Wladimir J. van der Laan e6dcfeec05 refactor: Move GetDifficulty out of rpc/server.h
It has no business in `rpcserver.h`. Define it in the interface header
of the implementation unit `rpcblockchain` where it is defined.

Also modernize the signature to:

    double GetDifficulty(const CBlockIndex* blockindex = nullptr);

(remove `extern`, replace `NULL` with `nullptr`)
