Instead of going through the fmt package, we can use append int,

Implement SIG(0) signing and verification

This is based on @miekg's sig0 branch. That branch diverged from master
and I didn't want to wander off on a rebase.
As implemented there's no allowance for multi-envelope (TCP) support.
TODO:
* unpackUint32() could be moved out and used elsewhere
* tests
* multi-envelope support (if useful)

Reduce number of memory allocations in msg.Copy

Right now we allocate memory even for empty slices. This is inefficient, sticking "nil" as a slice is good enough if there are no items.

Update domain name and TXT string escape behaviour
...
Changes to domain name packing and unpacking:
* Escape dot, backslash, brackets, double-quote, semi-colon and space
* Tab, line feed and carriage return become \t, \n and \r
Changes to TXT string packing and unpacking:
* Escape backslash and double-quote
* Tab, line feed and carriage return become \t, \n and \r
* Other unprintables to \DDD
Stringers do the equivalent of putting domain names and TXT strings
to the wire and back.
There is some duplication of logic. I found performance suffered when
I broke the logic out into smaller functions. I think this may have
been due to functions not being inlined for various reasons.
