Unreleased

Fixed WalkFrom on S3 and GCS when both Prefix and StartingPoint was provided.

Added Clonable interface so you can call dstore.Clone(ctx) on a remote store, instantiate a new network client and context.
Added dstore.ReadObject to easily read a single file from a fileURL.
Added dstore.NewStoreFromFileURL to replace dstore.NewStoreFromURL which was not clear that it's usage is meant to create a store from a file directly.
Added dstore.OpenObject that is able to open a single store element without having to create a separate store, this is a shortcut for splitting the path & filename, creating a new store from the path and then calling store.OpenObject.
Added Store::BaseURL() to retrieve the underlying URL of the store.

Improved 'Walk' speed on gstore by 25% by only fetching 'Name'
Store dstore.MockStore now opened up public access to Files to easily get all written content.
BREAKING: MockStore's SubStore method has changed behavior. It now removes the prefix from files already present, to conform to the behavior of other stores. This might affect your use of MockStore::SetFile() in tests.
The Walk() and ListFiles() methods does not have an ignoreSuffix parameter anymore. This is managed internally by the LocalStore which was the only one that needed it, when writing temporary files (and renaming afterwards). Simplifies it for everyone else.
The dstore.NewLocalStore (local store implementation) sanitize the input if it does not start with file://.
BREAKING: The NewLocalStore now takes a *url.URL object instead of a string. Just pass a &url.URL{Scheme: "file", Path: originalString} to fix your code, if you're using NewLocalStore directly and not the recommended NewStore.

Deprecated The method dstore.NewStoreFromURL is deprecated, use dstore.NewStoreFromFileURL which is clearer in semantics.
