CL: Core dump analysis improvements

All the platforms except esp32 (which uses heavily patched 9.0 from IDF) and esp8266 (doesn't use RTOS at all) are using the same version of FreeRTOS now.

Check response code, make sure it's 101.
Pass http_message to the client to keep it appraised.
This represents a slight change in the API -
in case of an error MG_EV_WEBSOCKET_HANDSHAKE_DONE will now be delivered where previosuly connection would just hang.
Clients that do not examine the argument may for a moment think handshake has succeeded but in fact connection will be closed immediately.

cs_log_set_filter() is removed in favor of cs_log_set_file_level() which
allows setting log verbosity of individual files and/or lines.

E.g.: `mg_=1,mjs=1,=4` - level for for everything except mjs and mongoose.

We use the fact that we are usually pretty careful with our file names and use prefixes consistently.

In mos, `debug.file_level` sets the option on boot and `Sys.SetDebug` is updated to parse `file_level` option to change it at runtime.

CL: Log file:line instead of function; add cs_log_set_file_level()

Replacement for fw_meta.py commands and also supports unbundling .hex files.

General syntax is:

```

Example of building a mos fw bundle for ESP8266:
```
 $ mos create-fw-bundle -o fw.zip --platform esp8266 --build-info=build_info.json \
    boot:addr=0x0,src=rboot.bin,update=false \
