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.

since Imlib2 v1.7.5, it is capable of parsing exif data on jpeg files
and auto orienting them. this caused nsxiv to rotate the image twice.
Closes: https://github.com/nsxiv/nsxiv/issues/187
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.

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.

* specifies the function argument type in commands.h compared to leaving
it unspecified. all the functions in cmd_t must have arg_t as it's
argument.
* changes to commands.h will now trigger a rebuild - this restores old
behavior prior to 12efa0e
* cg_quit now uses it's argument as exit status
* DestroyNotify invokes cg_quit rather than calling exit directly.
* Explicitly pass EXIT_SUCCESS to cgquit in keybinding

now that imlib2 (v1.7.5) is able to load the first frame of an
animated-webp file, we no longer need the `is_webp` check to bypass
imlib2.

This reverts commit 7e049d55d94f5c003d90e1a10187356f6a7f54b2.
When rendering images, destination image width and height may become
zero due to float-to-int conversion after zoom calculation, later
crashing when creating an image using those dimensions. This sets
a minimum of 1 to both variables.
Closes#82
* fix: send implicit_mod to process_bindings
this solves the edge case where someone might have `ShiftMask + A` in
their keybindings compared to a plain `A`.

* code-style: smuggle small style fix in
win_draw_bar now mimics autoreload_nop.c functions
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:
https://i.postimg.cc/SQf1TJJg/awoo-study.gif
This reverts commit cca7834e67.
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
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`.

with this change `-0` is turned into a more generic switch which can be
used to send NULL-separated file-list to the key-handler as well.
this also means `-0` no longer implicitly enables `-o`
Closes: https://github.com/nsxiv/nsxiv/issues/140
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.

this code snippet was introduced in
2703809a23
but does not seem to be needed.
from what i can tell this is some sort of hack that might've been needed
back when we didn't bypass imlib2 when loading webp.
Ctrl-Button1 now has a relative drag using the XC_fleur cursor.
XC_fleur is normally the cursor for "size all" action, which has 4
arrows pointing to 4 directions.
