Jeffrey Czyz	ccd11fc35a	Support all shutdown scripts defined in BOLT 2 ... KeysInterface::get_shutdown_pubkey is used to form P2WPKH shutdown scripts. However, BOLT 2 allows for a wider variety of scripts. Refactor KeysInterface to allow any supported script while still maintaining serialization backwards compatibility with P2WPKH script pubkeys stored simply as the PublicKey. Add an optional TLV field to Channel and ChannelMonitor to support the new format, but continue to serialize the legacy PublicKey format.	2021-08-09 15:55:26 -05:00
Jeffrey Czyz	ecc70757f9	Add ShutdownScript for BOLT 2 acceptable scripts ... BOLT 2 enumerates the script formats that may be used for a shutdown script. KeysInterface::get_shutdown_pubkey returns a PublicKey used to form one of the acceptable formats (P2WPKH). Add a ShutdownScript abstraction to encapsulate all accept formats and be backwards compatible with P2WPKH scripts serialized as the corresponding PublicKey.	2021-08-09 15:55:25 -05:00
