mpd-3.16 and PPPoE server mode on 5.2.1-RELEASE

[Alexander Motin]

Hi.

There is a two problems with support of PPPoE in mpd under 5.x:
1. sometimes loading of netgraph modules on request cause system crash. 
(You can compile in all required modules.)
2. PPPoE in mpd do not works now on 5.x because of ununderstandible 
changes in ng_tee shutdown mechanism. (Now ng_tee don't connect left and 
right hooks on shutdown) So mpd now can't handle incoming PPPoE 
connections right.
