wayland/surface: Make sure transactions are applied in consistent order If multiple transactions have entries for the same surface, they are applied in the same order as they were committed. Otherwise, they can be applied in any order. This is preparation for following changes, transactions are still applied as soon as they're committed. v2: * Move GQueue for transactions to MetaWaylandCompositor (Jonas Ådahl) v3 * Say "entry for" instead of "state for", since there can be transaction entries with no state (for surfaces which are getting destroyed). v4: * Use a hash table to keep track of all candidate transactions which might be newly ready to be applied. * Use clearer function / variable names. v5: * Use custom single-linked list instead of hash table for candidate transactions, ordered by the transaction commit sequence number, so that they're attempted to be applied in the same order as they were committed. * Rename transaction->queue to transaction->committed_queue, and simplify its handling. v6: (Carlos Garnacho) * Add spaces between type casts and values. * Use (gpointer *) instead of (void**). v7: (Jonas Ådahl) * Use G_MAXSIZE instead of ULONG_MAX. * Fix indentation of meta_wayland_transaction_apply & meta_wayland_transaction_maybe_apply_one parameters. * Refactor find_next_transaction_for_surface & ensure_next_candidate helper functions out of meta_wayland_transaction_apply. * Refactor has_unapplied_dependencies helper function out of meta_wayland_transaction_maybe_apply_one. * Make while (TRUE) loop in meta_wayland_transaction_maybe_apply consistent with general usage. * Drop unused value local from meta_wayland_transaction_commit. * Store pointer to compositor object in transactions, instead of pointer to the queue of committed transactions. * Drop tautological g_assert from meta_wayland_transaction_apply.
