* Fix `Stream::read` when length parameter <= 0.
* `copy_to_stream` reads bytes in chunks instead of `maxLen` into memory.
* Fix `ServerRequest::getUriFromGlobals` when `Host` header contains port.
* Ensure `ServerRequest::getUriFromGlobals` returns a URI in absolute form.
* Allow `parse_response` to parse a response without delimiting space and reason.
* Ensure each URI modification results in a valid URI according to PSR-7 discussions.
  Invalid modifications will throw an exception instead of returning a wrong URI or
  doing some magic.
  - `(new Uri)->withPath('foo')->withHost('example.com')` will throw an exception
    because the path of a URI with an authority must start with a slash "/" or be empty
  - `(new Uri())->withScheme('http')` will return `'http://localhost'`
* Fix compatibility of URIs with `file` scheme and empty host.
* Added common URI utility methods based on RFC 3986 (see documentation in the readme):
  - `Uri::isDefaultPort`
  - `Uri::isAbsolute`
  - `Uri::isNetworkPathReference`
  - `Uri::isAbsolutePathReference`
  - `Uri::isRelativePathReference`
  - `Uri::isSameDocumentReference`
  - `Uri::composeComponents`
  - `UriNormalizer::normalize`
  - `UriNormalizer::isEquivalent`
  - `UriResolver::relativize`
* Deprecated `Uri::resolve` in favor of `UriResolver::resolve`
* Deprecated `Uri::removeDotSegments` in favor of `UriResolver::removeDotSegments`
