Import btcnet repo into chaincfg directory.

This commit contains the entire btcnet repository along with several
changes needed to move all of the files into the chaincfg 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 btcnet test files have been changed to the
  new location
- All references to btcnet as the package name have been changed to
  chaincfg
- The coveralls badge has been removed since it unfortunately doesn't
  support coverage of sub-packages

This is ongoing work toward #214.
