### Description
Enables hot-reloading of dwl; meaning almost all logic can be changed at runtime.
This obviously requires some black magic so for now there's a glibc 2.0 or later
dependency to this.
In particular this allows for every option in config.h to be changed at runtime.

#### Reloading
To reload rebuild dwl.so, perhaps reinstall it and then run trigger reload function (bound to Mod+Shift+R by default).
This currently calls `notify-send` in order to inform you of a reloading taking place.
So in short:
1. make changes to `config.h` or `dwl.c`
2. run `make` to rebuild dwl.so
3. run `sudo make install` to reinstall dwl


#### Limitations
Reloading the compositor will replace all functionality except for `main`, `setup`, `run` and the reload logic.
Note that you're responsible yourself for reloading ressources like fonts, which may only get acquired once.
A lot of components of dwl will also only get run on a trigger (the tiling for example).
So not every change will be immediate.

#### Notes
##### reduce compile errors
This patch triggers `-Wpedantic` a bunch (I don't think there's a way around this, `dlsym` yields `void*` pointers to functions).
This will show a lot of warnings but cause no errors.
So you may want to disable this compile option in order to get readable compiler output.
##### runtime dependencies
This does depend on you having a notification daemon like `dunst` or `mako` running as well as
having `notify-send` installed in order for the compositor to inform you of the reload.

#### How?
Most of all dwl functionality is moved into a shared object file `dwl.so`, which can be reloaded at runtime.
