Successful exploitation could lead to arbitrary code execution.
The bug can be reproduced by running the following in a browser:
```
const formData = new FormData();
for (let i = 0;i < 33;++i) { formData.append("foo", i.toString()); }
await fetch("http://esp.local", { method: 'POST', body: formData });
```
* add opportunity for more than one retry to _uploadReadByte
* an alternative timeout-based method to making _uploadReadByte more resilient
* move timing variables in the correct scope
* implement and use client.getTimeout instead of hard-coded timeout in _uploadReadByte
* add missing return
* some refactoring to address respecting the timeout in a potentially deadlocked connection
* fix spelling in comment
* address review comments; move impl to cpp file for getTimeout, and remove local variable for currentMillis
* remove redundant cast
* need to check for timeout outside the inner while as well
* update WebUpdate example to print something in unexpected callback condition
* update log_e messages per review comments
* Webserver fix logging (#1)
* Change logging to use esp32-hal-log.h
fixes#2355
* adjust log parameter output positions, reduce lines
The DEBUG_ESP method used less lines than I originally set `log_v` to use when displaying the details of the received params ("@" and "=" indexes, and File info on a single line)
