* Move print_notefile() from "src/args.c" to "src/utils.c".
* Add a "%N" format specifier to print_*(). This invokes
print_notefile() and prints the content of an item's note file.

everywhere.

Add print_recur_apoint() and print_recur_event() helper functions to

these are only wrapper functions to print_apoint() and print_event()

Add a flexible helper function print_event() and use it whenever we

A small style fix that removes all remaining "(void)" casts. Using these

Use one of the following functions where appropriate:
* puts() (whenever we print hard coded strings to stdout)
* fputs() (whenever we print hard coded strings to a stream)
* putchar() (whenever we print a single character to stdout)
* fputc() (whenever we print a single character to a stream)
* strncpy() (whenever we copy hard coded strings to a buffer)
This removes the overhead introduced by the format string parser and
reduces the number of false positive C-format strings spotted by
xgettext(1)'s heuristics.

Rename recur_*_inday() to recur_*_find_occurrence() and use the new
functions whenever we actually care about the start time of an
occurrence.
Reintroduce recur_*_inday() as wrappers to recur_*_find_occurrence() and
pass NULL as start time buffer (which means "skip start time
calculation"). Keep using these when we only want to know if a recurrent
item belongs to a specific day but do not care about the actual start
time.

Completely rewrite our inday algorithm in recur_item_inday() and be more
fine-grained. This version can deal with recurrent multi-day
appointments unless they overlap.
In case of overlapping appointments, only the last appointment that
starts before the current day is shown. We will need to rewrite the
whole recur_item_inday() interface in order to fix this - this
relatively trivial patch is only the first step.

Make use of these new helpers at various places. Note that this patch
implies a few behavioural changes:
* Short forms such as "23:" and ":45" are allowed when entering times.
* Durations always need to be prefixed with a plus sign ("+"), with the
nice side effect that you can now use "+3:30" to declare an
appointment that lasts three hours and thirty minutes (that's much
more convenient than "+210").
Signed-off-by: Lukas Fleischer <calcurse@cryptocrack.de>
These helpers can be used in a fashion similar to parse_date(). In
addition to check_time(), parse_time() and parse_duration() support
short forms such as "23:" (instead of "23:00") and ":45" (instead of
"00:45").

Add a global count buffer to our main loop and pass it to keys_getch()
as well as to all motion commands.
This enables some fancy shortcuts:

* Type "4k" (or "28l") to move forward four weeks.
* Type "2$" to go to the end of next week.

In contrast to LLIST_{,TS}_FIND_FOREACH, these convenience macros search
for the first match and return successors until there is an item that
isn't matched by the filter callback. Any items beyond the first cut-off
are discarded.
Should be used when results are known to be continuous, such as
appointments and events belonging to a specific day etc.

Adding a tail pointer to each list increases memory footprint by four
bytes, while reducing the runtime of llist_add() from O(n) to O(1). In
testing, the time required to append 100000 elements to a linked list
was reduced from 29.245s to 0.009s.
Our second main concern is to reduce the runtime of llist_add_sorted()
when inserting elements from a presorted list (this is reduced from O(n)
to O(1) as well), since the data files contain appointments in sorted
order and are always processed front to back.
Some local numbers show how this speeds up calcurse startup (test set
with 50000 appointments):
0.22user 0.12system 0:00.35elapsed 99%CPU (0avgtext+0avgdata 5396maxresident)k
0inputs+8outputs (0major+1398minor)pagefaults 0swaps
As opposed to the unpatched binary:

0inputs+48outputs (0major+1396minor)pagefaults 0swaps
This is a ~10000% increase in speed. Timings for reading random input
files generated by a script stay the same (32.391s vs. 31.776s).

Now that we use hashes to identify notes, a garbage collector comes in
handy. We search for note files that aren't referenced anywhere. Such
files might come up if a note, that isn't connected with any other item,
is edited.

layout and the way our hash table implementation works.
