[issue11395] print(s) fails on Windows with long strings

[Santoso Wijaya]

Attached a modified patch that should work against 3.2+ heads:

- Added `isatty` bit field in isatty that's evaluated during its
  construction. This should eliminate the need to call `isatty()` on 
  every write.
- Cap buffer length to 32767 (4 * 1024 - 1) when writing to a tty.
- Test this by supplying `CREATE_NEW_CONSOLE` to `subprocess.call`, so 
  we do not flood regrtest's console output.

These changes are conditionally compiled on Windows only.

Should a similar patch be made for 2.7+ (maybe earlier)?
