minor changes, just for testing...
Add testboard to HAL, add HAL to API
Add explicit destructor to destroy the HAL object.
Documentation of the first HAL member functions
Add first HAL functions, mainly to connect to the board and a first idea how to
check RPC versions
Removed FindDTB function from CTestboard class. This should only provide the RPC
boilerplate but no actual code. Moved the functionality into the HAL class.
