Move getstring() related stuff into a separate file as a first step on
our way to UTF-8 support for line editing helpers.

Add utf8_width() and utf8_strwidth() which can be used to calculate the
display width of a single character or a string, respectively. A lookup
table is used to spot double width characters, as well as composing
characters. There currently isn't any code to deal with ambigious
characters.

Use a global flag to record whether the terminal was resized instead of
redrawing everything each time a KEY_RESIZE is read.
Add some additional checks to help_write_pad() as invalid actions may be
passed now due to using signals instead of virtual key presses.

Rename "days" structure to "excp" which seems to be a better name here.
Use generic linked lists of excp structures instead of using the "days"
structure which again contains a linked list implementation. Do some
cleanups and invocation fixes.

Use them instead of "recur_apoint_list" and "next" pointers in
"recur_event" type variables. Includes some code simplifications and
cleanups.

To be used with llist_fn_match_t callbacks later.
I feel a bit ill adding those functions. This definitely is a hack.
Ultimately, there should be some generic recur_item_inday() function
that accepts both recurring apointments and events (or some wrapper
structure) instead of parameter galeere. This is not the right place to
fix that tho.

Add LLIST_TS_* macros in a fashion similar to the already existing
LLIST_* macros. Unlike the non-thread-safe version, these include
LLIST_TS_LOCK and LLIST_TS_UNLOCK which can be used to lock (and unlock)
a list (hence the thread-safety).

As discussed on the mailing lists, the various linked list
implementations we currently use at a dozen of different places in the
calcurse source tree are inconvenient and should be replaced by a single
generic solution.
This is a first approach to introduce such a generic implemetation. It
provides following functions:
* llist_init(): Initialize a list.
* llist_free_inner(): Loop through a list and free all items.
* llist_free(): Free the list itself (but not the individual items).
* llist_first(): Get the first item of a list.
* llist_nth(): Get the nth item of a list.
* llist_next(): Get the successor of a list item.
* llist_find_first(): Find an item using a callback function.
* llist_find_next(): Find the next match using a callback function.
* llist_find_nth(): Find the nth item in a list (using a callback).
* llist_get_data(): Get a pointer to the actual data of a list item.
* llist_add(): Add an item at the end of a list.
* llist_add_sorted(): Add an item to a sorted list (using a comparison
callback function).
* llist_remove(): Remove an item from a list.
Linked lists are stored in "llist_t" structures, list items are to be
stored in "llist_item_t" structs.
All of the llist_*() functions either expect a pointer to a llist_t
structure (in case the function operates on the list itself) or a
pointer to a llist_item_t (llist_*_next() and llist_get_data()).

Functions that never return should be declared "noreturn" to tell the
compiler this fact. Also, clang-analyzer will detect this attribute and
take it into account when running scan-build.

Keeping empty notes doesn't make sense here. Also, there doesn't seem to
be a simple way to erase notes yet. This will make calcurse delete any
notes that are empty (meaning that they are either 0-byte files or
contain nothing but a newline character) when returning from the editor.

date_sec2hour_str() is superseded by date_sec2date_str() with "%H:%M" as
date format string, so replace all invocations and remove that function

Short forms are only accepted in interactive mode (e.g. when using the
"Go to" function, editing a recurrent item's end date, and so on).
Samples: "1/1/30" for "01/01/2030", "26" for the 26th of the currently
selected month/year or "3/1" for Mar 01 (or Jan 03, depending on the
date format) of the currently selected year.
