NRK c131b1ed83 fix: -Wsign-compare warnings (#336)
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.

NRK 7c59cc7edc fix build failure due to missing <stdio.h> (#337)
the following combination currently fails to build:

	$ make HAVE_LIBFONTS=0 HAVE_LIBWEBP=1

this is probably because one of the font library was including <stdio.h>

NRK 5c3a796e55 [ci]: slience some clang-tidy warnings
the warnings on r_readdir(), img_load_gif() and strcpy seems to be false
positives. the warning about fmt being unused is valid, but not worth
fixing with additional #ifdef guards.

use `assert` to silence the false positive cases when possible,
otherwise use a NOLINT comment with an explanation.

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.

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:

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.

N-R-K c6275374b0
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;
}
```

fix: memory leak in img_load_webp (#135)
if `multi.cap` is >0 that means `multi.frames` has already been malloc-ed. by
unconditionally malloc-ing again, we're losing all the old memory.

this makes it so we're only malloc-ing (or realloc-ing) when needed.

Fix behaviour when TrueColor / 24 bit depth is not available (#114)
* 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

TAAPArthur 25a3114709 Rework the build system (#19)
* Added simple configure script

Added simple script to autodetect if optional dependencies are installed
and enable/disable them as needed. Note this solution uses the compiler
directly instead of an external program like pkgconfig so it doesn't
require any extra dependencies. It is intended to work with any
arbitrary compiler; it has been tested with tcc and gcc.

There are some "breaking" changes hidden here
- HAVE_GIFLIB was renamed to HAVE_LIBGIF to match HAVE_LIBEXIF
- Simply typing `make` will no longer try to build with optional
  dependencies

* use implicit RM variable

* General clean-up in configure

- Use printf instead of echo
- Format style

* honor env PREFIX, use LDLIBS

* Revert "General clean-up in configure"

This reverts commit 8683c179dbf273a330f9a224a4d481a7bea42c5f.

* honor env LDFLAGS if set

* Don't set OPTIONAL_LIBS in configure

* make OBJ all caps

* follow suckless style build system

- remove configure script.
- HAVE_LIBGIF and HAVE_LIBEXIF defaults back to 1
- unload several varibales onto config.mk
- make version all-caps
- add -O2 optimization
- use CPPFLAGS for includes and defines

* Revert "follow suckless style build system"

This reverts commit 8bf75b1f68d72df349edba8d998d4659dd956dd8.

* Generate config.mk from make

* Inlined configure in Makefile

* update docs

* cleanups

- changes to config.mk should trigger a rebuild
- remove potentially confusing variables form Makefile

* Use install instead of mkdir/cp/chmod when sensible

* fixup! Inlined configure in Makefile

* Don't generate config.mk on rm -f *.o sxiv

* update docs and cleanups

- make config.mk silent
- mention editing config.mk in README

* fallback to 0 if user edits config.mk in unexpected way

* add comment on config.mk

* remove invalid comment

configure script is removed

* slight restructure

- make version all caps
- restructure variables that users may want to edit to top
- use CPPFLAGS for defines
- add some comments
- remove needless echos since we have verbose output now

* add echos back
