    (Ada) Cleanup code by using ada_is_access_to_unconstrained_array call.
    
    This patch just avoids code duplication by using a function we
    introduced recently (ada_is_access_to_unconstrained_array).
    
    gdb/ChangeLog:
    
        * ada-lang.c (ada_is_access_to_unconstrained_array): Remove static
        declaration.
        * ada-lang.h: add ada_is_access_to_unconstrained_array prototype.
        * ada-varobj.c (ada_varobj_get_number_of_children,
        ada_varobj_describe_child, ada_value_is_changeable_p): Cleanup code.
    
    Tested on x86_64-linux.
    No new testcase provided, as this is just a refactoring.
