Split out methods to every module, apart from 'help' and 'stop' which
are implemented in rpcserver.cpp itself.
- This makes it easier to add or remove RPC commands - no longer everything that includes
rpcserver.h has to be rebuilt when there's a change there.
- Cleans up `rpc/server.h` by getting rid of the huge cluttered list of function definitions.
- Removes most of the bitcoin-specific code from rpcserver.cpp and .h.
Continues #7307 for the non-wallet.
In order to speed up block propagation, it is possible for some blocks
to arrive out of order due to propagation delays combined with 2 or
more blocks mined very quickly.
Additionally futurestamping blocks allows a high hash rate miner to
produce blocks that would be valid after a passage of time.
Previously such blocks triggered an extreme response that banned the
peer that broadcast it. Since these are temporary issues, if the block
is still valid when it is within the allowed timestamp window, this
update will process it normally.
Change the few occurrences of the deprecated `auto_ptr` to c++11 `unique_ptr`.
Silences the deprecation warnings.
Also add a missing `std::` for consistency.
