All keys known by ncurses can be bound. Thus the check for not
recognized keys in custom_keys_config() becomes superfluous.

All key names for ordinary ASCII keys as well as for escape keys (pseudo
keys) are cached in a lookup-table, keynames[], at startup. Mapping
between key names (strings) and key codes (integers) in keys_str2int and
keys_int2str) is performed through this table.
The key names used are those returned by the keyname() function of
ncurses. But to accommodate some of the names to the three-letter space
available in the status menu, four ordinary keys and the most common
escape keys have calcurse abbreviated names: ESC, TAB, RET, SPC and LFT,
HOM, PgU, INS, F1, etc.
All keys known by ncurses can be bound. Thus the check for not
recognized keys in the key configuration menu becomes superfluous. The
only keys that cannot be bound, are those escape keys not known to
ncurses, i.e. not described by the terminfo database for the terminal
type in use.

Code point mapping adjusted for multibyte characters to avoid the
ncurses range 0-KEY_MAX.
This includes three fixes:
1) test sequence in keys_assign_binding(),
2) reassemble multi-byte character in keys_wgetch(),
3) check for already in use in keys_assign_binding().
Rearrangement of code. The introduction of allocated memory in
keys_int2str() has as a consequence that check for recognized ncurses
pseudo characters now are in two places: keys_str2int() and
custom_keys_config(). The latter was moved from keys_wgetch() to improve
user information.
More informative warning messages in custom_keys_config().

The week number in the calendar panel is calculated according to
ISO 8601. Hence, Monday is the first day of the week and the
week number changes from Sunday to Monday.
However, calcurse ties the week number not to Monday, but to the
first day of the week as configured for display. Thus, when Sunday
is shown as first day of the week, the week number is correct for
Sunday, but wrong for the rest of the week (one behind).
With this patch the week number always follows the mon-sun week as
required by ISO 8601. A side effect is that when Sunday is displayed
as first day of the week, and Sunday is the selected day, the week
number displayed is invalid for the rest of the week (but changes
to the correct one when the selected day moves forward).
This raises the question whether the week numbering scheme should
follow the "first day of the week" choice and use the American week
numbering scheme instead of ISO 8601 when Sunday is the first day
of the week. But that is for the future.

Add a script to iterate over a certain date range, performing operations
on each of the dates and printing the result. An additional string can
be appended to each of the printed lines.
The script can be used to create "extended recurrent events". For
example
./calcurse-dateutil.py --date 2017-01-01 --range 365 --unique \
--append ' [1] Test event' bom next-weekday 3 skip-days 14
can be used to print an event for each third Thursday of each month in
2017.

This will allow much more flexibility and less code duplication when
adding OAuth2 support. OAuth2 support will require this library as it is
a dependency of oauth2client. The documentation was updated to reflect
the new dependency.

Instead of bailing out early in the build process when neither a version
file nor a valid Git repository is detected, use a hardcoded default
version string. This fixes building from shallow clones or Git
snapshots.
Also fixes GitHub issue #22.

Replace the save mutex with a common mutex, which is locked whenever
read or write operations on the data files are performed. Also, since
this mutex is an implementation detail, mark the locking functions
static and remove them from the header file.

Instead of blindly reloading data in io_reload_data(), compare the

and only reload if any of the hashes differs.

Move the check to compare the stored hashes of the data files with the

When reading the data files, compute a cryptographic hash of the file
contents and store it. When saving the files later, ensure that the hash
still matches the current file contents. If it does not, show a warning

Using the file name extension .sav and naming the variables "backup" is

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 '*'.
