add LOCK() for proxy related data-structures - fix #1560 by properly locking proxy related data-structures - update GetProxy() and introduce GetNameProxy() to be able to use a thread-safe local copy from proxyInfo and nameproxyInfo - update usage of GetProxy() all over the source to match the new behaviour, as it now fills a full proxyType object - rename GetNameProxy() into HaveNameProxy() to be more clear
