<p>This function cleans up VEVENT, VJOURNAL, VTODO and VTIMEZONE
items which are to be imported into Evolution.</p>
<p>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).</p>
<p>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, <a class="link" href="ECal.html#e-cal-get-component-as-string" title="e_cal_get_component_as_string ()"><code class="function">e_cal_get_component_as_string()</code></a> fails). The situation
where this occurred in the past (found by a SyncEvolution user) is
now handled via the location based mapping.</p>
<p>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 &lt;= 2.22.1).</p>
<p>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.</p>

<p>This function cleans up VEVENT, VJOURNAL, VTODO and VTIMEZONE
items which are to be imported into Evolution.</p>
<p>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).</p>
<p>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, <a class="link" href="ECal.html#e-cal-get-component-as-string" title="e_cal_get_component_as_string ()"><code class="function">e_cal_get_component_as_string()</code></a> fails). The situation
where this occurred in the past (found by a SyncEvolution user) is
now handled via the location based mapping.</p>
<p>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 &lt;= 2.22.1).</p>
<p>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.</p>
