Support for BDM B+ debug module (52223/52235)

2nd June 2008 Support has been added for the Coldfire Debug B+ module including the extra hardware breakpoints this version of the debug module provides. Testing on 52223 and 52235 processors has been completed. The gdbserver application has had a number of important bugs fixed and a new option to forced all breakpoints to use hardware breakpoints.
