- 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%.

does not account for arrays of instructions provided
by one virtual instruction trace cache entry ->
passing the current instruction directly.
ALUInstr not yet completely tested.

Fix 1: A result message with a nonexistent or invalid run ID must be
ignored in any case. 0 is only OK for NEED_WORK messages, clients
communicating a result must know the ID.
Fix 2: Tell the client the run ID in the first place ...

A campaign server now tells all clients a unique run ID (the UNIX timestamp
when it was started). This allows us to ignore results from "old" clients
that talked to another server before, and to tell them to die.
