Changelog-Fixed: Protocol: we will upfront reject channel_open which asks for a zeroconf channel unless we are going to do a zerconf channel.
I tested this indeed breaks if we don't accept it, then implemented
the code to accept it.

Changelog-Fixed: protocol: We now correctly accept the `option_scid_alias` bit in `open_channel` `channel_type`.
Changelog-Deprecated: protocol: Not setting `option_scid_alias` in `option_channel` `channel_type` for unannounced channels.
We make it a first-class citizen internally, even though we won't use
it over the wire (at least, non-experimental builds). This scheme
follows the latest draft, in which features are flagged compulsory.
We also add several helper functions.
Since uses the *even* bits (as per latest spec), not the *odd* bits,
we have some other fixups.
