André Marçais 3408bbcdda print help to stderr on usage error (#510)
`print_usage` is called in two cases:

1) when `-h` is given on the command line.
2) when there is a usage error.

In the first case, the help message should go to stdout. In the second case,
it is an error, and should go to stderr.

NRK 0620d473c2 allow {white,black}listing thumbnail cache dirs (#461)
this adds the cli flags --cache-{allow,deny} along with
corresponding config.h vars which allows the user to control
which directories will have thumbnail cache written.

this is a more general version of the `cache-whitelist` patch
that existed in the nsxiv-extra repo:

NRK 9b122c82fa add compiled features into --version output (#462)
a lot of application which allow selecting features at build time seem
to output the build config with `--version` or similar (e.g ffmpeg).

aside from giving the user information about the feature set the binary
was compiled with (in case the user didn't compile it themselves, e.g on
a binary distro) it can also (possibly) help when submitting bug
reports.

NRK 1f788a318b add cli flag --alpha-layer
now that we have long-opts, we don't have to worry about exhausting the
alphabet list for short-opts. so adding a cli flag to set/unset the
checker background makes sense.

NRK 85fffbb277 improve error message on bad cli argument (#371)
currently the error messages have the shortopt hardcoded in them, even
when the user actually entered a longopt:

	$ ./nsxiv --framerate v
	nsxiv: Invalid argument for option -A: v

and as far as I see, there's no way to *reliably* tell weather we're
processing a longopt or a shortopt. perhaps we can do some shenanigangs
with `optind` but that seems finicky at best.

and it seems like other coreutils which support longopt has similar issues:

	$ xargs --max-procs=z
	xargs: invalid number "z" for -P option

utils like `grep` and `head` seems to work-around it by not mentioning the flag:

	$ head --lines=z
	head: invalid number of lines: ‘z’
	$ grep --max-count=l
	grep: invalid max count

this patch does the same thing as `grep/head` and omits the flag from
the error message.

NRK daee34477a fix potential truncation of cli arguments (#367)
strtol() returns a `long`, but we're storing the result in an `int`
which might end up getting truncated. change `n` to `long` and guard
against >INT_MAX arguments in cases where it matters.

use a float for storing argument of `-S`

change `opt.slideshow` to `unsigned` similar to `img.ss.delay`

NRK 216f312578 add support for long-opts (#332)
Uses [optparse] to add support for long-opts. optparse is posix
compliant with getopt(3) and thus would be backwards compatible.
It does not have any dependency (not even the c standard library!) and
is C89 compatible and thus fits our current code-style.

[optparse]: https://github.com/skeeto/optparse

Note that we're using a couple `pragma`-s to silence some harmless
warnings. This should be portable because these pragma-s don't change the
behavior of the program. Furthermore, C standard mandates that unknown
pragma's should be ignored by the compiler and thus would not result in
build failure on compilers which do not recognize them.

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;
}
```
