bitcoin: src/script.cpp annotate

annotate src/script.cpp @ 2277:0dcf927bc6b2 draft

Further reduce header dependencies This commit removes the dependency of serialize.h on PROTOCOL_VERSION, and makes this parameter required instead of implicit. This is much saner, as it makes the places where changing a version number can have an influence obvious.
