Dave Collins b69a849114 Import btcchain repo into blockchain directory.
This commit contains the entire btcchain repository along with several
changes needed to move all of the files into the blockchain 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 btcchain test files have been changed to
  the new location
- All references to btcchain as the package name have been changed to
  blockchain
