Added a few classes to the debug kit:

* BDebugMessageHandler: Interface with hooks for handling of debug messages. * BDebugContext: Essentially a C++ wrapper for struct debug_context, with handy methods for controlling a debugged team. * BTeamDebugger: Proxy for a debugged team. Derived from BDebugContext. * BDebugLooper: Wraps a main debug message loop. Any number of BTeamDebuggers can be added and associated with BDebugMessageHandlers. git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@35953 a95241bf-73f2-0310-859d-f6bbb57e9c96
