Make more robust with respect on invalid input data

* When encountering scheduling data referring to an unknown thread, add
a dummy thread for it. This prevents a crash when processing the
per-thread events later.
* Make warning output more uniform.

* Model: Added class IOScheduler, a list of IOSchedulers, and a methods to
access it.
* ModelLoader:
- Also add IOSchedulers to the model.
- Sort the per thread list of IORequests by start time.
- Added a bit of output in the _HandleIO*() methods when we don't know a
request or operation.

* Model: Added classes IOOperation and IORequest, and extended Thread to own a
list of IORequests.
* ModelLoader: Process the I/O request and operation related events and create
the per-thread list of requests.

ModelLoader does now also create an event array per thread with all the events
for that thread.

* Although it takes a bit of memory, the Model also stores an array with
pointers to all events now. This allows for backward iteration.
* Model::ThreadWaitObjectGroup: Added a few convenience getters.
* Added functions thread_state_name() and wait_object_type_name() to translate
a ThreadState respectively a wait object type into a readable string.

* Also compute the number of CPUs and the idle time of each CPU.
* Show the CPU count and the total idle time in the "General" page.

* The system profiler scheduling event structures sport nanotime_ts now.
* Adjusted the DebugAnalyzer to handle nanosecond times.

* Moved ThreadInfo from ModelLoader to Model. And renamed it to
ThreadSchedulingState. Also moved the management of the thread scheduling
states into a new model class SchedulingState, which is now used by
ModelLoader.
* Added scheduling state snapshots to Model. The ModelLoader adds a complete
snapshot every 1024 events, so that seeking to scheduling state at a time
can be done quickly.
* [Featuring stippi] Added actual functionality to the scheduling page. It
shows the scheduling activity of all threads and one can zoom in and out.
Looks somewhat ugly and is work in progress.

headers/private/kernel/util/OpenHashTable.h, Hugo's version, is a bit nicer than
Tracker's OpenHashTable.h which it should eventually replace. We've renamed the
class to BOpenHashTable and changed the interface slightly so that HashTableLink
became superfluous.
Adapted all the code that used it. Since the OpenHashTables no longer clash,
this should fix the GCC4 build.

wait for the loader thread.
* MainWindow::Quit() aborts the loader now.
