Introduce an internal API for dealing with linux sync files, and use it in the codebase to replace ad-hoc sync file management. The linux_sync_file_is_valid function is not currently used, but will be utilized in upcoming commits to implement the zwp_linux_explicit_synchronization_unstable_v1 protocol. Changes in v5: - Meson support. Changes in v3: - Use parameter name in function documentation. - Move kernel UAPI to separate header file. Changes in v2: - Add function documentation - Remove linux_sync_file_wait() Signed-off-by: Alexandros Frantzis <alexandros.frantzis@collabora.com>
