[LibAfgs]: Support function to build and maintain Af-Arch servers.

This layer allows to write Af-Arch servers, making things easy to invoke SQL statements, exchange message to answer client requests, drop log on some interesting event or get access to settings stored on the Af-Arch server config file.

Although, af-gen tool actually generates mostly completed servers, code generated is written on top of this library.

You'll have to use this library to develop server side components.

It is posible to build up an Af-Arch server using this library directly. But, if you are planning to develop a server component in a more productive way, it is recomended to start using af-gen tool.
