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
