changes in WLAN module and hostname

[dusan-zervan]

I have found differences between 1.19.1 and latest nightly builds in WLAN module: documentation

It ruins my old programs, but I can adapt. However, why the new function network.hostname() is not accepting hostname longer than 15 characters? Is it a mistake or intended? I usually use longer hostnames.

15 characters is the old NetBIOS limit, but that might be coincidental.

It seems deliberate, from the recent changes to extmod/modnetwork.h
