ecos: fix golden-run runtime conversion
...
BochsController::getTimerTicksPerSecond() only works reliably when the
simulation is already running (e.g., after a restore()). This broke
timeout conditions for the very first experiment in a FailBochs instance.

ecos: record simulated runtime
...
As the eCos kernel tests do not sufficiently check for failures, a
(compared to the golden run) measurably *reduced* simulation time can be
used as an indication for SDC.

When eCos is built as a multiboot binary, some of its data structures
are still at very low (<<1M) addresses, but the rest moves to
addresses >1M. This change makes sure our invalid mem access
detection is not overly generous.

ElfReader: Support for Section and Symbol size.

- getSection/getSymbol now returns an ElfSymbol reference.
Searching by address now searches if address is within
symbol address and symbol address + size.
So we can test, if we are *within* a function, object or
section and not only at the start address.

ecos_kernel_test: updates due to architecture changes (ElfReader still NOT working properly)
...
At the moment, the experiment only works with a hard-coded address for the _stext symbol because the ElfReader cannot extract the symbol's address from the elf-binary. The experiment has been tested locally with PREREQUISITES = 1 and PREREQUISITES = 0. In the latter case, the test only considered the client/server communication, i.e., no FI has been performed at all (NOT tested yet).

BochsRegister.hpp and BochsRegisterIDs.hpp not needed anymore
...
The includes of these headers have already been removed from the experiments. In the current code, the content of the header BochsRegister.hpp is rather simply copied to x86/Architecture.hpp. It is therefore necessary to revisit the code soon (especially the FIXME related to register IDs).
Another problem is that there is no generalization of register IDs. Thus, all experiments are currently specific to a concrete architecture (which is not desired).

ecos: use multiple intermediate states to speed up experiments (disabled)
...
This modification creates and uses multiple intermediate snapshot states
(one every 1,000,000 instructions) to fast-forward to the FI site.
Unfortunately this doesn't work yet; the trace seems to change in many (not
all!) cases we do this. One possible cause could be an incorrect
(off-by-one or alike?) restoration of the serial device timers, and
therefore an earlier/later transition to "output buffer empty", resulting
in eCos' serial putc function needing a different amount of polling loop
iterations. Needs more investigation.
