Guido van Rossum 393661d15f Add warning mode for classic division, almost exactly as specified in 
PEP 238.  Changes:

- add a new flag variable Py_DivisionWarningFlag, declared in
  pydebug.h, defined in object.c, set in main.c, and used in
  {int,long,float,complex}object.c.  When this flag is set, the
  classic division operator issues a DeprecationWarning message.

- add a new API PyRun_SimpleStringFlags() to match
  PyRun_SimpleString().  The main() function calls this so that
  commands run with -c can also benefit from -Dnew.

- While I was at it, I changed the usage message in main() somewhat:
  alphabetized the options, split it in *four* parts to fit in under
  512 bytes (not that I still believe this is necessary -- doc strings
  elsewhere are much longer), and perhaps most visibly, don't display
  the full list of options on each command line error.  Instead, the
  full list is only displayed when -h is used, and otherwise a brief
  reminder of -h is displayed.  When -h is used, write to stdout so
  that you can do `python -h | more'.

Notes:

- I don't want to use the -W option to control whether the classic
  division warning is issued or not, because the machinery to decide
  whether to display the warning or not is very expensive (it involves
  calling into the warnings.py module).  You can use -Werror to turn
  the warnings into exceptions though.

- The -Dnew option doesn't select future division for all of the
  program -- only for the __main__ module.  I don't know if I'll ever
  change this -- it would require changes to the .pyc file magic
  number to do it right, and a more global notion of compiler flags.

- You can usefully combine -Dwarn and -Dnew: this gives the __main__
  module new division, and warns about classic division everywhere
  else.
