[PATH] ALTQ(9) codel algorithm implementation

[Ermal Luçi]

Hello,

at location [1] can be found a patch for Codel[3] algorithm implementation.

Triggered by a mail to the mailing lists[2] of OpenBSD i completed the
implementation for FreeBSD.

It allows to use codel as the single configured discipline on an interface.
Also it can be used as a sub discipline of existing queueing disciplines
already present.

The work has been tested and confirmed working without issues in pfSense.

Any objections on pushing this into FreeBSD?
