Weak refs to Recording methods. Made the mutexes more simple for stream manager. Added extra guards and statements here and there. Code passes a sever stress test.

// #define DEBUGTRACE_ENABLED
Moved IndataHandler to its own implementation file. Refactored some code. Fixed race conditions when starting and stopping indatahandlers. It appears that this does not solve the segfault, but is at least mitigates some race conditions when constructors are not ready on an object, and avoiding the call of virtual functions of an object which destructor has already been called. Added some extra assert check that a function is called from the right thread. Put explicit start and stop methods in constructor / destructor of PyInDataHandler. WARNING: this means all .start() and .stop() methods should be removed. THIS IS AN API break!

#include "lasp_indatahandler.h"
StreamMgr handle now via shared pointers. InDataHandler stores weak pointers. Reset callback in PyInDataHandler could be problematic. Refactored the UlDaq code and moved to a subfolder.

Incallbacks should not return anything anymore. From inheritance to composition for InDataHandler code. StreamMgr singleton only weak ptr stored, this makes sure destruction from Python is more often done. UlDAQ code back to working.
