Incompatible changes with snapshot 201800107

This release changes the format of 'full name' information in
Postfix-generated From: headers, when a local program such as
/bin/mail submits a message without From: header.

Postfix-generated From: headers with 'full name' information are
now formatted as "From: name <address>" by default. Specify
"header_from_format = obsolete" to get the earlier form "From:
address (name)". See the postconf(5) manpage for more details.
