Now that we're fully POSIX compliant and fixed up some minor issues with
ISO C99, use "-std=c99 -pedantic -D_POSIX_C_SOURCE=200809L" as default
build flags for calcurse and the test suite.

Extract iCal and pcal import/export routines into separate files. This
reduces complexity of the super huge "io.c" source file and makes it
easier to follow changes that affect the iCal and pcal routines only
(commits affecting both formats are very uncommon).
Before:
$ wc -l src/io.c
2938 src/io.c
After:
$ wc -l src/{io,ical,pcal}.c
1445 src/io.c
1263 src/ical.c
317 src/pcal.c

We used custom_load_conf() to load the configuration file and
io_save_conf() to save configuration. Move these functions, including
all helpers, to a central location.

Add an implementation of the SHA1 hash algorithm based on a public
domain project by Steve Reid <sreid@sea-to-sky.net>. You can get the
original sources from:
ftp://ftp.funet.fi/pub/crypt/hash/sha/sha1.c
We will need this for several things. File names of note files will be
generated based on a hash their content instead of using a random name.
Items can be uniquely identified using a hash.
In addition to the regular sha1_init(), sha1_update() and sha1_final()
operations, our implementation also contains wrappers for hashing a
string or a stream.

* Add new note_edit() and note_view() helper functions. Use these
instead of copy-pasted code in *_note_edit().
* Move all note-related functions (note_edit(), note_view(),
note_erase()) to a new source file "note.c".

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.

We forgot to add those to the "_SOURCES" variable in commit
0eb1da8dd7fa3ae9d95e12df6058fb41a5ec1c11 and
d668963e2056027526374098efe2869a0d389b92. Spotted by `make distcheck`.

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()).
