fix debug info code not being freestanding compatible

in stack tracing code, the idea was to detect the tty settings at the
top of the stack and pass the information down. somewhere along the way
this got changed so that setTtyColor was assuming the global stderr_file
was related to the output stream the stack trace was being printed to.

now, tty_color is changed to tty_config, and it is an enum rather than a
bool, telling how tty colors are expected to be handled. windows is
still incorrectly looking at stderr_file.
