    PR11671 Allocate __stp_tf_vma_entry dynamically.

    Get rid of TASK_FINDER_VMA_ENTRY_ITEMS and __stp_tf_vma_free_list_items
    array list completely. All __stp_tf_vma_entry are allocated dynamically
    now. This is possible since stap_add_vma_map_info() is only called
    through the task_finder from a user context.

    There is no more fixed maximum number of VMA pages that will be tracked
    at runtime. This reduces memory use for those scripts that don't need any,
    or only limited target process VMA tracking and allows easier system
    wide probes inspecting shared library variables and/or user backtraces.
    stap will now silently ignore -DTASK_FINDER_VMA_ENTRY_ITEMS.

Plus some follow up commits to fix some corner cases (3dde67, 972ea1 and
7fbefb)
