441d30fac7 Issue #15989: Fix several occurrences of integer overflow 
when result of PyLong_AsLong() narrowed to int without checks.

This is a backport of changesets 13e2e44db99d and 525407d89277.

4fb8caee87 Issue #14850: Now a chamap decoder treates U+FFFE as "undefined mapping" 
in any mapping, not only in an unicode string.

20b654acb5 Issue #16455: On FreeBSD and Solaris, if the locale is C, the 
ASCII/surrogateescape codec is now used, instead of the locale encoding, to
decode the command line arguments. This change fixes inconsistencies with
os.fsencode() and os.fsdecode() because these operating systems announces an
ASCII locale encoding, whereas the ISO-8859-1 encoding is used in practice.

27cbcd6241 Fix the internals of our hash functions to used unsigned values during hash 
computation as the overflow behavior of signed integers is undefined.

In practice we require compiling everything with -fwrapv which forces overflow
to be defined as twos compliment but this keeps the code cleaner for checkers
or in the case where someone has compiled it without -fwrapv or their
compiler's equivalent.

Found by Clang trunk's Undefined Behavior Sanitizer (UBSan).

Cleanup only - no functionality or hash values change.

27b1ca29cc Issue #16416: On Mac OS X, operating system data are now always 
encoded/decoded to/from UTF-8/surrogateescape, instead of the locale encoding
(which may be ASCII if no locale environment variable is set), to avoid
inconsistencies with os.fsencode() and os.fsdecode() functions which are
already using UTF-8/surrogateescape.

83fe2e1c22 Issue #14783: Improve int() docstring and also str(), range(), and slice(). 
This commit rewrites the docstring for int() to incorporate the documentation
changes made in issue #16036.  It also switches the docstrings for int(),
str(), range(), and slice() to use multi-line signatures.

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.

63e6c3222f Consolidate the occurrances of the prime used as the multiplier when hashing 
to a single #define instead of having several copies in several files.

This excludes the Modules/ tree (datetime and expat both have a copy
for their own purposes with no need for it to be the same).
