[RFC PATCH 00/20] Context typed filters

[Asbjørn Sloth Tønnesen]

This RFC patch series is a first stab, at adding some syntactic sugar
making it more plessant to implement non-trivial dual-stack configurations,
like https://bgpfilterguide.nlnog.net/

I'm not completely happy with the naming at this stage, but I want to
get this series out before 36C3 ends.

Looking forward to your feedback.
