gh-93820: Fix copy() regression in enum.Flag (GH-93876)
GH-26658 introduced a regression in copy / pickle protocol for combined
`enum.Flag`s. `copy.copy(re.A | re.I)` would fail with
`AttributeError: ASCII|IGNORECASE`.
`enum.Flag` now has a `__reduce_ex__()` method that reduces flags by
combined value, not by combined name.

test_asyncore: Optimize capture_server() (#93867)
Remove time.sleep(0.01) in test_asyncore capture_server(). The sleep
was redundant and inefficient, since the loop starts with
select.select() which also implements a sleep (poll for socket data
with a timeout).
run_until() of test.test_asyncio.utils now uses an exponential sleep
delay (max: 1 second), rather than a fixed delay of 1 ms. Similar
design than support.sleeping_retry() wait strategy that applies
exponential backoff.

Use support.sleeping_retry() and support.busy_retry() (#93848)
* Replace time.sleep(0.010) with sleeping_retry() to
use an exponential sleep.
* support.wait_process(): reuse sleeping_retry().
* _test_eintr: remove unused variables.
gh-79579: Improve DML query detection in sqlite3 (#93623)
The fix involves using pysqlite_check_remaining_sql(), not only to check
for multiple statements, but now also to strip leading comments and
whitespace from SQL statements, so we can improve DML query detection.
pysqlite_check_remaining_sql() is renamed lstrip_sql(), to more
accurately reflect its function, and hardened to handle more SQL comment
corner cases.

Classes ReferenceType, ProxyType and CallableProxyType have now correct

local reference to the os.remove() function. Patch by Victor Stinner.

gh-91317: Document that Path does not collapse initial `//` (GH-32193)
Documentation for `pathlib` says:
> Spurious slashes and single dots are collapsed, but double dots ('..') are not, since this would change the meaning of a path in the face of symbolic links:
However, it omits that initial double slashes also aren't collapsed.
Later, in documentation of `PurePath.drive`, `PurePath.root`, and `PurePath.name` it mentions UNC but:
- this abbreviation says nothing to a person who is unaware about existence of UNC (Wikipedia doesn't help either by [giving a disambiguation page](https://en.wikipedia.org/wiki/UNC))
- it shows up only if a person needs to use a specific property or decides to fully learn what the module provides.
