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).

Overview of existing implementation
-----------------------------------
The APP panel displays the 'day_items' vector in the 'lb_apt' listbox. A
listbox consists of a scrollwin (structure) in which a number of items
is displayed. The listbox keeps track of:
- the number of items
- the selected item
- the type of each item in an array type[]
- the height of each item (ie. how many screen lines) in an array ch[]
- how to display an item (on the screen)
The latter three are handled by functions fn_type(), fn_height(),
fn_draw(). The first two are used to fill in the corresponding array
entry, type[] or ch[], for item number i, the third draws item number i.
The items are taken from the global variables
vector_t day_items
int day_items_nb
in day.c. Items include captions (DAY_HEADING, DAY_SEPARATOR).
Everything is sorted for display (DAY_HEADING, events, DAY_SEPARATOR,
appts). These are filled in ("stored") [by day_store_items() for the
selected day in the calendar], before being "loaded" into the listbox.
See do_storage() in calcurse.c and ui_day_item_add() in ui-day.c.
New APP panel design
--------------------
Several days are displayed in the APP panel by loading them with
day_store_items().
With several days come several headings and separators. DAY_SEPARATOR is
reinterpreted to separate days, and a new separator, EVNT_SEPARATOR,
separates events from appointments. To sort everything, an 'order'
member of type time_t is added to the day_item structure. It is set for
headings and separators as well as for appointments and events as
follows:
item order
---------------------
DAY_HEADING BGNOFDAY (= midnight)
EVNT_SEPARATOR BGNOFDAY
DAY_SEPARATOR ENDOFDAY
event start time (midnight)
appointment start time (first day)
BGNOFDAY (following days, if any)
The sort function day_cmp() (used by vector_sort) is extended to sort by
order first.
The order field always indicates the day to which an item belongs. This
comes in handy, because with several days in the APP panel it is
necessary to distinguish between the selected day in the calendar and
the selected day in the APP panel. This raises the question which day
should actions (commands) operate on: the one selected in the calendar
or the one selected in the APP panel? Unquestionably the one on the APP
panel which is the one tacitly implied. In most cases it is not a
problem, though, because actions work on the selected item and the
selected day does not come into play. But in some cases it does:
delete item When deleting an occurrence of a repeated item, the
selected day is the exception day to add.
view item day_popup_item() needs the day of the selected item
for display of correct start/end times.
cut/paste item Paste needs the selected day in which to paste.
add item The day of the new item is taken from the calendar.
Instead a dummy event is inserted in an empty day.
This makes the day selectable, which is otherwise
impossible with only the DAY_HEADING displayed. The
dummy event is selectable but cannot be edited or
deleted (but viewed or piped).
With more than one day in the day_items vecter, an appointment spanning
more than one day may occur more than once in the vector (with start/end
times suitably adjusted for display). A day_item is no longer (always)
identified by the aptev_ptr (item) value. Instead the combination
(order, item.<ptr>) is used; order is roughly the day.

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?

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
is thread-safe.

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.
