35026de2d8 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.

9decf95a09 ecos: specific traps are OK for two benchmarks 
The "except1" and "clockcnv" benchmarks explicitly cause a trap and handle
it in their own trap handler.  This, of course, isn't a bad experiment
outcome.

a0e6ddd519 ecos: fault-space cutoff specific for this campaign 
For the eCos kernel test campaign we define a relatively "special" metric
to compare FI results from different applications:  Instead of aligning
the fault-space dimensions (e.g., by artificially adding "don't care" space
to the right for shorter application variants), we only keep the data
address axis constant.  The rationale behind this is that -- despite the
benchmark applications' run-to-completion behavior -- an operating system's
scheduler usually runs ad infinitum, and that we therefore can extrapolate
from a short application run to any longer period.

In essence, this means we use a failure/experiment-length quotient (ignoring
the Y axis for simplicity, as it is constant in size) to compare
application variants, instead of an absolute failure count.  One important
side effect is that we do not punish any application slowdown with this
metric.  (And simply prolongating non-susceptible program sections with,
e.g., NOPs, seemingly "improves" fault tolerance.)

a29ad39f5e explicit aspect activation 
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%.

f9c96ddf2d prefix internal libraries to avoid naming conflicts with system libraries 
This is a precaution to avoid current and future naming conflicts with
common system libraries.  libutil (part of libc) is the first, but probably
not the last example that already caused trouble twice.
