Logging macros are not namespaced

Line 29 in bd13aee

#define LOG_TRACE(__logger__, ...) { if (__logger__ && __logger__->should_log(spdlog::level::trace)) { __logger__->trace(__VA_ARGS__); }}

As this is a library, it would be appropriate to namespace these global macros, e.g. LOG_INFO -> FREEOPCUA_LOG_INFO to avoid conflicting with client code. We have a codebase that does internal logging and now needs to hack around this. Probably we should rename also, but for a library even more important.

Is this library maintained actually? It kinda seems dead.
