gh-91231: Add shutdown_timeout to multiprocessing BaseManager (#32112) 
Add an optional keyword 'shutdown_timeout' parameter to the
multiprocessing.BaseManager constructor. Kill the process if
terminate() takes longer than the timeout.

Multiprocessing tests pass test.support.SHORT_TIMEOUT
to BaseManager.shutdown_timeout.

bpo-45735: Promise the long-time truth that `args=list` works (GH-30982) 
For threads, and for multiprocessing, it's always been the case that ``args=list`` works fine when passed to ``Process()`` or ``Thread()``, and such code is common in the wild. But, according to the docs, only a tuple can be used. This brings the docs into synch with reality.

Doc changes by Charlie Zhao.

bpo-45554: Document multiprocessing.Process.exitcode values (GH-30142) 
This addresses [bpo-45554]() by expanding the `exitcode` documentation to also describe what `exitcode` will be in cases of normal termination, `sys.exit()` called, and on uncaught exceptions.

No issue associated with this PR.
Should be backported in 3.7 and 3.8.

bpo-35491: Enhance multiprocessing.BaseProcess.__repr__() (GH-11138) 
* Add the pid and parent pid to multiprocessing.BaseProcess.__repr__().
* Add negative sign (ex: "-SIGTERM") to exitcode (process killed
  by a signal)
* Only call _popen.poll() once.

Example:
  <ForkProcess(ForkPoolWorker-1, started daemon)>
becomes:
  <ForkProcess name='ForkPoolWorker-1' pid=12449 parent=12448 started daemon>

Example:
  <ForkProcess(ForkPoolWorker-1, stopped[SIGTERM] daemon)>
becomes:
  <ForkProcess name='ForkPoolWorker-1' pid=12960 parent=12959 stopped exitcode=-SIGTERM daemon>

Replace KB unit with KiB (#4293) 
kB (*kilo* byte) unit means 1000 bytes, whereas KiB ("kibibyte")
means 1024 bytes. KB was misused: replace kB or KB with KiB when
appropriate.

Same change for MB and GB which become MiB and GiB.

Change the output of Tools/iobench/iobench.py.

Round also the size of the documentation from 5.5 MB to 5 MiB.

Jelle Zijlstra 1e5d54cfa0 bpo-31965: fix doc for multiprocessing.connection.Client and Listener (#4304) 
* fix doc for multiprocessing.connection.Client

The authenticate argument does not exist on either Client or Listener:
- https://github.com/python/cpython/blob/master/Lib/multiprocessing/connection.py#L483 (master)
- https://github.com/python/cpython/blob/3.6/Lib/multiprocessing/connection.py#L478 (3.6)
- https://github.com/python/cpython/blob/3.5/Lib/multiprocessing/connection.py#L478 (3.5)
- https://github.com/python/cpython/blob/3.4/Lib/multiprocessing/connection.py#L487 (3.4)
The documentation also claimed that these functions will call `current_process().auth_key`, for which I could find no evidence in the code. I rewrote the documentation to reflect the actual behavior.

Also made some small changes to vary sentence structure.
