[3.12] gh-62260: Fix ctypes.Structure subclassing with multiple layers (GH-13374) (GH-113623)
The length field of StgDictObject for Structure class contains now
the total number of items in ffi_type_pointer.elements (excluding
the trailing null).
The old behavior of using the number of elements in the parent class can
cause the array to be truncated when it is copied, especially when there
are multiple layers of subclassing.

[3.12] gh-113320: Reduce the number of dangerous `getattr()` calls when constructing protocol classes (#113401) (#113722)
- Only attempt to figure out whether protocol members are "method members" or not if the class is marked as a runtime protocol. This information is irrelevant for non-runtime protocols; we can safely skip the risky introspection for them.
- Only do the risky getattr() calls in one place (the runtime_checkable class decorator), rather than in three places (_ProtocolMeta.__init__, _ProtocolMeta.__instancecheck__ and _ProtocolMeta.__subclasscheck__). This reduces the number of locations in typing.py where the risky introspection could go wrong.
- For runtime protocols, if determining whether a protocol member is callable or not fails, give a better error message. I think it's reasonable for us to reject runtime protocols that have members which raise strange exceptions when you try to access them. PEP-544 clearly states that all protocol member must be callable for issubclass() calls against the protocol to be valid -- and if a member raises when we try to access it, there's no way for us to figure out whether it's a callable member or not!

An active loop is only used when the `timeout` parameter is used on
POSIX.
When no timeout is used, the code calls `os.waitpid` internally (which puts
the process on a sleep status). On Windows, the internal Windows API
call accepts a timeout parameter, so that is delegated to the OS.

Fix error check on mmap(2)
It should check MAP_FAILED instead of NULL for error.

On success, mmap() returns a pointer to the mapped area.
On error, the value MAP_FAILED (that is, (void *) -1) is
returned, and errno is set to indicate the error.

A typo left this check broken so many of us who do out-of-tree builds
were seeing strange failures due to bad `Python/frozen_modules/*.h`
files being picked up from the source tree and used at build time from
different Python versions leading to errors like:
`Fatal Python error: _PyImport_InitCore: failed to initialize importlib`
Or similar once our build got to an "invoke the interpreter"
bootstrapping step due to incorrect bytecode being embedded.

When wrapped, `_SSLProtocolTransport._force_close(exc)` is called just like in the unwrapped scenario `_SelectorTransport._force_close(exc)` or `_ProactorBasePipeTransport._force_close(exc)` would be called, except here the exception needs to be passed through the `SSLProtocol._abort()` method, which didn't accept an exception object.
This commit ensures that this path works, in the same way that the uvloop implementation of SSLProto passes on the exception (on which the current implementation of SSLProto is based).
