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.
`TextIOWrapper.__init__()` called `os.device_encoding(file.fileno())` if fileno is 0-2 and encoding=None.
But it is very rarely works, and never documented behavior.

Limit the maximum capturing group to 2**30-1 on 64-bit platforms
(it was 2**31-1). No change on 32-bit platforms (2**28-1).
It allows to reduce the size of SRE(match_context):
- On 32 bit platform: 36 bytes, no change. (msvc2022)
- On 64 bit platform: 72 bytes -> 56 bytes. (msvc2022/gcc9.4)
which leads to increasing the depth of backtracking.
No work has been done to move this forward. On the theory that perfect is the enemy of good, I'm going to push it and we can make minor edits as needed afterwards.
* Transform opcodes into opnames
* Print the whole stack at each opcode, and eliminate prtrace output at each (push/pop/stackadj)
* Display info about the function at each resume_frame
* Fix test_concurrent_futures to actually test what it says.
Many ProcessPoolExecutor based tests were ignoring the mp_context
and using the default instead. This meant we lacked proper test
coverage of all of them.
Also removes the old _prime_executor() worker delay seeding code
as it appears to have no point and causes 20-30 seconds extra
latency on this already long test. It also interfered with some
of the refactoring to fix the above to not needlessly create their
own executor when setUp has already created an appropriate one.
* Don't import the name from multiprocessing directly to avoid confusion.

- document that you cannot open a blob handle in a WITHOUT ROWID table
- document the blobopen() positional arguments in the same order as they
appear
- relocate sqlite3.Blob section
