xhci: defer roothub events processing

There are two new generic mechanisms, which are used in only one
instance.

First one is a simple wrapper for roothub event handlers that should run
in separate fibril. The usage can be seen at line 337, for example. The
mechanism just passes arguments to a newly created fibril.

The second is a bit more complex, and its purpose is to broadcast roothub
events to all fibrils that could wait for it. It's used to wait for port
reset complete at USB 2 ports. See rh_port_reset_sync.

Sorry for naming both mechanisms "rh_event", which could create
a confusion.
