Move TeX symbol decoding into the lexer (bug #39831).
* libinterp/Makefile.am (BUILT_SOURCES): Add corefcn/oct-tex-symbols.cc.
(BUILT_DISTFILES): Add corefcn/oct-tex-lexer.ll and
corefcn/oct-tex-symbols.cc.
(EXTRA_DIST): Add corefcn/oct-tex-lexer.in.ll and
corefcn/oct-tex-symbols.in.
(ULT_DIST_SRC): Filter out corefcn/oct-tex-lexer.ll from DIST_SRC and
add corefcn/oct-tex-lexer.in.ll instead.
(CLEAN_FILES): Add corefcn/oct-tex-parser.output.
* libinterp/corefcn/modules.mk (corefcn/oct-tex-lexer.ll,
corefcn/oct-tex-symbols.cc): New rules to build the TeX lexer.
(corefcn/txt-eng.cc): Add dependency on corefcn/oct-tex-symbols.cc.
* libinterp/corefcn/oct-tex-lexer.in.ll: Renamed from oct-tex.lexer.ll.
Remove COMMAND state. Remove ID regex. Replace rules for symbols with
tag @SYMBOL_RULES@.
* libinterp/corefcn/oct-tex-parser.yy (ID, CMD, identifier): Remove
tokens.
(SYM, sym): New token and value.
(symbol_element): Build from SYM.
* libinterp/corefcn/oct-tex-symbols.in: New file with supported TeX
symbols and corresponding codes (unicode and MS symbols).
* libinterp/corefcn/txt-eng.h (class text_element_symbol): Make it
inherit from text_element.
(text_element_symbol::code): Removed member.
(text_element_symbol::symbol): New member.
(text_element_symbol::text_element_symbol): Adapt constructor.
(text_element_symbol::get_symbol): New method.
(text_element_symbol::get_symbol_code): Make const.
* libinterp/corefcn/txt-eng.cc (symbol_names, symbol_codes): Remove
static variables, now auto-generated from oct-tex-symbols.in.
(oct-tex-symbols.cc): New include.
(text_element_symbol::get_symbol_code): Change implementation to simply
index into auto-generated symbol_codes array.
* libinterp/corefcn/txt-eng-ft.cc
(ft_render::visit(text_element_symbol)): Don't use
text_element_symbol::string_value(), use
text_element_symbol::get_symbol() instead.
