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.

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
to the user and ask whether she wants to execute the merge tool.

Using the file name extension .sav and naming the variables "backup" is
slightly misleading, since the affected files actually contain the

When introducing the fmt_day_heading() function in commit d56cc7a (Make
heading in appointments panel configurable, 2017-08-19), we forgot to

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 '*'.

In the expected output, the punctual appointment (lasting one second in
the iCal data) was missing. The test was not failing because calcurse
did not print the missing item due to a bug. This bug was fixed by

making the test case fail. Fix the test case as well such that
everything behaves as expected again.

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.

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.
