Optimize `LOAD_FAST` opcodes into faster versions that load borrowed references onto the operand stack when we can prove that the lifetime of the local outlives the lifetime of the temporary that is loaded onto the stack.
Don't pass direct references to sockaddr members since their type may
not match PyArg_ParseTuple() types. Instead, use temporary 'int' and
'unsigned char' variables, and update sockaddr members afterwards.
On FreeBSD, treat BTPROTO_HCI node name as a bytes string,
not as an integer.
Use the standard `__ARM_ARCH` macro, which is supported by GCC and Clang.
The branching logic for of `__ARMEL__` has been removed so if the target
architecture supports v7+ instructions, a yield is emitted, otherwise a nop
is emitted. This covers both big and little endian scenarios.

When using --with-dtrace the resulting object file could be missing
specific CFLAGS exported by the build system due to the systemtap
script using specific defaults.
Exporting the CC and CFLAGS variables before the dtrace invocation
allows us to properly apply CFLAGS exported by the build system
even when cross-compiling.
The fix does not affect the dtrace invocation on Solaris/macOS.
* Rename 'defined' attribute to 'in_local' to more accurately reflect how it is used
* Make death of variables explicit even for array variables.
* Convert in_memory from boolean to stack offset
* Don't apply liveness analyis to optimizer generated code
* Add 'out' parameter to stack.pop
We fix a use-after-free in the `find`, `findtext` and `findall` methods of `xml.etree.ElementTree.Element`
objects that can be triggered when the tag to find implements an `__eq__` method that mutates the
element being queried.
`email.message.Message` objects now validate header names specified via `__setitem__`
or `add_header` according to RFC 5322, §2.2 [1].
In particular, callers should expect a ValueError to be raised for invalid header names.

Update os.walk example to be more modern, skip `__pycache__` dirs rather than `CVS` dirs.

Minor readability fix in PyUnstable_GC_VisitObjects
Replaces `if (visit_generation())` with `if (visit_generation() < 0)`,
since we are checking for the failure case, and it's confusing to have
that be implicitly `true`.
Also fixes a misspelt variable name.
