Convert quick_symbol_functions to use methods
This changes quick_symbol_functions to be a base class with pure virtual methods, rather than a struct holding function pointers. Then, objfile is changed to hold a unique_ptr to an instance of this class. struct psymbol_functions is put into psympriv.h, and not psymtab.c, because that is convenient later in the series. gdb/ChangeLog 2021-03-20 Tom Tromey <tom@tromey.com> * psympriv.h (struct psymbol_functions): New. * symfile.c (syms_from_objfile_1, reread_symbols): Update. * symfile-debug.c (objfile::find_compunit_symtab_by_address) (objfile::lookup_global_symbol_language): Update. * quick-symbol.h (struct quick_symbol_functions): Convert function pointers to methods.
