Joel Cunningham 920ee2d07e sntp: use const for servername
This adds const to the sntp servername get/set API and internal storage

SNTP's usage of this name is read only and SNTP only passes it to dns_gethostbyname()

This was found by compiling with GCC -Wwrite-strings which makes the literal
SNTP_SERVER_ADDRESS a const string. This then produced warnings with sntp_init()'s
call to sntp_setservername()
