Added support for exception chains in EBaseException.

The EBaseException has been modified to provide constructors that
can be used to chain the cause of the exception. This way the root
cause of the exception can be traced back to help troubleshooting.

Some codes have been modified to utilize the proper exception
chaining as examples.
