Most importantly, this resolves the issues with functions and types defined in __main__.
It also expands the number of supported objects and simplifies the implementation.

The assertion reflected a misunderstanding of situations where "hidden" variables might exist,

gh-135335: flush stdout/stderr in forkserver after preloading modules (GH-135338)
If a preloaded module writes to stdout or stderr, and the stream is buffered,
child processes will inherit the buffered data after forking. Attempt to
prevent this by flushing the streams after preload.

gh-119180: Only fetch globals and locals if necessary in `annotationlib.get_annotations()` (GH-135644)
(cherry picked from commit 504ae606e1)
Co-authored-by: Victorien <65306057+Viicos@users.noreply.github.com>
The Emscripten path resolver uses the same mechanism for resolving `..`
at a file system root as for resolving symlinks. This is because
roots don't store their mountpoints. If the parent of a node is itself,
it is a root but it might be a mountpoint in some other file system.
If a path has enough `..`'s at the root, it will return ELOOP.
Enough turns out to be 49.

As noted in the new tests, there are a few situations we must carefully accommodate
for functions that get pickled during interp.call(). We do so by running the script
from the main interpreter's __main__ module in a hidden module in the other
interpreter. That hidden module is used as the function __globals__.

Co-authored-by: Hugo van Kemenade <1324225+hugovk@users.noreply.github.com>
For several builtin functions, we now fall back to __main__.__dict__ for the globals
when there is no current frame and _PyInterpreterState_IsRunningMain() returns
true. This allows those functions to be run with Interpreter.call().
The affected builtins:
* exec()
* eval()
* globals()
* locals()
* vars()
* dir()
We take a similar approach with "stateless" functions, which don't use any
global variables.

gh-67022: Document bytes/str inconsistency in email.header.decode_header() and suggest email.headerregistry.HeaderRegistry as a sane alternative (GH-92900)
* gh-67022: Document bytes/str inconsistency in email.header.decode_header()
This function's possible return types have been surprising and error-prone
for the entirety of its Python 3.x history. It can return either:
1. `typing.List[typing.Tuple[bytes, typing.Optional[str]]]` of length >1
2. or `typing.List[typing.Tuple[str, None]]`, of length exactly 1
This means that any user of this function must be prepared to accept either
`bytes` or `str` for the first member of the 2-tuples it returns, which is a
very surprising behavior in Python 3.x, particularly given that the second
member of the tuple is supposed to represent the charset/encoding of the
first member.
This patch documents the behavior of this function, and adds test cases
to demonstrate it.
As discussed in bpo-22833, this cannot be changed in a backwards-compatible
way, and some users of this function depend precisely on the existing
behavior.
Add warnings about obsolescence of 'email.header.decode_header' and 'email.header.make_header' functions.
Recommend use of `email.headerregistry.HeaderRegistry` instead, as suggested
in https://github.com/python/cpython/pull/92900#discussion_r1112472177
