There is no reason for this watcher to be attached to any particular loop.
This should make it safe to use regardless of the lifetime of the event loop running in the main thread
(relative to other loops).

The test failed on a buildbot because the pointer was only 7 hex characters. To be safe,
I bumped it down to 3: 4 in case we have 32-bit platforms, and 3 in case the pointer is very small.

_Py_block_ty defines four types of block, FunctionBlock, ClassBlock, ModuleBlock and AnnotationBlock.
But _symtable_entry.ste_type only comments three of them, I think it's better both sides are consistent.
This PR reverts gh-93369 and gh-97896 because they've made asyncio tests unstable. After these PRs were merged, random GitHub action jobs of random commits started to fail unrelated tests and test framework methods.
The reverting is necessary because such shrapnel failures are a symptom of some underlying bug that must be found and fixed first.
I had a hope that it's a server overload because we already have extremely rare disc access errors. However, one and a half day passed, and the failures continue to emerge both in PRs and commits.
Affected issue: gh-93357.
First reported in https://github.com/python/cpython/pull/97940#issuecomment-1270004134.
* Revert "gh-93357: Port test cases to IsolatedAsyncioTestCase, part 2 (#97896)"
This reverts commit 09aea94d29.
* Revert "gh-93357: Start porting asyncio server test cases to IsolatedAsyncioTestCase (#93369)"
This reverts commit ce8fc186ac.
In `_warnings.c`, in the C equivalent of `warnings.warn_explicit()`, if the module globals are given (and not None), the warning will attempt to get the source line for the issued warning. To do this, it needs the module's loader.
Previously, it would only look up `__loader__` in the module globals. In https://github.com/python/cpython/issues/86298 we want to defer to the `__spec__.loader` if available.
The first step on this journey is to check that `loader == __spec__.loader` and issue another warning if it is not. This commit does that.
Since this is a PoC, only manual testing for now.
```python
# /tmp/foo.py
import warnings
import bar
warnings.warn_explicit(
'warning!',
RuntimeWarning,
'bar.py', 2,
module='bar knee',
module_globals=bar.__dict__,
)
```
```python
# /tmp/bar.py
import sys
import os
import pathlib
# __loader__ = pathlib.Path()
```
Then running this: `./python.exe -Wdefault /tmp/foo.py`
Produces:
```
bar.py:2: RuntimeWarning: warning!
import os
```
Uncomment the `__loader__ = ` line in `bar.py` and try it again:
```
sys:1: ImportWarning: Module bar; __loader__ != __spec__.loader (<_frozen_importlib_external.SourceFileLoader object at 0x109f7dfa0> != PosixPath('.'))
bar.py:2: RuntimeWarning: warning!
import os
```

This is a small performance improvement, especially for one or two hot
places such as _handle_fromlist() that are called a lot and the
.format() method was being used just to join two strings with a dot.
Otherwise it is merely a readability improvement.
We keep `_ERR_MSG` and `_ERR_MSG_PREFIX` as those may be used elsewhere for canonical looking error messages.
Right now, the tokenizer only returns type and two pointers to the start and end of the token.
This PR modifies the tokenizer to return the type and set all of the necessary information,
so that the parser does not have to this.
