Fix broken ci and enable higher level optimization (#220)
* [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.

Add keybind to scroll to image center (#203)
There are keybinds for scrolling to the edges of an image but there's no way back to the center. This is particularly annoying while zooming.

make thumbnail bindings configureable via config.h (#167)
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.

fix: reset statusbar after failed keyhandler (#191)
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.

remove unused function and typedef (#199)
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.

fix: animation slowdown when zoomed in (#200)
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.

Allow setting cache size based on memory percentage (#184)
The problem:

1. For the most people imlib2's default 4MiB is unreasonably low;

2. Hardcoding cache size to ~256MiB has performance benefits and doesn't
   increase RAM usage too much on relatively modern systems;

3. But we can't do that, because that would be detrimental to low spec systems
   that (apparently) not (?) building nsxiv from source, as been discussed
   #171

Solution:

Calculate cache size based on total memory.

Default is set as 3%, which means:
* ~245MiB for 8GiB
* ~30MiB for 1GiB
* and so on

CACHE_SIZE_LIMIT (256MiB by default) sets the highest possible value. And in
case we cannot determine the total memory (e.g since _SC_PHYS_PAGES isn't
POSIX) use CACHE_SIZE_FALLBACK (32MiB by default) instead.

fix: broken compilation when using HAVE_LIBFONTS=0 (#194)
compilation currently fails with `make HAVE_LIBFONTS=0` due to
`EXIT_SUCCESS` not being defined. I assume Xft.h includes stdlib.h which
is why compilation works with HAVE_LIBFONTS=1

this switches to using 0 as cg_quit argument in keybindings. if my
interpretation of the C99 standard is correct, then 0 and EXIT_SUCCESS
means the same thing.

> If the value of status is zero or EXIT_SUCCESS, an
> implementation-defined form of the status successful termination is
> returned.

fix crash when zooming out on small images (#178)

NRK ca7368aa89 Revert "fix: out-of-bounds access when bg not in color map"
with this patch certain gif images will fail to play. one other problem
here is that it suddenly breaks the loop without free-ing data and rows,
leading to a memory leak.

regardless, this needs to be investigated further.

here's an example image where this happens:

N-R-K 0639047dde allow configuring imlib2's cache size (#171)
by default imlib2 uses a 4mb cache, which is quite small. this allows
users who have more memory to spare to set a bigger cache size and avoid
reloading an already viewed image if it fits into the cache.

with the exception of arrays, all other var names in config.h are in ALL

mark functions and vars as static (#146)
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;
}
```

NRK 2df33208d7 apply -0 to stdin/-i as well
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.
