Support for PSR-17 HTTP Message Factories has been added.

PSR-17 HTTP Factories are intended to be used by PSR-15 request handlers
in order to create PSR-7 compatible message objects.

Classes may use dependency injection to use any of the available PSR-17
HTTP Factory interfaces.

The Request/Response base class (Message) is adapted to be able to lazily
initialize a stream when getBody() is called.
This is done as the PSR (Stream)RequestFactoryInterface does not allow
to control Stream properties. Therefore it is a performance
optimization to defer initialization. It is likely, that a new
Stream will be added to a Request with withStream() anyway.
(Which would mean resources for the intermediate stream would have
been wasted)

Furthermore some DocBlocks are adapted to reflect the variadic
UriInterface/StreamInterface parameters that are already handled in
code but were not documented. These cases are needed/required
by the PSR-17 factory implementation now.
