libobs/nix: Move X11-specific code to obs-nix-x11.c

Currently, obs-nix.c is highly tied to the X11 display
server. It includes X11 headers directly, and make use
of X11 functions. Most of the code inside obs-nix.c that
is X11-specific is related to hotkeys handling.

Introduce a new vtable for hotkeys callbacks, that will
used by X11 and Wayland to expose their specific routines.
In this commit, only the X11 hotkeys vtable is implemented.

Move all the X11-specific code to obs-nix-x11.c, and add
a new function to retrieve the X11 hotkeys vtable.

+ * different values).
+ *
+ * Then there's a key code (xcb_keycode_t), which is basically an index to the
+ * actual key itself on the keyboard (e.g., '1' and '!' will share the same
+ * value).
+ *
+ * xcb_keysym_t values should be given to libobs, and libobs will translate it
+ * to an obs_key_t, and although xcb_keysym_t can differ ('!' vs '1'), it will
+ * get the obs_key_t value that represents the actual key pressed; in other
+ * words it will be based on the key code rather than the key symbol.  The same
+ * applies to checking key press states.

- *
- * First, there's a global key symbol enum (xcb_keysym_t) which has unique
- * values for all possible symbols keys can have (e.g., '1' and '!' are
- * different values).
- *
- * Then there's a key code (xcb_keycode_t), which is basically an index to the
- * actual key itself on the keyboard (e.g., '1' and '!' will share the same
- * value).
- *
- * xcb_keysym_t values should be given to libobs, and libobs will translate it
- * to an obs_key_t, and although xcb_keysym_t can differ ('!' vs '1'), it will
- * get the obs_key_t value that represents the actual key pressed; in other
- * words it will be based on the key code rather than the key symbol.  The same
- * applies to checking key press states.
