[5.3] Add default parameters to UrlGenerator

[pilot911]

Adding global parameters like 'locale' for creating URL by named routers without passing smth like ['locale' => config('app.locale')] in every url generator on page.

app("url")->setDefaultParameters("locale", app()->getLocale());

and create URLs via

app('router')->pattern('locale', '(' . implode('|', config('app.locales')). ')');
app('router')->group(['domain' => '{locale}.telenok.com'], function ()
{
    app("router")->post("some-url", array("as" => "some-name", "uses" => "SomeClass@somemethod"));
});

Then instead of

<a href="{{  route("some-name") }}">.....</a>

you'll get

<a href="http://en.telenok.com/some-url">.....</a>

[pilot911]

Better set global url parameters in middleware like

<?php

namespace App\Http\Middleware;

use Illuminate\Foundation\Application;

class UrlGeneratorParameters {

    protected $app;

    public function __construct(Application $app)
    {
        $this->app = $app;
    }

    /**
     * Handle an incoming request.
     *
     * @param  \Illuminate\Http\Request  $request
     * @param  \Closure  $next
     * @return mixed
     */
    public function handle($request, \Closure $next)
    {
        $this->app->url->setDefaultParameters("locale", config('app.locale'));

        return $next($request);
    }
}

This implementation will not work because if you have some routes that do not need the default parameter you will end up appending it to the query string:

Route::as('something')->get('/foobar/{baz}', function () {

});

Route::get('/', function () {
    dd(route('something', ['baz' => 1, 'default' => 'something']));

    return view('welcome');
});
