Replace "..." quoting with `...` quoting in output, to avoid slosh-escaping the
common double-quote character (") in log output.
Introduce alloca_str_toprint() function that produces an entire null-terminated
string in printable form.
Change various toprint strbuf helper functions to take two optional quote chars
instead of one mandatory.
