PyLong_FromSsize_t was incorrect when sizeof(size_t) > sizeof(long);

rewrite it so that it doesn't care about relative sizes of size_t,
long and long long.

The rewrite is modeled on PyLong_FromLong, instead of using
PyLong_FromByteArray;  this makes the algorithm simpler and
more direct, and possibly also slightly faster.

 - Issue #2221: Corrected a SystemError "error return without exception set",
   when the code executed by exec() raises an exception, and sys.stdout.flush()
   also raises an error.
