screen: remove unneeded vlc_module.h include

We don't use module_need() or "video blending".

glblend: use the regular video filter callback setter

So it matches the same Open callback as the other video filters.

video_filter/opengl: set the priority to 0

All video filters have a priority of 0 because they are loaded by name and
should never be picked as a fallback for other filters.

This video filter is either loaded by name from the command-line or
in vlc_gl_WrapOpenGLFilter().

vlc_filter: use a single type to open all types of filters

Because of the filter chain, they must have a common way to open them.

Some types of filters may not be used by the filter chain (for example the text
renderer). But still need to be activated the same way. If this ever changes
They will need their own open callback type back.

filter: add a function to load filters

The activate function should match exactly vlc_filter_open, rather than use
a generic vlc_object_t loader. Then we don't have any dirty cast.

The code is similar to module_need, with better typing.

It's not possible to inline this because we need to call vlc_objres_clear()
for each module loaded unsuccessfully. It's not a public API.

vlc_filter: add a function to unload a filter module

As well as an inline function to completely destroy a filter_t.

The close function is called and the deactivate is not, since there should be none.

use vlc_filter_UnloadModule instead of multiple local calls

It's better suited for filter_t.

includes: update warning

Only the first 3 elements are the same in filter_t and decoder_t.

This warning is probably wrong anyway.

filter_chain: expand vlc_module_load() locally

So we don't need an activate function with varargs. We can call the vlc_filter_open directly.
