* run_key_handler: make the logic easier to follow
* remove timeout_t
the typedef is not needed. inline the declaration similar to the other
static structs.
* simplify estrdup
reuse emalloc, instead of calling malloc and null-checking.
* win_clear: initialize `e` right away
* process_bindings: explicitly check against NULL
most pointer checks in the codebase do explicit check.
* use a named constant instead of magic number
also changes the padding from 3 to 4 bytes according to [0]. but i
couldn't find any situtation where this mattered, so perhaps the current
padding is enough. but doesn't hurt adding one more byte.

mixing signed and unsigned types in comparison can end up having
unintended results. for example:
if (-1 < 1U)
printf("true\n");
else
printf("false\n");
previously we silenced these warnings, instead just fix them properly
via necessary casting, and in cases where the value cannot be negative
(e.g width/height members) make them unsigned.

currently, in case of an empty xresources we would fail to init:
nsxiv: Error allocating color ''
instead, just reject empty value and use the fallback.

utf8_decode() may return an errors, in which case the returned codepoint
might be garbage. the issue can be tested by adding the following to
`image-info` which produces invalid utf8 sequences:
base64 -d << EOF
9JCAgPSQgIH0kICC9JCAg/SQgIT0kICF9JCAhvSQgIf0kICI9JCAifSQgIr0kICL9JCAjPSQgI30

gJz0kICd9JCAnvSQgJ8=
EOF
on my system, this leads to the statusbar being filled with empty boxes.
check for returned error and skip the iteration.

* includes are sorted alphabetically
* their grouping and layout is the following:
- nsxiv.h will be the first include
- followed by any internal headers (e.g "commands.h" "config.h")
- followed by system headers (<stdlib.h> etc)
- followed by third party headers (X.h libwebp etc)
* also add `llvm-include-order` check to clang-tidy so that it can catch
unsorted includes during CI.

instead of dancing around with some `init` parameter, directly give
`win_set_title()` what it needs. `get_win_title()` now also does *just*
what the name says.
this simplifies things quite a bit and the functions now do what their
name implies more closely instead of doing some `init` dance internally.

just use a static buffer since the size is constant and doesn't change.
as opposed to using malloc, this also sets the buffer's initial memory
region to 0 by default.
also remove BAR_{L,R}_LEN from nsxiv.h, not needed after commit b4268fbf38d1f8433c73999466e116e68c7f81e7

currently we immediately close the font on win_init_font(), which was
introduced in 0d8dcfd. this was probably not correct since we use `font`
later in win_draw_text().
instead, the font should be closed at exit/cleanup.

Instead of effectively first mapping the window at regular size and then
fullscreening it, tell the WM to map the window at fullscreen size by
setting _NET_WM_STATE_FULLSCREEN before mapping the window.

The property _NET_WM_PID is a CARDINAL which per definition has format
32, whatever the size of pid_t may be.
CARDINALS (and other format 32 items) must always be passed to Xlib in

the goal here to mark functions and variables not used outside the
translation unit as static. main reason for this is cleanliness. however
as a side-effect this can help compilers optimize better as it now has
guarantee that a certain function won't be called outside of that
translation unit.
one other side-effect of this is that accessing these vars/function from
config.h is now different.
if one wants to access a static var/func from different translation unit
in config.h, he would have to create a wrapper function under the right
ifdef. for static functions one would also need to forward declare it.
here's a dummy example of accessing the function `run_key_handler` from
config.h under _MAPPINGS_CONFIG
```
static void run_key_handler(const char *, unsigned);
bool send_with_ctrl(arg_t key) {
run_key_handler(XKeysymToString(key), ControlMask);
return false;
}
```

Adds a set of config vars to control window fg/bg, bar fg/bg, mark
color and bar font. This allows everything that can be done from
.Xresources to be configurable from config.h.

* Fix regression introduced in c7ca547 which made nsxiv not start in
non-TrueColor X server.
* Introduce a new fix for embedding into tabbed-alpha.
* Fixes a visual glitch from original sxiv when drawing transparent images in 8
bit depth. In 8 bit PseudoColor, `.pixel` is just an index into the 256
defined colors and thus trying to extract rgb bits from it would result in
visual glitch. The values `.color.red` on the other hand and so on are always
integers between 0 and 0xFFFF representing the color as expected.
* Use XColor for win_bg/fg and mrk_fg

libXft and libfontconfig are now optional dependencies which can be
disabled via `HAVE_LIBFONTS=0`. Disabling them means disabling the
statusbar. This also does not search for freetype2 header if disabled.

currently the code-base doesn't make use of variable length array
despite being -std=c99. it was irresponsible of me to introduce VLA in
here.
since this function will be called quite often, i did not want to make
calls to malloc and free as they have some overhead.
512 should be sufficient enough and probably is far bigger than any
window title bar can display anyways.

since we're already allowing both window and bar colors to be
customizable, it doesn't make sense to not allow so for mark color.

* Fix font memory leak.
This memory leak has always been present in sxiv.

* Fix in tabbed with alpha patch

When the window is mapped, some ICCCM WM_HINTS are set.
The input field is set to true and state is set to NormalState.
To quote the spec, "The input field is used to communicate to the window
manager the input focus model used by the client" and "[c]lients with
the Passive and Locally Active models should set the input flag to
True". sxiv falls under the Passive Input model, since it expects keyboard
input, but only listens for key events on its single, top-level window instead
of subordinate windows (Locally Active) or the root window (Globally Active).
From the end users prospective, all EWMH/ICCCM compliant WMs (especially
the minimalistic ones) will allow the user to focus sxiv, which will
allow sxiv to receive key events. If the input field is not set, WMs are
allowed to assume that sxiv doesn't require focus.
