Main/Event: eliminate unused parameter

Main/GuestCtrl: Don't keep ComObjPtr of parents in internal listeners.

Main/GuestCtrl: Reference counting bugfixes, handle more directoryCreate errors.

Main/GuestCtrl: Bugfixes: - Hold lock while registering wait event in GuestProcess::waitFor() - Fixes for GuestProcess::waitFlagsToResultEx() - Use public wait events for internal GuestFile methods - Remove wait event from all other event groups when signaled

GuestCtrl: Main/VBoxManage: More checks for object pointers, minor logging adjustments.

Guest Control: - Implemented IGuestSession::DirectoryRemove, IGuestSession::DirectoryRemoveRecursive, IGuestSession::DirectoryRename + IGuestSession::FileRename. - Added appropriate commands to VBoxManage (basic support for now). - Implemented support for proper guest session process termination via SCM. - Implemented support for internal anonymous wait events which are not relying on the public API's VBoxEventType_T. - Various bugfixes.

Main/GuestFileImpl.cpp: More locking.

Main/GuestCtrl: Fire IGuestFile events in every case; there might we waiters depending on it. seekAt() is now accepting relative offsets.

Main/GuestCtrl: Check for data to be written.

GuestCtrl/IGuestFile: Fixed initial offset reporting when using IGuestSession::openFileEx().

Warnings.

IGuestFile: Expose the file's ID. Nice to have for information purposes.

Main/GuestFileImpl.cpp: More guest error to string translations.

Main/IGuestFile: Changed disposition and openMode parameters being wstrings instead of ulongs (related to r88105), matching the IGuestSession::openFile / openFileEx calls.

GuestCtrl: Update for IGuestFile; some renaming.

Guest Control: Adjustments for supporting < 4.3 Guest Additions in conjunction with the new guest session, extended testcase (now passing using latest 4.2 Guest Additions with latest trunk).

Main: Removed IGuestErrorInfo, added new attribute resultDetail to IVirtualBoxErrorInfo for (optionally) providing more details on the error happened.

Main/GuestCtrl: Use active listeners instead of passive ones because of performance reasons (untested).

GuestCtrl: Added abstract IGuestProcessIOEvent event, removed duplicate code, making the testdriver execution tests pass.

GuestCtrl: More event handling code for IGuestFile and IGuestSession.

GuestCtrl: Added EventSource getters + OnGuestFileRegistered event.

Build fix.

GuestCtrl: Implemented using (public) VirtualBox events instead of own callback mechanisms. Bugfixes for testcases (still work in progress).

GuestCtrl: More stuff for IGuestFile and IGuestSession handling (work in progress).

GuestCtrl: Infrastructure changes for handling and executing dedicated guest sessions and protocol versioning (untested, work in progress).
