Python calling into a subinterpreter).

the Solaris issue is solved.

But add assertion on the maximum character in various encoders: UTF-7, UTF-8,
wide character (wchar_t*, Py_UNICODE*), unicode-escape, raw-unicode-escape.

Fix also unicode_encode_ucs1() for backslashreplace error handler: Python is
now always "wide".

 * Replace PyUnicode_FromUnicode(NULL, 0) by PyUnicode_New(0, 0)
 * Replce PyUnicode_FromUnicode(str, len) by PyUnicode_FromWideChar(str, len)
 * Replace Py_UNICODE by wchar_t
 * posix_putenv() uses PyUnicode_FromFormat() to create the string, instead
   of PyUnicode_FromUnicode() + _snwprintf()

 * Add tests for PyUnicode_EncodeDecimal() and PyUnicode_TransformDecimalToASCII()
 * Remove the unused "e" variable in replace()

 * unicode_ready() has a simpler API
 * try to reuse unicode_empty and latin1_char singleton everywhere
 * Fix a reference leak in _PyUnicode_TranslateCharmap()
 * PyUnicode_InternInPlace() doesn't try to get a singleton anymore, to avoid
   having to handle a failure

It tests indirectly PyUnicode_Copy(): ensure that the string is a copy.
