The changes simplify the `req` method by moving the
authentication-related code into the API.
This makes it easy to add additional authentication methods.
The API introduces an `Authorizer` that acts as an
authenticator factory. The authentication flow itself
is divided down into `Authorize` and `Verify` steps in order
to encapsulate and control complex authentication challenges.
The default `NewAutoAuth` negotiates the algorithms.
Under the hood, it creates an authenticator shim per request,
which delegates the authentication flow to our authenticators.
The `NewEmptyAuth` and `NewPreemptiveAuth` authorizers
allow you to have more control over algorithms and resources.
The API also allows interception of the redirect mechanism by setting
the `XInhibitRedirect` header.
This closes: #15#24#38
Client.Stat was not returning a proper Go err for not found files, the
ideal way to check this is using `errors.Is(err, fs.ErrNotExist)` but
the client was returning a generic error.
I've updated the `propfind` to take 404 errors into account, retuning
the above error making easier to evaluate that kind of situations.
* bubble up request errors [#28]
* inhibit stream close on request
* add `StatusError`
* `PUT`: check if given target is a directory
* Revert "inhibit stream close on request"
Cherry-picked into branch dev-bodyclosing.
This reverts commit 2889239999.

* method for creating parent collection was added to Client struct
"func (c *Client) createParentCollection(itemPath string) error" was added to request.go file
* using Client's method to create parent collection
in following methods:
Client.Write()
Client.WriteStream()
Client.copymove()
deadlock is impossible in method Client.copymove() because of paragraph #6 section 9.8.5 (https://tools.ietf.org/html/rfc4918#section-9.8.5) and paragraph #6 section 9.9.4 (https://tools.ietf.org/html/rfc4918#section-9.9.4) of RFC 4918 (https://tools.ietf.org/html/rfc4918)
* install dependencies script was added to Travis-CI file
* testing was added to Travis-CI file
* error wrapping was removed from Client.put() method
* using an early return on error in case of 409 in Client.Write() method
