bf66a93cb Correctly seed the liquidv1 paklist pre-dynafed (Gregory Sanders)
Pull request description:
Currently PAK is blank for anyone running on liquidv1 network. This is wrong.
No PAK list changes are expected prior to dynafed roll-out, so this should remain constant until activation.

674f3c747 When RPC server disabled, only warn on validatepegin failure (Gregory Sanders)
Pull request description:
QT starts up normally, and fails when `-server=1` is set, and continues otherwise, by turning off peg-in validation.
This should be tested on liquidv1 with fresh syncs.

Pull request description:
Adds to `createrawtransaction` the fields `pegin_bitcoin_tx`, `pegin_txout_proof`, and `pegin_claim_script` so that raw transactions can contain peg-in inputs too.
Since `ConstructTransaction` is used by `createpsbt` and `walletcreatefundedpsbt` but those should not support peg-ins yet (the peg-in data should go into PSBT fields for peg-ins but those don't exist yet), an argument is added to it to optionally reject peg-in data.

67a669e69 Take mempool locks when doing compact block RPC calls touching mempool (Gregory Sanders)
Pull request description:
This may help reduce the failures in `feature_blocksign.py` that seem to occur fairly often. It could be that the mempool is in an inconsistent state, which messed up compact block finalization.

It is not included in the signature hash.
The sighash byte MUST be SIGHASH_ALL to avoid malleability.

Pull request description:
This is a proposal implementation of something myself and Andrew have been working on, to enable dynamic membership in the blocksigning set, fedpeg signing set, and under the same coordination mechanism, the PAK enforcement.
At a really high level:
1) If 4/5 of last N(what we call an epoch length) blocks signal desire for a change in the parameters of the system, they are replaced with the proposed. These changes can be proposed/driven by `getnewblockhex`.
2) Once dynamic federations is active(versionbits deployment), signblockscripts can only be native segwit scripts, in other words, must be a version byte followed by the witness program. The blockheader now has a witness stack as well.
3) The fedpegscript of last N epochs are both allowed as a grace period for users putting money into the system.
4) PAK enforcement has been upgraded to consensus-enforcement once dynamic federations activates
A design document is forthcoming.
