bochs bugfix: store the timer ID for correct deregistration
...
Over a few indirections, this broke Bochs' 16550 UART simulation after
transferring a few hundreds of bytes. The UART uses internal timers to
simulate the configured baud rate; these timers cease to work after
repeated misuse from the Fail/Bochs bridge.

bochs: trace REP/REPZ/REPNZ iterations
...
This allows single-stepping through REP/REPZ/REPNZ iterations. We mainly
need this for a little more realistic timing model when, e.g., copying
large memory areas with REP MOVSB.
Be aware that memory-access tracing only works reliably for REPxx-prefixed
instructions if Bochs was configured with --disable-repeat-speedups, as
this Bochs optimization completely circumvents the usual memory access
paths.

Revert "ListenerManager bugfix (segfault): [...]"
...
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.
