- specify "proto2" syntax for protobuf messages
- minor build-system and C++ namespace fixes

d0d62de3f4 sal: remove perf dependency to watchpoints/breakpoints
This change removes the hard compile-time dependency from the
performance-improving dedicated listener-list implementation
(core/sal/perf/) to basic watchpoints / breakpoints being enabled in
the cmake config.  This allows to keep the CONFIG_FAST_* switches
enabled in practically every experiment.

The primary reason for this change was the recent insight that enabled
breakpoints with disabled CONFIG_FAST_BREAKPOINTS can massively slow
down an experiment even if the latter does not use a single breakpoint
itself.

da3a78ec4d faultspaceplot: fix ymin calculation
The initialization value for ymin, which tracks the lower bound of
plotted rectangles (and is finally used for the preselected zoom
area), was chosen too small for Linux-kernel data structure addresses.

recent Linux version: "mode sense" command executed in DMA mode).
Updated output of "mode sense" page 0x2a (still reporting CD-ROM
drive)."

a2798cc2bf bochs: backport PCI IDE buffer-overflow fix
Upstream SVN r10244: "Fixed possible buffer overflow causing segfault
or memory corruption. The buffers are not large enough for the maximum
sector count in LBA48 mode. Now resetting buffer pointers after
processing a PRD (and move remaining data if necessary). This should
fix the SF bug items #3190970 and #3077616."

This happened to us when booting Debian 8 with a Linux 3.16 kernel
from "flat" or "volatile" disk images, in the end corrupting the VGA
card's ("theVga") internal state and segfaulting.

de8598ab83 cmake: prefer LLVM 3.4 over system-wide default
FindLLVM.cmake now starts searching for specific "llvm-config-x.y"
versions instead of using the system-wide default "llvm-config" first.
This avoids breaking builds on Debian 8, where LLVM 3.5 is the (yet
unsupported) default, but 3.4 is still installable.

39b120f7ca GenericExperiment: record output during complete runtime
Before this change, the GenericExperiment only recorded port 0xe9 output
*after* the fault was injected.  When a fault was injected during the
workload's output loop, the output data before that point in time was
missing, and the experiment outcome was wrongly classified as SDC.

This change moves the logging activation to before the fast-forwarding
step (DatabaseExperiment::cb_before_fast_forward).  It also makes sure the
DatabaseExperiment only clears its own listeners instead of also touching
the SerialOutputLogger's one.

5bd7c4a9c5 GenericExperiment: limit output logger buffer
Limit the serial-output logger buffer to prevent overly large memory
consumption in case the target system ends up, e.g., in an endless loop.
The buffer is limited to (golden-run output size)+1 to be able to detect
the case when the target system makes a correct output but faultily adds
extra characters afterwards.

maxima_data, l_mem_outerspace never matched in the
generic-experiment's "--catch-write-outerspace" mode.

ee8759f6b8 faultspaceplot: don't round down ymin
Before this change, ymin was rounded down to the nearest Y value
divisible by 1000, showing an empty, white area in the lower part of
the plot.  With this change, the initial Y-axis zoom level is
maximized to exactly show all non-white areas.

e8ca3ba6ea faultspaceplot: don't plot OK_MARKER
In the current configuration, OK_MARKER would be plotted in white
color and be indistinguishable from the background.  Not plotting
these areas at all reduces output-file size.  As a side effect, the
initial Y-axis zoom level (ymin, ymax) can change.

to generic-experiment.

 -  The latest AspectC++ nightlies should work without any

bfcb1b415b experiments: experiment for tracing and testing ERIKA
ERIKA Enterprise is a OSEK conforming embedded RTOS. The supplied tracer
and experiment are similar to the cored-{tracing,tester} experiment, but
checks the integrity of the RTOS application in a different
manner. Stacks and stackpointers are located differently in ERIKA. This
experiment was used in RTAS'15 Hoffmann et al.
