noproxy: also match with adjacent comma
If the host name is an IP address and the noproxy string contained that
IP address with a following comma, it would erroneously not match.
Extended test 1614 to verify this combo as well.

noproxy: fix tail-matching
Also ignore trailing dots in both host name and comparison pattern.
Regression in 7.86.0 (from 1e9a538e05c0)

noproxy: tailmatch like in 7.85.0 and earlier
A regfression in 7.86.0 (via 1e9a538e05c010) made the tailmatch work
differently than before. This restores the logic to how it used to work:
All names listed in NO_PROXY are tailmatched against the used domain
name, if the lengths are identical it needs a full match.
Update the docs, update test 1614.
