
behavior doesn't match what a real reorg would look like. As
a result you get surprising behavior such as the mempool
descendant chain limits being exceeded, or if a fork is
greater than 10 blocks deep, evicted block transactions stop
being submitted back into in the mempool.
Fix this by preparing an empty fork chain, and then
continuing with the logic, finally submitting the fork chain
once the rest of the test is prepared. This triggers a more
typical codepath.
Also, extend the descendant limit to 100, like ancestor
limit.
The previous diff touched most files in ./test/, so bump the headers to
avoid having to touch them again for a bump later.
