The integer part of the timestamp can be rounded up, while the millisecond
calculation truncates, causing the log timestamp to be wrong by up to 999 ms
(affected roughly 1 in 8 million timestamps).
The list lookups become a big burden for very long lists.
This patch changes the "happy flow" path of 2 lookups into 1 lookup.

* bpo-42644: Validate values in logging.disable()
Technically make the value of manager a property that checks and convert
values assigned to it properly. This has the side effect of making
`logging.disable` also accept strings representing the various level of
warnings.
We want to validate the type of the disable attribute at assignment
time, as it is later compared to other levels when emitting warnings and
would generate a `TypeError: '>=' not supported between ....` in a
different part of the code base, which can make it difficult to track
down.
When assigned an incorrect value; it will raise a TypeError when the
wrong type, or ValueError if an invalid str.

The logging.FileHandler class now keeps a reference to the builtin
open() function to be able to open or reopen the file during Python
finalization.
Fix errors like:
Exception ignored in: (...)
Traceback (most recent call last):
(...)
File ".../logging/__init__.py", line 1463, in error
File ".../logging/__init__.py", line 1577, in _log
File ".../logging/__init__.py", line 1587, in handle
File ".../logging/__init__.py", line 1649, in callHandlers
File ".../logging/__init__.py", line 948, in handle

NameError: name 'open' is not defined
The 'extra' argument is not always used by custom logger adapters. For
example:
```python
class IndentAdapter(logging.LoggerAdapter):
def process(self, msg, kwargs):
indent = kwargs.pop(indent, 1)
return ' ' * indent + msg, kwargs
```
It is cleaner and friendlier to default the 'extra' argument to None
instead of either forcing the subclasses of LoggerAdapter to pass a None
value directly or to override the constructor.
This change is backward compatible because existing calls to
`LoggerAdapter.__init__` are already passing a value for the second
argument.

Fix a hang at fork in the logging module: the new private
_at_fork_reinit() method is now used to reinitialize locks at fork in
the child process.
The createLock() method is no longer used at fork.
* bpo-37742: Return the root logger when logging.getLogger('root') is called.
* Added type check guard on logger name in logging.getLogger() and refined a test.
Instead of attempting to acquire and release them all across fork
which was leading to deadlocks in some applications that had chained
their own handlers while holding multiple locks.
