The base domain is composed by the top level domain (such as .org, .com,
.co.uk, etc) plus the second level domain, for example for
myhost.mydomain.com it will return mydomain.com.
Note that null will be returned for private URLs (those not ending
with any well known TLD) because choosing a base domain for them
would be totally arbitrary.
Prior to libsoup 2.46, this function required that hostname be in
UTF-8 if it was an IDN. From 2.46 on, the name can be in either
UTF-8 or ASCII format (and the return value will be in the same
format).
