    Take just one argument, the buffer.
    Make it current, and inhibit recursive GC.
    Access and update the undo list directly; return void.
    Refer to the undo...limit variables directly.
    Test undo_outer_limit only after counting the whole current command.
    When it's exceeded, call the function in undo-outer-limit-function.
    (undo_limit, undo_strong_limit, undo_outer_limit): Moved from alloc.c.
    (Vundo_outer_limit_function): New variable.
    (syms_of_undo): Define undo-limit, undo-strong-limit
    and undo-outer-limit here, and undo-outer-limit-function.
    Doc fixes.
