Move compatibility helpers for the different Python versions to a new
asyncio.compat module.

If exc_traceback is None we shouldn't print a traceback header
like described in the documentation.

The fix for Issue #21217 introduced a regression that caused
`inspect.getsource` to return incorrect results on nested
functions.  The root cause of the regression was due to
switching the implementation to analyze the underlying
bytecode instead of the source code.

This commit switches things back to analyzing the source code
in a more complete way.  The original bug and the regression
are both fixed by the new source code analysis.

This commit simplifies async/await tokenization in tokenizer.c,
tokenize.py & lib2to3/tokenize.py.  Previous solution was to keep
a stack of async-def & def blocks, whereas the new approach is just
to remember position of the outermost async-def block.

This change won't bring any parsing performance improvements, but
it makes the code much easier to read and validate.
