tokens with embedded whitespace, such as C++ demangled names.
* defs.h (demangle_and_match, strcmp_iw, skip_quoted): Prototypes.
* main.c (gdb_completer_quote_characters): Add global variable.
* main.c (symbol_completion_function): Total rewrite for C++
demangled name handling.
* main.c (skip_quoted): New function.
* main.c (main): Set rl_completer_quote_characters.
* symmisc.c (dump_symtab): Print source language for symtab.
* symtab.c (expensive_mangler): Add prototype and function.
* symtab.c (completion_list_add_symbol): Total rewrite for new
C++ demangled name handling.
* symtab.c (lookup_symbol): Check for demangled C++ symbol first,
other changes for demangled C++ symbol handling.
* symtab.c (lookup_demangled_block_symbol): Use demangle_and_match.
* symtab.c (lookup_demangled_partial_symbol): Use demangle_and_match.
* symtab.c (decode_line_1): Recognize C++ demangled names on input.
* symtab.c (completion_list_add_symbol): Total rewrite for new
C++ demangled name handling.
* symtab.c (expensive_mangler): New function.
* utils.c (strcmp_iw, demangle_and_match): New functions.
* xcoffread.c (aixcoff_symfile_read): Fix prototype.
* All GDB files that #include defs.h: Removed stdio.h.
(defs.h): #include stdio.h.
This has been tested by building GDBs for all targets hosted on Sun4.
None of the build problems were related to stdio.h inclusion. (n.b.
many configurations don't build for other reasons.)
