this moves all the build variables intended to be modified by the user
over to `config.mk` similar to other suckless software.
also move CPPFLAGS down below for cosmetic purposes.
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.
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
long's, whatever the size of long may be.

not all WMs support `_NET_WM_NAME` and `_NET_WM_ICON_NAME`
this patch sets `WM_NAME` and `WM_ICON_NAME` inside win_set_title()

remove some non-posix extensions which slipped through and adjust ci to
new Makefile changes
users can still overwrite the variables explicitly by using
`make VAR=VALUE`
packagers can also add extra libs to LDLIBS, we're internally using
NSXIV_LDLIBS now.
* [ci] fix broken ci
* [ci] enable higher optimization level and lto
higher optimization levels enable more warnings and deeper analysis.
likewise, lto can catch a couple errors which typically goes unnoticed
without it.
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.
byteorder_t and size_readable is not used anywhere within the code.
byteorder_t seems to be a remain from some time sxiv handled exif data itself instead of relying on a library, introduced in 691c6d7, and probably became irrelevant when libexif was added as dependency again. And size_readable from some time it displayed the file size in the window title, introduced in bad9a70.
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.
