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.
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()

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.
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;
}
```
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`

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.

Before all the predated commands where kept in an array and their
indexes were used in bindings. This meant that users couldn't add their
own functions from the config file. Now key/mouse bindings have been
changed to to store the function ptr (wrapped in a cmd_t struct to also
store the mode) directly instead.
General cleanup done in this commit:
Defined `MODE_ALL` instead of using magic number.
For example, suppose one had bindings like:
{ 0, XK_q, g_quit, None },
{ ShitMask, XK_q, {quit_err}, None }
{ ControlMask, XK_q, {quit_err, .mode=MODE_IMAGE}, None }
The existing binding `q` has been left unchanged and is defined the same
way. However, the new hypothetical binding `Shift-q` can be used to call
the custom function quit_err in any mode (default). `Ctrl-q` on the
other hand will be called only on image mode.
Closes#50
* 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

libXft and libfontconfig are now optional dependencies which can be
disabled via `HAVE_LIBFONTS=0`. Disabling them means disabling the
statusbar. This also does not search for freetype2 header if disabled.

* add -0 for outputting null-terminated list
this doesn't add much, if any, additional complexity to the codebase and
can be quite handy for scripting purposes.
