Checks that we don't reject synthesized name of the maximum length by
mistake.

We overflow the size of name by prolonging a name of full length by
little bit.

As agreed, we don't provide the authority section for the original
DNAME/CNAME, only for the last target. As we don't chain, we don't
provide it at all.

It seems the RFC 2672 isn't too clear about it, but all checked
authoritative servers don't provide the authority section in case of
YXDOMAIN caused by too long synthesized name.

points to be considered with chaining.

They are almost the same right now, but they will be different once the
CNAME chaining is implemented.

No chaining yet.

* Fixed a comment
* Modified condition in MockZone to match the one in MemoryZone.

going to push without review.

 - separated the zone data and find() logic
 - cleanup unnecessary variables as a result
 - used zone data for test input when possible

using the new rrsetsCheck() framework.

The fix is for MXAlias: it didn't test what was to be tested: the intended
case is where MX exchange name is an alias:
cnamemx.example.com. MX 10 cnamemailer.example.com.
cnamemailer.example.com. CNAME www.example.com.
(and the test asks for cnamemx.example.com/MX)
but it tested the case where the owner name of MX is an alias
(ask cnamemailer.example.com/MX in the above example).

to reduce duplicate code.

 - shortened long lines for readability
 - make sure the canonical name of mailer.example.org has an address
   record; otherwise the test could result in a false negative.

omit authority data which has already been provided in the answer section from the authority section.
