89cc033428 Be much more precice in msg.Len() 
There is still a one-off in EDNS0 records, but I'm not too bothered with
that one.

56e0bb46d8 Remove packLen() and fix bug in Len() 
packLen() was a featureless mirror of Len(). Remove it, and just use
Len() internally too.
Fix bug in Len() too, where the length of the additional section was
not counted.

4f6fef6777 If the TC bit is set return a valid but smaller message 
If the TC bit is set in a message, we will probably try to parse
half a message, which will fail. To fix this just return a message
header and the question section and don't parse the rest.

2cfad667d7 msg.Copy() makes a deep-copy of the msg object 
There was a copy function that did shallow copies of the msg
object. Export it and make it support proper deep copying.

d18d87b37d Introduce msg.PackBuffer() - it's like msg.Pack() but can reuse a byte buffer 
msg.Pack() always allocates a byte slice. This is good for simplicity,
but in a serious application it's preferable to reuse byte slices to
reduce the GC overhead. This patch introduces a new public method:
PackBuffer(). It's exaclty like Pack() but is able to reuse a
given byte slice. It will still allocate a new slice if the given one
is too small.

9f5db7b72c Disable the unfinished CAA support 
CAA was partially implemented, it's better to do it 100% until that
time handle CAA as an unknown record.

9c1ee5d5ca Update IsDomainName 
This new functions just compiles the domain to wire format, if that
works, the name is deemed OK. It is also much less strict than the
older code. Almost everything is allowed in the name, except two
dots back to back (there is an explicit test for that).

b6a2d1fb5e Allow empty rdata in records 
Empty or no rdata is allowed for dynamic updates, so test if this
works for packing/unpacking. It only fails for TSIG (which is
never seen in zone files), SOA (which is not seen like this in dyn.
updates) and WKS (just an old record).

fdcdc6dbf6 Add test to zero rdata (for dyn updates) 
This triggerd a bunch of failures, the most important one
is the packing and zero length domain name now works.
