When receiving unwanted headers from a peer, first check whether we have
recent "best known block" state for that peer. If not, accept one batch
of headers to refresh it. Otherwise, we can become stuck in a state where
we need blocks, but we don't know which peers have those blocks available.
This especially happens during startup, when we don't have this information
for any peers until we start processing header messages.

Pull request description:
Currently using liquidtestnet requires a big config file, which is error-prone and uncomfortable for users, this MR adds support for just using `-chain=liquidtestnet`.
There are a few things that need to be discussed/addressed
1. Main port (currently set to 18891 because that's the one used originally, and the one that's configured in `liquidtestnet.com`)
1. RPC and extra ports, I just chose some non-overlapping ports that are "close" to the ones in the other liquid/elements networks.
1. Icon color, I just used something different than `liquidv1` and `elementsregtest`, suggestions accepted 😉
1. `liquid-testnet.blockstream.com` is still using port 18892, it will be changed to 18891 soon.
1. both seeds are just CNAME dns records at the moment, they should be changed to real seed nodes (no changes in code required, but important for review)

Make these two functions available to external callers.
CreateBlindValueProof is a wrapper around the static function to avoid
requiring callers to parse things into secp256k1 objects.
It is arguable whether attempting a value proof without an asset
commitment should be treated as incomplete or incorrect blinding. Since
the asset commitment is required to produce the value proof in the first
place, failing to provide it in the source PSET and thus at this call
site is treated as an error.
This does not change the existing behaviour since a missing asset
or value commitment in this function would already cause it to fail.
Future work on the blinding iterface should likely return the blinding
state directly from the verify calls and remove the duplicated mapping of
blinding error codes to transaction blinding error codes, instead of the
verify functions returning just true/false.
