a56060b558 Cleanups for Copy() 
Docs and slight code formatting issues.

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.

Closes #70:

7a27e05cb7 Remove setting compress to nil 
Useless operation as compress is already nil from the
initialization.

70ee966106 Fix the unknown record sign test 
Don't make up new error in msg.Pack when there are perfectly fine
errors to return.

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.

9fa50d8ac2 Fix the nsec/3 length calculation 
This overshoots, 'cause it only counts the windows, not the

61919d8713 Add all the compressible types to Len() 
Len() now performs its duty, question is, *is* this now faster/better
than just packing a Msg, checkings its lenght and discarding the buffer.

1ad76fe65b Added packLen 
packLen() returns the length of an uncompressed packet buffer, this
is used when packing a packet. This is needed for compression. When
compression is used, we first create the full packet and *then*
compress it. If we use Len() which accounts for compression, we can
get buffer overruns, when packing the (then still uncompressed) packet.

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)
