Georg Brandl 09a7c72cad Merge from 3.1: Issue #13703: add a way to randomize the hash values of basic types (str, bytes, datetime)
in order to make algorithmic complexity attacks on (e.g.) web apps much more complicated.

The environment variable PYTHONHASHSEED and the new command line flag -R control this
behavior.

Victor Stinner c39211f51e Issue #9630: Redecode filenames when setting the filesystem encoding
Redecode the filenames of:

 - all modules: __file__ and __path__ attributes
 - all code objects: co_filename attribute
 - sys.path
 - sys.meta_path
 - sys.executable
 - sys.path_importer_cache (keys)

Keep weak references to all code objects until initfsencoding() is called, to
be able to redecode co_filename attribute of all code objects.

  Issue #789290: make sure that hash(2**63) == hash(2.**63) on 64-bit
  platforms.  The previous code was fragile, depending on the twin
  accidents that:

    (1) in C, casting the double value 2.**63 to long returns the integer
        value -2**63, and
    (2) in Python, hash(-2**63) == hash(2**63).

  There's already a test for this in test_hash.
