nftables: generic procotol contexts
Currently the context of higher layer protocols is specific to payload expressions with some special cases for meta IIFTYPE expressions. This approach has a few shortcomings, concretely there are more expression types which define upper layer protocols like the ct expression and two upcoming new types for the meta expression. Replace the payload context by a generic protocol context to deal with this. This patch just splits off the requires parts from the payload expression without any functional changes, the following patches will add further functionality for other expressions.
