When trying to reproduce a reported issue with telnetd,
it took me a bit to find out a working config with telnetd.
I don't want to repeat the process again in future.
OTOH, I don't feel it's worth to have a separate config for this.
Enable a few things convenient for testing network stuff
- telnetd
- iperf
- NET_STATISTICS
- Bump NET_NACTIVESOCKETS
Stack related
- Enable interrupt stack
- Tweak stack sizes
- STACK_COLORATION
- SYSTEM_STACKMONITOR
Debug stuff
- Enable assertions
- Enable some WARN/ERROR logs
Misc
- Disable C++ as it does nothing for the rest of the config and
it's expensive (involving a download of the library)
