dev-libs/open62541: Open source C implementation of OPC UA (new package)

open62541 (http://open62541.org) is an open source and free implementation of
OPC UA (OPC Unified Architecture) written in the common subset of the C99 and
C++98 languages. The library is usable with all major compilers and provides the
necessary tools to implement dedicated OPC UA clients and servers, or to
integrate OPC UA-based communication into existing applications. open62541
library is platform independent. All platform-specific functionality is
implemented via exchangeable plugins. Plugin implementations are provided for
the major operating systems.
