[Python-ideas] Replace time_t by Py_time_t

In the thread "datetime module enhancements" Guido and others said that
it is unpythonic to limit timestamp (seconds since Epoch) to an signed
int with 32bit.


I've made a patch that introduces a new type Py_time_t as a first step
to increase the size of time stamps. For now it's just an alias for time_t.

  typedef time_t Py_time_t;

I'm proposing to change time_t in two steps:

Python 2.6:
Replace every occurrence of time_t by Py_time_t and give third party
authors time to change their software

Python 2.7 / 3000:
Change Py_time_t to a signed 64bit int on all platforms and provide the
necessary workaround for platforms with a 32bit time_t.
