(1) use a different algorithm that roughly halves the total number of
    multiplications required and results in more balanced multiplications
(2) use a lookup table for small arguments
(3) fast accumulation of products in C integer arithmetic rather than
    PyLong arithmetic when possible.

Typical speedup, from unscientific testing on a 64-bit laptop, is 4.5x
to 6.5x for arguments in the range 100 - 10000.

Patch by Daniel Stutzbach; extensive reviews by Alexander Belopolsky.

object to Py_FileSystemDefaultEncoding with the "surrogateescape" error
handler, return a bytes object. If Py_FileSystemDefaultEncoding is not set,
fall back to UTF-8.

error handler, not only the default error handler (strict)

failure. Set the file system encoding to utf-8 (instead of None) if getting
the locale encoding failed, or if nl_langinfo(CODESET) function is missing.

   error handler (and not "replace")
 * Remove "The function is intended to be used for paths and file names only

   other purposes than file names

  subprocess.Popen.__del__ referenced global objects, which is a no-no thanks to
  interpreter shutdown semantics. Same issue goes for the methods that __del__
  called. Now all the methods capture the global objects it needs as default
  values to private parameters (could have stuck them on the class object itself,
  but since the objects have nothing directly to do with the class that seemed
  wrong).

  There is no test as making one that works is hard. This patch was
  verified against a consistently failing test in Mercurial's test suite, though,
  so it has been tested in some regard.

  Closes issue #5099. Thanks to Mary Stern for the bug report and Gabriel
  Genellina for writing another patch for the same issue and attempting to write
  a test.

I've removed the hopeful note about a future higher-level module since
it's been in there for quite a long time and nothing of the sort has
come up. There are a few places where markup was added to cross-reference
other sections, and many of the external links have been removed and now
point to newly created sections containing previously undocumented
information.

The Value Types section was created and it's contents were taken from
a function-specific area, since it applies to more than just that
function. It fits in better with the other newly documented constants.
