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.

Tests for the tokenize module.

The tests can be really simple. Given a small fragment of source
|

code, print out a table with tokens. The ENDMARKER is omitted for

brevity.

There are some standard formatting practices that are easy to get right.

|
|
|
|
Some people use different formatting conventions, which makes
|
|
untokenize a little trickier. Note that this test involves trailing
|
|
whitespace after the colon. Note that we use hex escapes to make the
|
|
two trailing blanks apparent in the expected output.
|
|
