Improve library split parts

In prevision of further developments (like plugins)
the server is splitted in two parts: the server program
itself and the core library.

The client library is also splitted in two parts:
the compatibility part and the real client part.

+# Cynara
+
+[Cynara][1] is fast, simple and safe permission database
+service.
+Functions of Cynara are:
+* checking access for certain permission
+* holding permission database
+* simple, single function API - for checking permissions
+* thin client library - to make access control even more simple
+* ability to use external agent
+(in case of policies that can't be full processed in cynara and plugins)
+
+## API Overview
+
+Please refer to a wiki page on [Cynara's API][2].
+
+## Documentation
+
+Documentation is kept on [wiki][1].
+
+## Repositories
+
+Cynara repositories are available on:
+* GitHub - [samsung/Cynara][3] repository
+* tizen.org - [platform/core/security/cynara][4] repository - requires account on tizen.org
