Serhiy Storchaka 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.

Chris Jerdonek 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.

  Refactor some longobject internals:  PyLong_AsDouble and _PyLong_AsScaledDouble
  (the latter renamed to _PyLong_Frexp) now use the same core code.  The
  exponent produced by _PyLong_Frexp now has type Py_ssize_t instead of the
  previously used int, and no longer needs scaling by PyLong_SHIFT.  This
  frees the math module from having to know anything about the PyLong
  implementation.  This closes issue #5576.

  Style/consistency/nano-optimization nit:  replace occurrences of
    (high_bits << PyLong_SHIFT) + low_bits with
    (high_bits << PyLong_SHIFT) | low_bits
  in Objects/longobject.c.  Motivation:
   - shouldn't unnecessarily mix bit ops with arithmetic ops (style)
   - this pattern should be spelt the same way thoughout (consistency)
   - it's very very very slightly faster: no need to worry about
     carries to the high digit (nano-optimization).
