[jdk11u-dev] RFR: 8263364: sun/net/www/http/KeepAliveStream/KeepAliveStreamCloseWithWrongContentLength.java wedged in getInputStream

[Goetz Lindenmaier]

I backport this for parity with 11.0.15-oracle.

I did the following changes to the patch:
 * I also include the changes from "8222938 Replace wildcard address with loopback or local host in tests - part 21".
    As this is a cleanup it is pointless to undo all the changes in the patch.
 * I removed "...".formatted() calls.  That is not supported in 11.
