Implement basic IDNA support

Browse Source 
This patch implements the first steps of support for IDNA (Internationalized
Domain Names for Applications).

Internally, we maintain the byte-agnostic representation, including
configuration.

We support receiving IDNA mail over SMTP, which we convert to unicode for
internal handling.

Local deliveries are still kept agnostic.

For sending over SMTP, we use IDNA for DNS resolution, but there are some
corner cases pending in the SMTP courier that are tied with SMTPUTF8 and will
be fixed in subsequent patches.
