We could add two methods to BufferedIOBase:
- peek_inside(self[, n]): returns a view of up to n bytes on the internal buffer
- read_inside(self[, n]): same as peek_inside(), but also advances the file
position after the end of the returned view

The good thing is that default unoptimized versions of these methods could be
provided in the BufferedIOBase ABC, simply by calling peek() (resp. read()) and
wrapping the result in a memoryview.
