Cleanup: "postconf" commands in postfix-install needed to

be updated before master.cf was installed. Reported by

Sahil Tandon. File: postfix-install.

Cleanup: support for parameter name spaces for master.cf
|

entries. With this, postconf should no longer log false
|
||||
warnings for "-o user-defined-name=value" in master.cf. As
|
||||
a benefit, it will warn for user-defined parameters with
|
||||
"name=value" entries that are unused because they are hidden
|
||||
by master.cf "-o name=value" entries with the same parameter

Eliminated the postconf limitation documented on 20111113 as "lack
|
||||
of support for per-service parameter name spaces in master.cf,

meaning that "-o user-defined-name=value" always results in an
