In some cases, fullpath value is used whereas fullpath was not always
initialized. Warning found by the Clang Static Analyzer.

struct guarantees the loop will always be run once to initialize code.

to be able to unload the module.

 - Use Unicode for module paths and names, self->archive and self->prefix
 - Format module names and paths use %R instead of '%U' to escape surrogate
   characters (PEP 383)
 - Use PyImport_ExecCodeModuleObject() instead of PyImport_ExecCodeModuleEx()
 - Use PyImport_AddModuleObject() instead of PyImport_AddModule()

zipimport uses ASCII encoding instead of cp497 to decode filenames, at
bootstrap, if the codec registry is not ready yet. It is still possible to have
non-ASCII filenames using the Unicode flag (UTF-8 encoding) for file entries in
the ZIP file.

PyErr_Format() and PyUnicode_FromFormat() are able to allocate the right buffer
size and to catch memory allocation failures.

UTF-8 is just fine for module names.

I cannot use %U: fullname is a bytes object, not an unicode object. %A format
cannot be used, it adds 'b' (bytes) prefix. So create cant_find_module()
function to decode the filename and raise the error message.

Use PyUnicode_FSConverter to support surrogates in the full name.

Don't hardcode path size in make_filename().

instead of utf-8.

the unicode flag, to decode the filename, instead of the filesystem encoding.
Use the same choice than the zipfile module.

... instead of a char*. Encode the module path to the fileystem encoding
(for PyImport_ExecCodeModuleEx) instead of utf-8.

PyImport_AddModule() returns a borrowed reference. Don't display "import ... #
loaded from Zip ..." on error.

It occurs if the path contains surrogates.

zipimport is now able to load a module with an unencodable filename.

  Issue #6697: use %U format instead of _PyUnicode_AsString(), because
  _PyUnicode_AsString() was not checked for error (NULL).

  The unicode string is no more truncated to 200 or 400 *bytes*.
