* @comps: (element-type icalcomponent) (allow-none): a list of #icalcomponent
* instances which also have to be patched; may be %NULL
* @tzlookup: a callback function which is called to retrieve
* a calendar's VTIMEZONE definition; the returned
* definition is *not* freed by e_cal_client_check_timezones()
* (to be compatible with e_cal_get_timezone());
* NULL indicates that no such timezone exists
* or an error occurred
* @ecalclient: an arbitrary pointer which is passed through to
* the @tzlookup function
* @cancellable: a #GCancellable to use in @tzlookup function
* @error: an error description in case of a failure
*
* 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_get_component_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 is 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.
*
* Returns: %TRUE if successful, %FALSE otherwise.
*
* Since: 3.2
