The last part of loading appointments and events is performed by four
"scan" functions called from io_load_app(). Failure in this part of data
load does not use io_load_error().
The four "scan" functions are changed to return an error message on
failure and NULL otherwise (the previous return value was not used).

New filter option: --filter-invert. When present it inverts (negates)
the other filter options combined. This is mostly useful with the -G
option (with -Q the output is limited by the query range (day range)).
The ouput from "calcurse -G <filter options>" is the (set) complement of
"calcurse -G <filter options> --filter-invert". Here <filter options>
may be any combination of filter options.

With the exception of filter.type_mask, a filter is only applied if set
explicitly on the command line with a filter option. Whether that is the
case, is determined by comparison with the initialization value. For
date related filters (start_from/to, end_from/to) that is -1, hence the
criterion is != -1, not >= 0.
In generel, a filter initialization value should be invalid (i.e. one
that cannot be set explicitly). As times before the epoch (1 January
1970 00:00:00 UTC) are negative, -1 is a valid Unix time. However, as it
cannot be set from the command line, it is probably no problem?

The number of seconds in a day and daylength in seconds differ when
Daylight Saving Time is in effect on two days of the year. The day when DST
takes effect is 23 hours long, and the day when DST ends is 25 hours long.
In the latter case the date changing thread wóuld enter a loop in the last hour
before midnight (in the former it would set the date an hour too late).
The next midnight is calculated through mktime(), invoked by date2sec().
Wrong daylength prevented appointments from being stored in the day vector and
caused them to be displayed wrongly in the appts panel.

Calcurse saves time and date information on disk as local time in readable text
file format. When loaded from disk or when entered by the user, local time is
converted to Unix time (seconds since 00:00:00, 1 January 1970). When
displayed, and later when saved to disk, the Unix time is converted back to
readable local time. Both conversions depend on DST.
Hence, if midnight for a day with DST in effect (i.e. local time) is converted,
increased with an amount and converted back, the amount has changed if DST is
_not_ in effect for the resulting time. In general, calculations on Unix time
variables should be used with caution because of the DST-dependent conversions.
Instead, the calculations should be performed on local time data with the help
of mktime().
The commit fixes start time for pasted appointments (ordinary and recurrent)
and the 'until'-date of recurrent appointments, pasted as well as new and
edited. The latter problem is slightly different in that the adjustment is a
number of days, as it is for exception dates.
Update of the date in parse_datetime() has been corrected to be similar to
update of the time, although no problem has been identified.

When checking whether an appointment belongs to a given day in
apoint_inday(), the return value was 0 if the end time of the
appointment matched 00:00 on that day (because we do not want to include
appointments starting on the day before and lasting until midnight).
However, this means that punctual appointments at 00:00 were not
included in any day. Fix the apoint_inday() logic to take this into
consideration.

Since the result of localtime() is stored in a statically allocated
structure, data was overwritten when a context switch occurred during
(or shortly after) the execution of localtime(), potentially resulting
in critical data corruption. BUG#7 and BUG#8 are likely related.
This patch converts all usages of localtime() with localtime_r(), which

Instead of calling type-specific duplication handlers and inserting
clones of the original items when pasting, save the generic day item and
remove the actual item from the linked list, so that it can be inserted
anywhere else later.
The cut/paste buffer is moved to the interaction unit, item-specific cut
operations are changed to remove the item from the linked list only
instead of copying and freeing it. An item is only freed if another item
is cut before the current cut/paste buffer is pasted. All paste
operations are changed and reinsert the actual item instead of creating
a clone.

Commit 4ff3bb9d introduced a new format for parsing durations, thus
allowing a larger string to be retrieved from user input.
However, the string used is still declared with the old length,
leading to crashes when compiling with stack-smashing protection
features (the default on Archlinux). Inputting a duration string of
more than 8 characters (such as "+1d11h11m") would crash calcurse with
a *** stack smashing detected *** message.
Using a larger string from the start fixes the bug.
