[issue35796] time.localtime returns error for negative values

[Mba]

New submission from Mba :

Steps to reproduce the bug:
```
>>> import sys
>>> sys.version
'3.6.7 (v3.6.7:6ec5cf24b7, Oct 20 2018, 13:35:33) [MSC v.1900 64 bit (AMD64)]'

>>> import datetime
>>> print(datetime.datetime.now().astimezone().tzinfo)
datetime.timezone(datetime.timedelta(0, 3600), 'Central European Standard Time')

>>> import time
>>> time.localtime(0)
time.struct_time(tm_year=1970, tm_mon=1, tm_mday=1, tm_hour=1, tm_min=0, 
tm_sec=0, tm_wday=3, tm_yday=1, tm_isdst=0)
>>> time.localtime(-1)
Traceback (most recent call last):
  File "", line 1, in 
OSError: [Errno 22] Invalid argument
```

On Ubuntu it works fine:
```
>>> time.localtime(-1)
time.struct_time(tm_year=1970, tm_mon=1, tm_mday=1, tm_hour=0, tm_min=59, 
tm_sec=59, tm_wday=3, tm_yday=1, tm_isdst=0)
```

[issue29619] st_ino (unsigned long long) is casted to long long in posixmodule.c:_pystat_fromstructstat

Mba added the comment:

> I don't think that a filesystem produce inodes larger than 2^63-1

The problem is real: the large inode number was assigned to a file created by 
MacOS on a share exported via CIFS, and then stated by Linux using NFS export.

New submission from Mba:

ino_t is of type 'unsigned long' or 'unsigned long long'. Casting it to signed 
type means that negative values are incorrectly returned for large inodes.
