[3.10] bpo-42972: Track sqlite3 statement objects (GH-26475) (GH-26515) 
Allocate and track statement objects in pysqlite_statement_create.

By allocating and tracking creation of statement object in
pysqlite_statement_create(), the caller does not need to worry about GC
syncronization, and eliminates the possibility of getting a badly
created object. All related fault handling is moved to
pysqlite_statement_create().

Fix compiler warning for misleading guarding in the tkinter (GH-26244) (GH-26251) 
The newest gcc emmits this warning:

```
/Modules/_tkinter.c:272:9: warning: this ‘if’ clause does not guard... [-Wmisleading-indentation]
  272 |         if(tcl_lock)PyThread_acquire_lock(tcl_lock, 1); tcl_tstate = tstate; }
      |         ^~
/Modules/_tkinter.c:2869:5: note: in expansion of macro ‘LEAVE_PYTHON’
 2869 |     LEAVE_PYTHON
      |     ^~~~~~~~~~~~
/Modules/_tkinter.c:243:5: note: ...this statement, but the latter is misleadingly indented as if it were guarded by the ‘if’
  243 |     (*(PyThreadState**)Tcl_GetThreadData(&state_key, sizeof(PyThreadState*)))
      |     ^
/Modules/_tkinter.c:272:57: note: in expansion of macro ‘tcl_tstate’
  272 |         if(tcl_lock)PyThread_acquire_lock(tcl_lock, 1); tcl_tstate = tstate; }
      |                                                         ^~~~~~~~~~
/Modules/_tkinter.c:2869:5: note: in expansion of macro ‘LEAVE_PYTHON’
 2869 |     LEAVE_PYTHON

```

that's because the macro packs together two statements at the same level
as the "if". The warning is misleading but is very noisy so it makes
sense to fix it.

bpo-38530: Refactor and improve AttributeError suggestions (GH-25776) 
- Make case-swaps half the cost of any other edit
- Refactor Levenshtein code to not use memory allocator, and to bail early on no match.
- Add comments to Levenshtein distance code
- Add test cases for Levenshtein distance behind a debug macro
- Set threshold to `(name_size + item_size + 3) * MOVE_COST / 6`.
  - Reasoning: similar to `difflib.SequenceMatcher.ratio()` >= 2/3:
```
"Multiset Jaccard similarity" >= 2/3
matching letters / total letters >= 2/3
(name_size - distance + item_size - distance) / (name_size + item_size) >= 2/3
1 - (2*distance) / (name_size + item_size) >= 2/3
1/3 >= (2*distance) / (name_size + item_size)
(name_size + item_size) / 6 >= distance
With rounding:
(name_size + item_size + 3) // 6 >= distance
```

bpo-43998: Default to TLS 1.2 and increase cipher suite security (GH-25778) 
The ssl module now has more secure default settings. Ciphers without forward
secrecy or SHA-1 MAC are disabled by default. Security level 2 prohibits
weak RSA, DH, and ECC keys with less than 112 bits of security.
:class:`~ssl.SSLContext` defaults to minimum protocol version TLS 1.2.
Settings are based on Hynek Schlawack's research.

bpo-41486: Fix initial buffer size can't > UINT32_MAX in zlib module (GH-25738) 
* Fix initial buffer size can't > UINT32_MAX in zlib module

After commit f9bedb630e, in 64-bit build,
if the initial buffer size > UINT32_MAX, ValueError will be raised.

These two functions are affected:
1. zlib.decompress(data, /, wbits=MAX_WBITS, bufsize=DEF_BUF_SIZE)
2. zlib.Decompress.flush([length])

This commit re-allows the size > UINT32_MAX.

* adds curly braces per PEP 7.

* Renames `Buffer_*` to `OutputBuffer_*` for clarity
