(_cygtls::andreas): Convert to a pointer. (san): Convert to a real class with methods. Use a linked list to keep track of previous handlers on the "stack". (myfault): Rewrite to use new san class rather than calling directly into _cygtls. * cygtls.cc (_cygtls::init_exception_handler): Just assume that we're always using the standard exception handler. (_cygtls::init_thread): Reflect loss of argument to init_exception_handler. * dcrt0.cc (dll_crt0_1): Ditto. * dfcn.cc (dlopen): Ditto. (dlclose): Reset the exception handler after FreeLibrary. * dll_init.cc (dll_list::detach): Make sure that the exception handler is initialized before calling destructors. * exceptions.cc (_cygtls::handle_exceptions): Accommodate new andreas pointer. * thread.cc (verifyable_object_isvalid): Pass objectptr to faulted for explicit NULL pointer checking. * tlsoffsets.h: Regenerate.
