Implements #33260.

Still part of #34218.

Latest TGenTools contain a fix for correctly computing the start time
of failed streams. We have to update our unit tests.

Related to #30362.

Fixes #40006.

With this change we include more detailed error codes in visualization
output. In order to do so we map TGen transfers/streams to TorCtl
STREAM event details based on source ports and unix_ts_end timestamps.
This code reuses some concepts used in metrics-lib.

Implements #34218.

Implements #40005.

The bug was that we were using the wrong Analysis class in measure
mode:

AttributeError: 'Analysis' object has no attribute 'add_torctl_file'

Turns out that stream_info/recvsize contains a string, not an int.

This schema can be used to validate an analysis file using version 3.0
by using the following commands:

```
pip3 install jsonschema
unxz final_onionperf.analysis.json.xz
jsonschema -i final_onionperf.analysis.json onionperf-3.0.json
```

Implements #40003.
