easier writing of unit tests and better error reporting.

The work on this is not 100% complete, but everything is present to
allow real-world testing of the code.  The only remaining major todo
item is to (hopefully!) enhance the handling of non-ASCII bytes in headers
converted to unicode by RFC2047 encoding them rather than replacing them with
'?'s.

verification for higher-level protocols.

.. instead of raising a fatal error. Even if the current directory was deleted,
use relative paths may still work (eg. run Python with "../python").

On Windows, Py_UNICODE is wchar_t, so we can avoid the expensive Py_UNICODE*
=> wchar_t* conversion.

 * Don't define _Py_wstat() on Windows, Windows has its own _wstat() function
   with a different API (the stat buffer has another type)
 * Include windows.h

I suppose that I reapplied my local patch creating Python/fileutils.c whereas
the file already existed.

 * _Py_fopen() and _Py_stat() come from Python/import.c
 * (_Py)_wrealpath() comes from Python/sysmodule.c
 * _Py_char2wchar(), _Py_wchar2char() and _Py_wfopen() come from Modules/main.c
 * (_Py)_wstat(), (_Py)_wgetcwd(), _Py_wreadlink() come from Modules/getpath.c

Use _Py_wchar2char() to support surrogate characters in the input path.

This undoes a previous attempt to fix some of the skips. Value and copy
come from sharedctypes rather than plain ctypes, and the test skipping is
then done at the class level rather than test-by-test.

There are zero skipped tests after the fix.

All unicode functions uses PyObject* except PyUnicode_AsWideChar(). Fix the
prototype for the new function PyUnicode_AsWideCharString().

 * Create format_arg variable to use the right types
 * Strip trailing spaces

 * fix argv0 reference counter if PyList_SetItem() fails
 * don't use complex if conditions, but a simple indentation and "goto error"
 * simplify error handling (remove Py_XDECREF(importer) from the error label)
 * don't set sys_path to NULL (it's useless, sys_path is a borrowed reference
   and sys_path is not a static variable)
 * try to write only one instruction per line for better readability

Create sys_update_path() static function. Do nothing if argc==0.

after the file is closed.  Patch by Jeffrey Finkelstein.

Fix the suspicious builder not to write CRLF, update suspicious file and add instructions to Makefile.
