Work on negotiation Add helpers to convert between pinos and gstreamer formats. Use pinos formats in the API. Work on removing some hardcoded stuff and instead use the real format from the pinos server. Use memfd and sealing.

gst: Add support for DMA_DRM / explicit modifiers Gstreamer 1.24 added and largely switched to a new, modifier aware DMABuf API. Unfortunately that breaks the existing DMABuf support in the PW Gst element. Add support for the new API.

Remove dynamic types Do not use dynamic types anymore. The reason is that it's difficult: - to maintain a shared type database over a network. - the extra overhead when translating between processes and for maintaining the translation tables. - race conditions in translating in RT-threads, this is a problem because we want to make event streams. We now have simple enums with types and extension points for all types. This is also nicer to use in general. We don't need the mapper anymore or pass strings around as types. There is a parallel type info system to get more info about ids and enums and their hierarchy. It can also be used for debugging.

gst: Fix sanitization of non-writable caps `gst_caps_make_writable()` may create a copy which we have to keep using afterwards. The return value was meant to be used for that, but was promptly forgotten for the initial user. Avoid such errors in the future by using an in-out parameter instead. While on it, add a type check and remove a check for an impossible condition. Fixes: 8a271a87b ("gst: Sanitize caps before translating")

void gst_caps_sanitize (GstCaps **caps);
gst: Sanitize caps before translating DMABuf caps without concrete formats and modifiers don't map well to the Pipewire negotiation process. Introduce a new gst_caps_sanitize() helper function, where such cases can be handled.

gst: Add helper to fixate DMA_DRM caps When support for modifier-aware DMA_DRM formats was added in f1b75fc6, the translation between Pipewire parameters and Gstreamer caps was kept compatible with the] non-DMA_DRM/legacy API by reporting format/modifier combinations with linear or invalid modifier both as `format` and `drm-format`. In cases when a linear modifier ends up being negotiated, this, however, resurts in non-fixated caps, preventing the negotiation to succeed. Add a helper that allows to fixate such caps.
