Feature #2451

Updated by Alex Afanasyev about 9 years ago

Refactoring code from the SecPubInfo interface, and more precisely the sec-pub-info-sqlite3 concrete implementation into a series of abstractions. 

 The general design is as follows: 

   - 
      SecIdentityManager - a mechanism class that is used to interact with the TPM, Pib, and Identities 
   - 
      SecIdentityInfo      - a value-semantic class used to manage information relating to a particular identity,  
                           including accessing any keys associated with the Identity 
   - 
      SecKeyInfo              - a value-semantic type used to manage information relating to a particular key including 
                           the type of key and associated certificates 
   - 
      DbUtil               - a utility class to encapsulate common functionality used to access sqlite database 

 More complete public interfaces are included below. 

 A current topic relevant to the design that needs to be settled are the circumstances in which we should throw an exception.
