When introducing the fmt_day_heading() function in commit d56cc7a (Make
heading in appointments panel configurable, 2017-08-19), we forgot to
initialize the dynamic string. This resulted in calling mem_free() with
a garbage pointer, potentially resulting in a segmentation fault. Fix
this by calling string_init() before using the string.

A new function keys_wgetch() reads full UTF-8 characters instead of
single ASCII characters only.
Key bindings for regular ASCII characters are stored in a hash map while
the actions of keys with higher code points are stored in a linked list
for space efficiency.
The key serialization methods are updated to handle UTF-8 characters as
well; extended UTF-8 characters (characters not in the ASCII range) are
serialized by using the hexadecimal representation of the corresponding
code points (e.g. "U+00E4").

In the appointments panel, an appointment has a '-' to mark the time
span, and the description on the following line is slightly indented.
When the appointment is changed into a recurrent one, the '-' is changed
to a '*', making it easily distinguishable but the description also gets
a '*', thus breaking the pattern. Drop the extra '*'.

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.

When adding a key already in use for another action, a warning box is
displayed. The text length is limited by the window width through the
use of strncpy(). If the limit is exceeded, the string will have no null
termination, resulting in unpredictable behaviour.
A similar problem in fatalbox() is fixed as well.

The pair_content() function can be used to retrieve a color pair. The
foreground and the background color numbers are written to addresses
specified by the second and third parameters. While both parameters were
optional in older ncurses implementations (making it possible to pass
NULL pointers if the one does not care about either foreground or
background color), recent implementations seem to assume that both
parameters are valid pointers. Thus, instead of passing NULL, we need to
pass a pointer to a dummy variable when we do not care about the
background color.
Partly fixes GitHub issue #31.

The recur_apoint_starts_before() filter function expected the second
parameter to be passed by value, whereas its only caller passed the

such that the parameter is passed by reference.
Also, add a comment to the only caller of recur_apoint_starts_before()

To prevent from illegal memory access, we checked whether the list of
todo items is empty before performing an interactive todo item action
such as flagging or removal. However, since 1a4bf2b (Add a "hide
completed" view to the todo panel, 2016-01-17), it is possible to hide
completed items from the todo panel. Thus, it may occur that the todo
list box is empty while the list of todo items is not.
To detect such situations as well, teach todo_get_item() to return NULL
if the requested item does not exist. Then, instead of checking whether
the todo item list is non-empty, make sure that the item returned by
todo_get_item() is non-NULL when performing an action.

current start time. If only a time is entered, the item is modified to
start on the current date and the new start time.

Starting the notification thread more than once can result in strange
behavior. For example, when launching external commands, only the most
recently started thread is stopped which results in the external
command's screen output being overwritten by the notification bar.
Currently, there are a couple of situations where the thread is started
twice. As a first countermeasure, explicitly check whether the thread is
already running (and terminate it) before starting a new one.
