- Add code in the spec file to modify the patch file
reduce-meson-dependency.patch (used to build in SLE/Leap) so that
we don't need to rebase it manually for every version update.
- Use gcc 11 in SLE/Leap since gcc 9 fails to build 0.3.75 with
../spa/include/spa/utils/cleanup.h:52:13: error: dereferencing pointer to incomplete type ‘DIR’ {aka ‘struct __dirstream’}

potential portal managed screencast nodes to link to the
camera even though it was not assigned permissions to do so
by the session manager.
- Permissions for links between nodes are now enforced. The
link will now check that the owner clients of the nodes can
see each other before allowing the link. This avoids
screensharing clients to accidentally being linked to the
camera nodes by the session manager. A side effect is that
patchbay tools will no longer be able to link portal managed
screencast nodes to the camera, for this we need a new
permission for those patchbay clients.
- The stream.rules/filter.rules are now evaluated when
connecting the stream/filter so that more properties can be
matched.
- Move some internal events from the context to the nodes to
better handle per-node threads in the future.
- Atomic operation macros were move from internal pipewire API
to public API.
SPA_VIDEO_FLAG_MODIFIER_FIXATION_REQUIRED flag to instruct
the application to fixate the modifiers. This simplifies some
logic in applications a lot.
