BUG/MINOR: http_fetch: make hdr_ip() resistant to empty fields
The fix in commit 7b0e00d94 ("BUG/MINOR: http_fetch: make hdr_ip() reject
trailing characters") made hdr_ip() more sensitive to empty fields, for
example if a trusted proxy incorrectly sends the header with an empty
value, we could return 0.0.0.0 which is not correct. Let's make sure we
only assign an IPv4 type here when a non-empty address was found.
This should be backported to all branches where the fix above was
backported.
