A follow-up on bug 1608610. See comment 104 ( The code in calendar-migration-dialog.js needs to be split up so the whole file doesn't need to be included in main window (messenger.xhtml) scope, but we still prevent this error on first run with a fresh profile:

  Migrator error: ReferenceError: gDataMigrator is not defined calendar-management.js:423
    initHomeCalendar chrome://calendar/content/calendar-management.js:423
    loadCalendarManager chrome://calendar/content/calendar-management.js:122
    commonInitCalendar chrome://calendar/content/calendar-chrome-startup.js:28
    ltnOnLoad chrome://lightning/content/messenger-overlay-sidebar.js:386
    (Async: EventListener.handleEvent)
    <anonymous> chrome://lightning/content/messenger-overlay-sidebar.js:753

Also some of the code in calendar-migration-dialog.js can be removed (e.g. for migrating data from Sunbird).

Part1 - Remove ancient code for migrating from sunbird and early calendar add-on.

Attachment #9124900 - Flags: review?(geoff)

part2 - Replace ad hoc logger function with console.debug.

Attachment #9124901 - Flags: review?(geoff)

part3 - Split migration code into two files, one for the main window and one for the migration dialog.
I confirmed that the "gDataMigrator" is not defined" error did not occur with a new profile.
