* Added ConditionalHeaderUtil, a conditional request helper class meant
for composition into Handler. I evaluated the composer package
micheh/psr7-cache for this role but I decided that I prefer DIY
code rather than some rather ugly glue.
* Check conditional request headers prior to entry into
Handler::execute(). Contrary to what was previously documented, use
the results of getLastModified() and getETag() to set headers in the
response. This is convenient and can be overridden in the Handler if
desired by overriding a one-line function.
* Instead of locking up header parsing inside ConditionalHeaderUtil as
was done in micheh/psr7-cache, make a start on a new reusable header
parsing framework, with recursive descent parsers for HTTP-date and
IfNoneMatch.

Just handle a HEAD request as a GET request, if no specific HEAD handler
exists. This is simple and similar to what the rest of MediaWiki does in
response to a HEAD request.

* Add ResponseFactory::createLocalizedHttpError(), which generates a
JSON response body from a MessageValue
* ResponseFactory::__construct() accepts an array of TextFormatter
objects. For ease of testing, the array may be empty. The integrated
ResponseFactory has a TextFormatter for English, and one for
$wgContLang if that is different.
* Use createLocalizedHttpError() to show helpful error messages for
errors generated by Router.

Parameter validation is based on parameter definitions like those in the
Action API, using the new ParamValidator library. Handlers should use
the provided Handler methods to access parameters rather than fetching
them directly from the RequestInterface.
Body validation allows the handler to have the (non-form-data) body of a
request parsed and validated. The only validator included in this patch
ignores the body entirely; future patches may implement validation for
JSON bodies based on JSON schemas, or the like.

Protect private wikis by providing basic read restrictions,
closely following the example of the action API.
The BasicAccess module provides a narrow interface for this
functionality, without exposing the whole session/user concept to the
router.
Also, add RouterTest and fix a bug in Router::getRelativePath() thus
discovered.

Instead of providing the Router as a service, as previously proposed,
inject it into the handler via init().

* Factor out json_encode() call into ResponseFactory::encodeJson().
* Add createJson() and standardize on JSON for 4xx and 5xx responses
* Add methods for redirect generation, providing an HTML link in the
body as recommended by RFC 7231
Most of the code was written by Gergő Tisza. The differences compared to
I747e34faecbcd are:
* Remove JsonResponse.
* Swap parameter order of createJson() reflecting the fact that the
value is now usually provided.
* Remove unnecessary ResponseFactory::setStatus()
* Don't do ['code' => 'http500'] by default, use httpCode and httpReason
to provide that information
* In createFromReturnValue(), don't wrap numerically-indexed arrays.
* Added tests.

Add some of the basic REST API class hierarchies:
* EntryPoint
* Router
* Request
* Response
* Handler
The actual entry point file rest.php has been moved to a separate
commit, so this is just an unused library and service.
