    [API CHANGE] tdf#150683 a11y: Switch a11y child index to 64 bit
    
    With 16k column support in Calc enabled by default in
    
        commit 4c5f8ccf0a2320432b8fe91add1dcadf54d9fd58
        Date:   Tue Mar 8 12:44:49 2022 +0100
    
            change default Calc number of columns to 16384 (tdf#50916)
    
    , the number of Calc cells in a spreadsheet is larger than
    SAL_MAX_INT32, meaning that a 32-bit a11y child index is no more
    enough and using it resulted in integer overflows in
    methods handling corresponding Calc cells in the a11y layer.
    This e.g. had the effect of the Orca and NVDA screen readers
    not announcing focused or selected cells properly when their
    a11y child index was out of the 32-bit integer range.
    
    Switch the internal a11y child indices to 64 bit to
    be able to handle this properly internally.
    
    Since the platform APIs (at least AT-SPI on Linux and
    IAccessible2 on Windows; from what I can see LO's macOS
    a11y bridge doesn't directly expose the child index)
    are still restricted to 32 bit, larger child indices
    still cannot be exposed via the platform APIs.
    
    As a consequence, use of the the IAccessible2 and
    AT-SPI methods that use the child index remains
    problematic in those cases where the child index
    is larger. However, as an alternative to using the
    AT-SPI Table interface and the IAccessibleTable/
    IAccessibleTable2 interfaces with the child index
    to retrieve information about a specific cell,
    both AT-SPI and IAccessible2 also provide interfaces
    to retrieve that information directly
    from the cell object (TableCell interface for AT-SPI,
    IAccessibleTableCell for IAccessible2).
    
    Those interfaces are already implemented/exposed
    for winaccessibility (s. `CAccTable`) and the
    qt5/qt6/kf5 VCL plugins (s. the `QAccessibleTableCellInterface`
    methods implemented in `QtAccessibleInterface`).
    With the switch to 64-bit internal a11y child indices,
    these now behave correctly for cells with a child
    index that doesn't fit into 32 bit as well.
    
    NVDA on Windows already uses the IAccessibleTableCell
    interface and thus announcing focused cells works fine
    with this change in place.
    
    Orca on Linux currently doesn't make use of the AT-SPI
    TableCell interface yet, but with a suggested change to
    do so [1], announcement of selected cells works
    with the qt6 VCL plugin with a current qtbase dev branch
    as well - when combined with the suggested changes
    to implement support for the AT-SPI TableCell interface
    in Qt [2] [3] and the LO change based on that [4] and
    a fix for a nullptr dereference [5].
    
    The gtk3 VCL plugin doesn't expose the AT-SPI
    TableCell interface yet, but once it does so
    (via `AtkTableCell`), it also works with the
    suggested Orca change [1] in place.
    (Adding that is planned for an upcoming change,
    works with a local WIP patch.)
    
    For handling return values that are larger than what
    platform APIs support, the following approach has
    been chosen for now:
    
    1) When the return value is for the count of
    (selected) children, the maximum value N
    supported by the platform API is returned.
    (This is what `ScAccessibleTableBase::getAccessibleChildCount`
    did previously.)
    The first N elements can be accessed by their
    actual (selection) indices.
    
    2) When the return value is the child/cell index,
    -2 is returned for objects whose index is greater
    than the maximum value supported by the platform
    API.
    Using a non-negative value would mean that the
    index would refer to *another* actually existing
    child. A child index of -1 on the other hand
    tends to be interpreted as "child is invalid" or
    "object isn't actually a child of its (previous)
    parent any more)". For the Orca case, this would
    result in objects with a child index of -1
    not being announced, as they are considered
    "zombies" [6].
    
    What's still somewhat problematic is the case where
    more than 2^31 children are *selected*, since access
    to those children still happens by the index into
    the selection in the platform APIs, and not all
    selected items are accessible this way.
    (Screen readers usually just retrieve
    the first and last element from the selection and
    announce those.)
    
    Orca already seems to apply different handling for the
    case for fully selected rows and columns, so
    "All cells selected" or "Columns ... to ... selected"
    is announced just fine even if more than 2^31
    cells are selected.
    
    (Side note: While Microsoft User Interface
    Automation - UIA - also uses 32-bit indices, it also
    has specific methods in the ISelectionProvider2
    interface that allow to explicitly retrieve the
    first and last selected item,
    `ISelectionProvider2::get_FirstSelectedItem` and
    `ISelectionProvider2::get_LastSelectedItem`, but
    we currently don't support UIA on Windows.)
    
    Bound checks at the beginning of the methods from the
    `XAccessibleContext`, `XAccessibleSelection` and
    `XAccessibleTable` interfaces that take a child index
    (or in helper methods called by those) should generally
    already prevent too large indices from being passed to
    the methods in the lower layer code that take smaller
    integer types. Such bound checking has been
    been added in various places where it wasn't present yet.
    If there any remaining issues of this
    kind that show after this commit, they can probably be
    solved in a similar way (s.e.g. the change to
    `AccessibleBrowseBox::getAccessibleChild` in this
    commit).
    A few asserts were also added at
    places where my understanding is that values shouldn't
    be larger than what is supported by a called method
    anyway.
    
    A test case will be added in a following change.
