Add support for the meta l4proto type. This is used in the inet table to
match on the transport layer protocol without requiring the network layer
protocol to be known, allowing to use transport header matches that apply
to both IPv4 and IPv6.

Add support for the meta nfproto type, which refers to the AF from the
netfilter hook ops. This is needed to get the actual family of a packet
in the dummy NFPROTO_INET family.

The following two patches will add two new meta expression types that are
used as dependencies in the inet table. To reuse the existing dependency
generation code, add a slightly hackish way to specify meta expressions
as payload dependencies.

Add a helper function which is to be used to update the protocol update.

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.
