From: Rafał Miłecki <rafal@milecki.pl>

fwsignal is only used by bcdc. Create new protocol interface functions
for core code to perform proto specific (de)initialization. This makes
core agnostic to the protocol which will allow further optimizations.
We will be able to avoid compiling unused protocols or modularize them.
