- FailGem5Device is gone.
- There are now changes directly made to the gem5 source.
- Gem5Connector is a helper class that is compiled inside the gem5 context to workaround problems with gem5 header in fail.
Things that are working:
- BPSingleListener
- MemAccessListener
- Save and restore simulator state

This commit *introduced* a segfault to the nanojpeg experiment. Indeed there is
no point in clearing m_FireList here:
1. Multiple active listeners match an event coming from the simulator. These
listeners are moved from their queue to m_FireList.
2. In a loop iterating over m_FireList, one of the listeners is triggered
(ListenerManager::triggerActiveListeners()). Context switches to an
experiment. The experiment explicitly (or implicitly, e.g., by terminating)
calls simulator.clearListeners().
3. ListenerManager::remove() clears all active (but not currently fired, or
about to be fired) listeners from the main listener queue (and additionally
all type-specific special containers). To prevent the "about to be fired"
listeners to fire, they are copied to m_DeleteList.
4. The loop mentioned in 2. does not trigger any listener mentioned in
m_DeleteList. Afterwards, m_FireList (and m_DeleteList) is cleared.
Clearing m_FireList in step 3 invalidates the iterator used in the loop from
steps 2 and 4. In fact, this problem was the reason we introduced the
m_DeleteList workaround in the first place.
This reverts commit r1817.

This is necessary as a temporary fix: Currently, campaign code cannot use
Fail*'s architecture abstractions at all (e.g., we cannot iterate over all
existing GP registers). Until this is corrected by separating a concrete
backend and architecture information (the latter being usable by a
campaign), we now at least can use register IDs.

Unfortunately, this does not (yet) work as advertised. I need to fight another
round of CMake battles before retrying. Reverting to previous state for now.
This reverts r1753.

ag++ is now called with a list of currently active aspect headers
(ag++ -a aspect1.ah -a aspect2.ah ...). This resolves several problems at
once:
- Build directories may be positioned arbitrarily now, they need not be
a subdirectory of the project anymore.
- Multiple build directories can coexist within the project tree. Before
this commit, the generated instantiate-*.ah aspect headers disturbed
neighboring build trees.
- Due to this, the regression test should be runnable much more easily
now.
- The build time was reduced by an average of about 10%.

We need to be able to grep for our manual changes. It doesn't help to
have variations with "TUDOS" or "BOCHS-MODIFIED" around. Please
understand "// DanceOS" comments as an abbreviation for "this code was
manually modified and needs to be manually ported once we switch to a
newer version of Bochs."
