Fix a crash that occurs when `parser.finish()` is called during `parser.execute()`. In this particular case, this happened because a 100 continue response is a place in which `.end()` can be called which can in turn lead to a write error, which is emitted synchronously, thus inside the outer `parser.execute()` call. Resolve that by delaying the `parser.finish()` call until after the `parser.execute()` call is done. This only affects v12.x, because on later versions, errors are not emitted synchronously. Fixes: nodejs#15102
Since the tests only crash on v12.x, this commit adds separate regression tests. Refs: nodejs#15102

@nodejs/http Can anybody review this? Only the first commit needs reviews, the remainder is just a backport of #34250 |

Can I ask what is left in the process to get this merged into 12.x, or if there is anything we can do to help? |

@lsr0 I don’t think there’s anything missing here, I’ll try to make sure it goes into the next release. |
