AddLink() fails when memory allocation fails or no free port is available; both are error conditions. However, functions such as FindUdpTcpIn() were converting such failures to PKT_ALIAS_IGNORED, which effectively means, "pass the packet without translation," which isn't what we want. Fix the problem by making sure that AddLink() errors are converted to PKT_ALIAS_ERROR where appropriate. The diff is a bit large but is mostly mechanical: functions like TcpAliasOut() are converted to return a result code, and an additional out-parameter is added to return the alias_link pointer.
