High-performance PSR-7 HTTP server, PHP load balancer and process manager.

Features:
--------
- PSR-7 HTTP server (file uploads, error handling, static files, hot reload, middlewares, event listeners)
- extendable service model
- no external services, drop-in (based on [Goridge](https://github.com/spiral/goridge))
- load balancer, process manager and task pipeline
- frontend agnostic (queue, REST, PSR-7, async php, etc)
- works over TCP, unix sockets and standard pipes
- automatic worker replacement and safe PHP process destruction
- worker lifecycle management (create/allocate/destroy timeouts)
- payload context and body
- control over max jobs per worker
- protocol, worker and job level error management (including PHP errors)
- memory leak failswitch
- very fast (~250k calls per second on Ryzen 1700X over 16 threads)
- works on Windows

Example [worker](https://github.com/spiral/roadrunner/blob/master/php-src/tests/http/client.php).

Examples:
--------

```go
p, err := rr.NewPool(
    func() *exec.Cmd { return exec.Command("php", "worker.php", "pipes") },
    rr.NewPipeFactory(),
    rr.Config{
        NumWorkers:      uint64(runtime.NumCPU()),
        AllocateTimeout: time.Second,              
        DestroyTimeout:  time.Second,               
    },
)
defer p.Destroy()

rsp, err := p.Exec(&rr.Payload{Body: []byte("hello")})
```
```php
<?php
/**
 * @var Goridge\RelayInterface $relay
 */

use Spiral\Goridge;
use Spiral\RoadRunner;

$rr = new RoadRunner\Worker($relay);

while ($body = $rr->receive($context)) {
    try {
        $rr->send((string)$body, (string)$context);
    } catch (\Throwable $e) {
        $rr->error((string)$e);
    }
}
```
