Without this, users of this library wouldn't be able to issue GetBlock
requests to nodes which haven't updated to support the latest request
format, namely the use of a single `int` parameter to denote verbosity
instead of two `bool`s.
This change makes btcd's getblock command match bitcoind's. Previously
the default verbosity was 0, which caused errors when using the
rpcclient library to connect to a bitcoind node - getblock would
unmarshall incorrectly since it didn't expect a verbosity=1 result when
it did not specify verbosity.
Due to differences in how getblock returns data based on the provided verbosity parameter, it's necessary
to have two separate return types based on verbosity. This necessitates a separate unmarshalling function
(represented throughout rpcclient/chain.go as Result.Receive()) to ensure that data is correctly unmarshalled
and returned to the user.
This commit contains the entire btcrpcclient repository along with
several changes needed to move all of the files into the rpcclient
directory in order to prepare it for merging. This does NOT update btcd
or any of the other packages to use the new location as that will be
done separately.
- All import paths in the old btcrpcclient files have been changed to
the new location
- All references to btcrpcclient as the package name have been changed to
rpcclient
