  Log Message:
  -----------
  lib-sieve: util: rfc2822: Added rfc2822_header_write_address() which allows adding a header with one or more addresses.

It applies UTF8 encoding only when the address string somehow contains 8-bit characters.
Sieve addresses are supposed to have any UTF8 characters in the phase MIME-encoded, not literal 8-bit characters.
However, this has been allowed from the beginning, so disabling the old behavior may break existing installations.
This function allows supporting both options.

  Log Message:
  -----------
  lib-sieve: Fixed writing address headers to outgoing messages.

It erroneously applied another layer of MIME header encoding.
The problem is that existing Sieve scripts may rely on this behaviour; i.e. scripts may contain addresesses with literal UTF8 in the phrase part.
Therefore, this change allows both behaviors.
