8dd694b569 Simplify day storage
The function day_process_storage() is a wrapper for day_store_items().
It has an unused second argument, and is only used twice to load the
selected day. It has been removed.

A new function, get_slctd_day(), is the equivalant of get_today() and
replaces the very awkwardly named ui_calendar_get_slctd_day_sec().

4263a28504 DST fix: adjusting time in appointments
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.

f91b7cdee0 DST fix: adding appointments on the day when DST starts or stops
A new apppoint inserted on the day when the clock is adjusted backward by an
hour got a wrong start time (an hour late). Reason: mktime() must not use the
Daylight Saving Time information returned by localtime_r().

Also editorial simplifications.

fd635150a8 Start and end time validation.
All appointment times are checked for validity. Overflow by time
arithmetic is detected. End times are checked when appointments
are moved. Three functions are involved: parse_datetime(),
parse_duration() and parse_date_duration(); they all have a

bb7381765c Scrollbar and right window border (corrected)
When a scrollbar is on display in APP or TOD windows, the right
vertical border (outside the scrollbar) is not highlighted
when the window is selected.

The scrollbar is always highlighted:
- when APP or TOD is deselected
- in configuration windows where borders otherwise are not

The patch moves the scrollbar parameters (except highlight)
from arguments of draw_scrollbar() to the function itself.
The highlight argument was 1; instead it is set higher in
the call hierarchy (wins_update_panels()) and passed on down.

e733d09ea0 Default colour as foreground colour
In the default colour setup (white on black), white could only
with great difficulty be used as customized foreground colour,
because the colour pair COLR_CUSTOM then was identical to
COLR_DEFAULT (default on default). This made it impossible to
distinguish the selected element in lists.

The patch turns on the video attribute bold when default is chosen
as foreground colour.

691d6b33ee Check for the year span 1902-2037
Reintroduce year check for systems with a 32-bit time_t type. Remove the
lower limit (1902) for systems with a 64-bit time_t. This limits
movements in the calendar (for 32-bit systems) and in no way ensures
constistency of data.

Commit a12833e (Handle dates past January 19th, 2038, 2015-01-19)
removed the upper limit (2037) on dates but left the lower limit (1902).
It did not ensure the support of the target system.
