8bd3ac773f Add support for custom EDNS options in GoDNS. 
A handful of EDNS options have been standardized, and they each have a type defined in GoDNS.  However there is currently no way a development team can use GoDNS with internally defined options, or with new options that may be proposed in the future.

This change solves the problem by giving users an EDNS0_CUSTOM type to allow clients to send, and servers to receive, custom EDNS options.

67945c119e A bunch of golint fixes 
The proposed vars names are a nono, because they break the API.
Things left: document each RR and zscan_rr.go has some funcky if-then-elses.

009c72175f Update documentation references for EDNS0 and EDNS0_SUBNET.

e32b05768f Fix length overrun in EDNS0 parsing. 
Original text: (in Dutch)

Ik kreeg crashes (index out of range) in het parsen van een EDNS0_LLQ
optie, doordat de method: 'func (e *EDNS0_LLQ) unpack(b []byte)' een
byte slice van 1 byte groot kreeg waar dan meerdere uint16's uit gelezen
werden.

6ecde82c20 Remove UPDATE_LEASE to UL 
The "other" edns0 option will then become LONG_LIVED_QUERIES which
is way to long to be practical, so I want to make it LLQ, UPDATE_LEASE
then needs to be come UL.

This will probably impact no-one, because noone uses this (I hope)

0bcd43e7cc Use SourceNetmask to truncate IP addresses in EDNS-CLIENT-SUBNET packets 
OpenDNS returns SERVFAIL to the client if the address in the EDNS packet
is too long. The spec says to truncate it to the shortest possible address
when the SourceNetmask is applied.

cd10853288 Make Len() and Copy() private 
I don't think anybody will needs these, msg.Len() is still
available. Severly cuts back on the amount of exported functions.
