* ada-lang.h (ada_renaming_category): New enumerated type.

        (ada_lookup_encoded_symbol): Declare.
        (ada_parse_renaming): Declare.
        (ada_renaming_type,ada_is_object_renaming)
        (ada_simple_renamed_entity): Delete declarations.
        * ada-lang.c (ada_parse_renaming): New function to concentrate
        extraction of information from renaming symbols.
        (parse_old_style_renaming): New function to concentrate
        extraction of old-style (purely type-based) renaming information.
        (renaming_is_visible): Rename to...
        (old_renaming_is_invisible): Rename and change sense of
        renaming_is_visible.
        (remove_out_of_scope_renamings): Rename to...
        (remove_irrelevant_renamings): Renames remove_out_of_scope_renamings
        and augments with additional logic to handle cases where the same
        object renaming is encoded both as a reference variable and an
        encoded renaming.
        (ada_renaming_type,ada_is_object_renaming)
        (ada_simple_renamed_entity): Delete definitions.
        (ada_lookup_encoded_symbol): New function factored out of
        ada_lookup_symbol.
        (ada_lookup_symbol): Reimplement to call ada_lookup_encoded_symbol.
        (wild_match): Don't reject perfect match of prefix.
        (ada_find_renaming_symbol): Factor old-style renaming logic into
        find_old_style_renaming_symbol.
        (find_old_style_renaming_symbol): New name for content of old
        ada_find_renaming_symbol.
        (ada_prefer_type): Reimplement not to use ada_renaming_type.
        * ada-exp.y (write_object_renaming): Change interface.  Reimplement
        to use new arguments and ada_parse_renaming.
        Correct blocks used to find array index.
        (write_var_or_type): Reimplement to use ada_parse_renaming.
