Allow multi-level classdef package. * lex.h (octave_base_lexer::fq_identifier_contains_keyword, octave_base_lexer::handle_fq_identifier, octave_base_lexer::enable_fq_identifier): New methods. * lex.ll (octave_base_lexer::fq_identifier_contains_keyword, octave_base_lexer::handle_fq_identifier, octave_base_lexer::enable_fq_identifier): Likewise. (FQ_IDENT_START, FQIDENT): New exclusive start condition and regex to handle fully-qualified identifier. (superclass reference rule, metaclass query rule): Use FQIDENT. (octave_base_lexer::handle_superclass_identifier, octave_base_lexer::handle_meta_identifier): Don't split package name. * parse.h (octave_base_parser::make_superclass_ref, octave_base_parser::make_meta_class_query): Remove package_nm argument. * pt-classdef.h (tree_classdef_superclass::id, tree_classdef_superclass::pkg): Removed members, replaced by cls_name. (tree_classdef_superclass::~tree_classdef_superclass): Remove deletion of removed members. (tree_classdef_superclass::cls_name): New member. (tree_classdef_superclass::tree_classdef_superclass): Initialize it. (tree_classdef_superclass::ident, tree_classdef_superclass::package): Removed methods. (tree_classdef_superclass::class_name): New method. * token.h (token::meta_name_token): Remove enum value. (token(int, std::string, std::string, std::string, int, int)): Remove constructor. (token::superclass_package_name, token::meta_package_name, token::meta_class_name): Remove methods. (token::sc::package_nm, token::mc): Remove union members. * token.cc (token(int, std::string, std::string, std::string, int, int)): Remove constructor. (token::~token): Remove case of meta_name_token. (token::superclass_package_name, token::meta_package_name, token::meta_class_name): Remove methods. * oct-parse.in.yy (FQ_IDENT): New terminal. (superclass_identifier): Adapt to changes in class token and class octave_base_parser. (meta_identifier): Likewise. (superclass_list): Add mid-rule to enable fully-qualified identifier. (superclass): Use FQ_IDENT. (octave_base_parser::make_superclass_ref, octave_base_parser::make_meta_class_query): Remove package_nm argument. * ov-classdef.cc (octave_classdef_superclass_ref::do_multi_index_op): Adapt to removal of package_nm argument. (F__meta_class_query__): Likewise. (cdef_class::make_meta_class): Adapt to changes in class tree_classdef_superclass.
