padding is enough. but doesn't hurt adding one more byte.

the current code is quite hacky and complex as it mixes multiple pointers. all
of this complexity is unnecessary. drop it by introducing an explicit scratch
buffer instead of implicitly abusing `arl->filename` as one. this also reduces
some unnecessary allocation overhead.
additionally, the argument to arl_setup must be the result of `realpath(3)` (as
commented in `nsxiv.h`). instead of commenting it, assert it.
and lastly, rename `arl_setup` to `arl_add` since it's not doing any "setup"
but rather *adding* a file to watch.

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.

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.
rather than calling the script unconditionally per redraw, we now have
a `title_dirty` flag and keep track of when any of the relavent
information changes.

currently the way check_timeout() is implemented, animate has higher
priority than slideshow. so if doing a redraw takes longer than the
frame delay of the animated image then it's going to continuously keep
animating and never reliably get to slideshow.
this issue can occur if the animated image has too fast of a delay or if
nsxiv is being run on a slow system where doing redraw takes too long.
the issue can be emulated by artificially slowing down img_render by
sticking a sleep in there.

to reproduce:
1. have an image-info script
2. invoke the key-handler
3. cancle invocation by pressing `escape`
at this point, the statusbar ends up being empty.
the regression seems to be caused by 6922d5d (changing select to poll),
unsure why that is.
in any case, this simplifies read_info quite a bit and solves the
regression as well. in short:
* read straight into the statusbar buffer
* if read succeeds, make sure buffer is null terminated and replace any
newline with space
* close the script
this happens when the keyhandler is invoked while viewing an animated
image. if {image,thumb}-info scripts exists, everything works as
expected. but if they don't, then update_info will override the
statusbar.
before we were using select, which expected `struct timeval` as
arg. so we needed to do ms -> timeval conversions.
but now since we're using poll, which accepts milisec as arg, there's
no need to do ms -> timeval -> ms. instead have check_timeouts directly
return ms.
with a couple exceptions as they cause too many -Wshadow warnings.
also moves the `extcmd_t` typedef on top for cosmetic purposes.
also enable `-Wmissing-prototypes` in the ci
usage of select (3) in modern programs is typically discouraged.
this simply replaces the select call with poll (3) instead.
and since poll conveniently ignores negative fds, this also reduces
needs for some special casing.
this also handles error if they occur, while old implementation didn't.
other than the error handling, no change in functionality should occur.
this allows for configuring thumbnail mode mouse bindings similar to
image mode bindings.
however we can't put the thumbnails bindings into the existing buttons[]
array due to fallthrough. For example M3 would switch mode and then end
up selecting an image.
which is why thumbnail bindings have been put into it's own array
`buttons_tns[]` and `buttons[]` has been renamed to `buttons_img[]` for
consistency.

fixes all -Wshadow related warnings (on gcc). this would allow us to use
`-Wshadow` in github workflow (https://github.com/nsxiv/nsxiv/pull/195).
i've thought about adding `-Wshadow` to our Makefile as well, but
decided against it to keep the Makefile CFLAGS barebore/minimal.
currently if the keyhandler invocation fails, for example due to it not
being present, the statusbar does not reset and stays on "getting
keyhandler input" message.
now the return value from run_key_handler() is used to determine if the
function was successful or not. and if the function failed, we call
handle_key_handler() with false which resets the statusbar.
we also no longer call redraw() within run_key_handler() and instead assign
it's return value to dirty which does a redraw if true.
rendering is a pretty expensive operation, especially when scaling with
anti-aliasing. by waiting for the image to render before setting
timeout, the actual timeout ends up being (render time + actual delay).
this pretty much fixes the slowdown entirely on all the images i've
tested. it should also improve things noticeably even in cases where
the delay between frames is shorter than how fast we can render.
although on such images, the issue may not be fixed entirely.

* code-style: smuggle small style fix in
win_draw_bar now mimics autoreload_nop.c functions
with the exception of arrays, all other var names in config.h are in ALL
CAPS. since keyhandler_abort is an unreleased feature, it should be okay
to rename it for consistency.
though.. in the future we should be more careful about naming when
adding new vars to config.h (or the codebase in general.)
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;
}
```
while i was initially against this since it can be done via `xargs -0`.
the problem with this approach is that there's a limit to how many args
a command can recieve, leading to problem like this [0] when opening
large (1k~) amount of images.
there's no limit on how big stdin can be, so being able to read a
null-separated list from stdin doesn't have this problem.

this allows users to configure navigation width from config.h. it also
allows disabling the navigation function entirely by using a 0 width.
one extra functionality this adds is being able to define an absolute
width (in pixels) instead of just percentage via `NAV_IS_REL`.

Before all the predated commands where kept in an array and their
indexes were used in bindings. This meant that users couldn't add their
own functions from the config file. Now key/mouse bindings have been
changed to to store the function ptr (wrapped in a cmd_t struct to also
store the mode) directly instead.
General cleanup done in this commit:
Defined `MODE_ALL` instead of using magic number.
For example, suppose one had bindings like:
{ 0, XK_q, g_quit, None },
{ ShitMask, XK_q, {quit_err}, None }
{ ControlMask, XK_q, {quit_err, .mode=MODE_IMAGE}, None }
The existing binding `q` has been left unchanged and is defined the same
way. However, the new hypothetical binding `Shift-q` can be used to call
the custom function quit_err in any mode (default). `Ctrl-q` on the
other hand will be called only on image mode.
Closes#50
Previously, the value of imgcursor was determined by where a pointer
binding was set to a ci_cursor_navigate. If it was then the pointer
would change to left/right arrows depending on the position relative to
the window. Now the user has full control of over it which also allows
them to preserve the behavior in case they wrap the function.
