This PR removes calls to and mentions of the `SecurityManager` and the
`doPrivileged` from the `java.net.InetAddress` and `sun.net.util.IPAddressUtil`
and related classes.
Noteworthy changes:
- the default value (`30s`) of the `networkaddress.cache.ttl` security property
responsible for successfull address lookups kept unchanged, the mention of SM
removed from the property description in the `net-properties.html` file.
- connect permission checks are removed from the `InetAddress`, and relevant
classes, like `SocketPermission`. `SocketPermission.initEphemeralPorts` was
also modified to remove `doPrivileged`.
- `RuntimePermission("inetAddressResolverProvider")` permission has been
removed from the system-wide `InetAddressResolver` initialization code.
`tier1` to `tier3` tests show no relevant failures.
