[avahi] Hostname case-sensitivity

[John McCabe]

Hi Esko,

Thank you for your reply and the reference to rfc6762. Interestingly, a 
short while after sending my message, pings to lower-case versions 
worked; I'm not sure why, although I did do avahi-browse -a in between.

It's intriguing; I'm going to experiment with this embedded build to see 
if I can work out more about what's happening.

Best Regards

John
