Nick Craig-Wood 6381959850 dropbox: support Dropbox content hashing scheme - fixes #1302
* add support to hashing module
  * add dbhashsum to list the hashes
  * add support to dropbox module

This means objects up and downloaded to/from Dropbox will have their
hashes checked.

Note after this change local objects are calculating MD5, SHA1 and
DBHASH which is excessive and needs to be fixed.

// Integration tests - test rclone by doing real transactions to a
// storage provider to and from the local disk.
//
// By default it will use a local fs, however you can provide a
// -remote option to use a different remote. The test_all.go script
// is a wrapper to call this for all the test remotes.
//
// FIXME not safe for concurrent running of tests until fs.Config is
// no longer a global
//
// NB When writing tests
//
// Make sure every series of writes to the remote has a
// fstest.CheckItems() before use. This make sure the directory
// listing is now consistent and stops cascading errors.
//
// Call fs.Stats.ResetCounters() before every fs.Sync() as it uses the
// error count internally.
