Context

This is the first part to answer issue #2035 (closed).

It implements some preparation work to separate internal operations. Mainly:

remove the unused operation_size function so that it does not get in our way;
extract some behavior related to internal operations in order to share them between internal and external operations;
find_entrypoint works at Michelson level (instead of Micheline);
have dedicated types in Apply_results for returning results of internal operations.
