gh-101678: Merge math_1_to_whatever() and math_1() (#101730)
`math_1_to_whatever()` is no longer useful, since all existing uses of it convert to `float`.
Earlier versions of Python used `math_1_to_whatever` with an integer target; see
gh-16991 for the PR where that use was removed.

gh-99108: Replace SHA2-224 & 256 with verified code from HACL* (#99109)
replacing hashlib primitives (for the non-OpenSSL case) with verified implementations from HACL*. This is the first PR in the series, and focuses specifically on SHA2-256 and SHA2-224.

This PR imports Hacl_Streaming_SHA2 into the Python tree. This is the HACL* implementation of SHA2, which combines a core implementation of SHA2 along with a layer of buffer management that allows updating the digest with any number of bytes. This supersedes the previous implementation in the tree.

@franziskuskiefer was kind enough to benchmark the changes: in addition to being verified (thus providing significant safety and security improvements), this implementation also provides a sizeable performance boost!

```
---------------------------------------------------------------
Benchmark                     Time             CPU   Iterations
---------------------------------------------------------------
Sha2_256_Streaming            3163 ns      3160 ns       219353     // this PR
LibTomCrypt_Sha2_256          5057 ns      5056 ns       136234     // library used by Python currently
``` 

The changes in this PR are as follows:
- import the subset of HACL* that covers SHA2-256/224 into `Modules/_hacl`
- rewire sha256module.c to use the HACL* implementation

gh-76961: Fix buildbot failures in test_pep3118 (#101587)
This PR fixes the buildbot failures introduced by the merge of #5561, by restricting the relevant tests to something that should work on both 32-bit and 64-bit platforms. It also silences some compiler warnings introduced in that PR.

gh-76961: Fix the PEP3118 format string for ctypes.Structure (#5561)
The summary of this diff is that it:

* adds a `_ctypes_alloc_format_padding` function to append strings like `37x` to a format string to indicate 37 padding bytes
* removes the branches that amount to "give up on producing a valid format string if the struct is packed"
* combines the resulting adjacent `if (isStruct) {`s now that neither is `if (isStruct && !isPacked) {`
* invokes `_ctypes_alloc_format_padding` to add padding between structure fields, and after the last structure field. The computation used for the total size is unchanged from ctypes already used.

This patch does not affect any existing aligment computation; all it does is use subtraction to deduce the amount of paddnig introduced by the existing code.

---

Without this fix, it would never include padding bytes - an assumption that was only
valid in the case when `_pack_` was set - and this case was explicitly not implemented.

This should allow conversion from ctypes structs to numpy structs

gh-59956: Clarify Runtime State Status Expectations (gh-101308)
A PyThreadState can be in one of many states in its lifecycle, represented by some status value.  Those statuses haven't been particularly clear, so we're addressing that here.  Specifically:

* made the distinct lifecycle statuses clear on PyThreadState
* identified expectations of how various lifecycle-related functions relate to status
* noted the various places where those expectations don't match the actual behavior

At some point we'll need to address the mismatches.

(This change also includes some cleanup.)

It remains unsupported, but at least is possible now for experimentation.

gh-99952: [ctypes] fix refcount issues in from_param() result. (#100169)
Fixes a reference counting issue with `ctypes.Structure` when a `from_param()` method call is used and the structure size is larger than a C pointer `sizeof(void*)`.

This problem existed for a very long time, but became more apparent in 3.8+ by change likely due to garbage collection cleanup timing changes.

When getaddrinfo returns an error, the output pointer is in an unknown state
Don't call freeaddrinfo on it.  See the issue for discussion and details with
links to reasoning.  _Most_ libc getaddrinfo implementations never modify the
output pointer unless they are returning success.

gh-83122: Deprecate testing element truth values in `ElementTree` (#31149)
When testing element truth values, emit a DeprecationWarning in all implementations.

This had emitted a FutureWarning in the rarely used python-only implementation since ~2.7 and has always been documented as a behavior not to rely on.

Matching an element in a tree search but having it test False can be unexpected. Raising the warning enables making the choice to finally raise an exception for this ambiguous behavior in the future.

gh-59956: Clarify GILState-related Code (gh-101161)
The objective of this change is to help make the GILState-related code easier to understand.  This mostly involves moving code around and some semantically equivalent refactors.  However, there are a also a small number of slight changes in structure and behavior:

* tstate_current is moved out of _PyRuntimeState.gilstate
* autoTSSkey is moved out of _PyRuntimeState.gilstate
* autoTSSkey is initialized earlier
* autoTSSkey is re-initialized (after fork) earlier
