(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.

object to Py_FileSystemDefaultEncoding with the "surrogateescape" error
handler, return a bytes object. If Py_FileSystemDefaultEncoding is not set,
fall back to UTF-8.
PyUnicode_DecodeFSDefault*() doesn't use surrogateescape error handler, and so
PyUnicode_FromEncodedObject(v, Py_FileSystemDefaultEncoding, "surrogateescape")
cannot be replaced by PyUnicode_DecodeFSDefault().
It's a bad idea to try to fix surrogates things in Python 3.1...

Create os.environb mapping and os.getenvb() function, os.unsetenv() encodes str
argument to the file system encoding with the surrogateescape error handler
(instead of utf8/strict) and accepts bytes, and posix.environ keys and values
are bytes.

On Windows, ctypes does no longer check the stack before and after
calling a foreign function. This allows to use the unmodified libffi
library.
Remove most files from _ctypes/libffi_msvc, only two include files
stay (updated from _ctypes/libffi/...). Other files are used in the
cross-platform _ctypes/libffi directory.

Fix test_undecodable_env of test_subproces for non-ASCII directory
This test was introduced by r80421 (issue #8391).
The fix: copy the environment variables instead of starting Python in an empty
environement. In an empty environment, the locale is C and Python uses ASCII
for the default file system encoding. The non-ASCII directory will be encoded
using surrogates, but Python3 is unable to load a module or package with a
filename using surrogates.
See issue #8242 for more information about running Python3 with a non-ascii
directory in an empty environement.
