* Renamed _BDeviceAddOn_ to DeviceAddOn, and put it into the BPrivate namespace.
* Moved the DeviceManager functionality into the AddOnManager - this also
solves a locking issue, as BInputServerDevice::Control() was called in the
context of the DeviceManager before.
* The AddOnManager now uses the BPathMonitor to monitor the devices that
BInputServerDevices ask for - this greatly simplifies the code.
* Got rid of TList.h, and use ObjectList.h instead.
* Added PathList class that has a list of paths with reference count, used by
DeviceAddOn and the AddOnManager.
* DeviceAddOn got an actual implementation that lives in InputServerDevice.cpp.
* Added an experimental BInputServerDevice::AddDevices() that could be used
instead of recursing over devices manually. It replaces the functionality
that was found in the DeviceManager before (this was done implicitely for
all monitored devices).
* Greatly cleaned up and simplified the AddOnManager.
* Also fixed lots of potential errors/leaks when things go wrong.
* Removed the extra locker in AddOnManager - its BLooper lock is now used
instead.
* Replaced PRINT()/PRINTERR() macros in the AddOnManager with TRACE(), and
ERROR(), both now use debug_printf().
* Hopefully this fixes the problem that I don't have keyboard under VirtualBox
from time to time.
