BufferedReader.read1() could leave the buffered object in a
reentrant (locked) state when an exception was raised while
allocating the output buffer.
This change ensures the internal buffered lock is always released
on error, keeping the object in a consistent state after failures.

The last remaining set of tests to split out that are focused on one
specific implementation portion (`bufferedio.c`).
test_io.test_general is now largely tests around `io.open` and module
properties (ex. pickling, class hierarchy, module members, etc).
This closes#138013.
Centralize `io` tests into the `test_io` module so they are easier to
find and work on. This will make it easier to split `test_general` which
takes 30+ seconds in a debug build on my machine.
This renames `test_bufio` to be `test_bufferedio` so that it matches
the implementation file name (`bufferedio.c`).
Validation performed:
Tests are run in parallel after change:
```bash
./python.exe -m test test_io -uall,largefile,extralargefile -M12G -j8
```
Docstring reformat in `test_io/__init__.py` looks reasonable:
```python
>>> import test.test_io
>>> help(test.test_io)
```
