ng_pppoe: introduce new sysctl net.graph.pppoe.lcp_pcp

This fixes incomplete commit 2e547442ab3822d3d7c46a68f152032ef5fe337c

New sysctl allows to mark transmitted PPPoE LCP Control
ethernet frames with needed 3-bit Priority Code Point (PCP) value.
Confirming driver like if_vlan(4) uses the value to fill
IEEE 802.1p class of service field.

This is similar to Cisco IOS "control-packets vlan cos priority"
command.

It helps to avoid premature disconnection of user sessions
due to control frame drops (LCP Echo etc.)
if network infrastructure has a botteleck at a switch
or the xdsl DSLAM.

ng pppoe(4): Add the required NET_EPOCH section to the hook
disconnection function.

Disconnecting hooks are called outside of NET_EPOCH, but
ng_pppoe_disconnect() calls NG_SEND_DATA_ONLY() which should be called
in NET_EPOCH.

While here remove an unneeded EPOCH entry (which wasn't wide enough to cover

ng_pppoe(8): add support for user-supplied Host-Uniq tag.

A few ISP filter PADI requests based on such tag,
to force the use of their own routers.
The custom Host-Uniq tag is passed in the NGM_PPPOE_CONNECT
control message, so it can be used with FreeBSD ppp(8)
and mpd without any other change.

Add support to send and receive PADM messages,
HURL and MOTM, often used by service providers to provide
ACS information and other configuration settings
to the user CPE.
