Christopher Faylor 6452eb1f2a * cygtls.cc (_cygtls::init_exception_handler): Semi-revert to making only
ourselves the exception handler and nothing else.
* exceptions.cc (open_stackdumpfile): Use correct format specifiers for unicode
when printing nameof stackdump file.
(stack_info::walk): Stop walking if ebp points into cygwin itself.
(_cygtls::handle_exceptions): Detect when signal is masked and treat as if it
