This function cleans up VEVENT, VJOURNAL, VTODO and VTIMEZONE items which are to be imported into Evolution.
Using VTIMEZONE definitions is problematic because they cannot be updated properly when timezone definitions change. They are also incomplete (for compatibility reason only one set of rules for summer saving changes can be included, even if different rules apply in different years). This function looks for matches of the used TZIDs against system timezones and replaces such TZIDs with the corresponding system timezone. This works for TZIDs containing a location (found via a fuzzy string search) and for Outlook TZIDs (via a hard-coded lookup table).
Some programs generate broken meeting invitations with TZID, but
without including the corresponding VTIMEZONE. Importing such
invitations unchanged causes problems later on (meeting displayed
incorrectly, e_cal_component_get_as_string()
fails). The situation
where this occurred in the past (found by a SyncEvolution user) is
now handled via the location based mapping.
If this mapping fails, this function also deals with VTIMEZONE conflicts: such conflicts occur when the calendar already contains an old VTIMEZONE definition with the same TZID, but different summer saving rules. Replacing the VTIMEZONE potentially breaks displaying of old events, whereas not replacing it breaks the new events (the behavior in Evolution <= 2.22.1).
The way this problem is resolved by renaming the new VTIMEZONE definition until the TZID is unique. A running count is appended to the TZID. All items referencing the renamed TZID are adapted accordingly.
