Concurrent Queue

Implement a thread-safe zero allocation queue with the following properties:

• It has a fixed maximum size set at initialization.
• Push(val int) error adds an item to the queue. If the queue is full, it should return ErrQueueFull.
• Pop() int removes and returns first item from the queue. If the queue is empty, return -1.
• Peek() int returns first item from the queue. If the queue is empty, return -1.
• The queue must be safe to use from multiple goroutines simultaneously.
