  Issue #7610: Reworked implementation of the internal
  :class:`zipfile.ZipExtFile` class used to represent files stored inside
  an archive.  The new implementation is significantly faster and can
  be wrapped in a :class:`io.BufferedReader` object for more speedups.
  It also solves an issue where interleaved calls to `read()` and
  `readline()` give wrong results.  Patch by Nir Aides.
