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.
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.

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).
* Specify the default encoding: write 'utf-8' instead of
sys.getdefaultencoding(), because the default encoding is now constant
* Specify the default errors value
