e824e7a0fa cpn: Parsing of unsigned int fixed
As atoi caps the value of a unsigned int bigger than (2^31 - 1) other
than just letting it overflow to the corresponding negative value on
32Bit-integer machines, it must not be used for parsing to unsigned int.

TODO: Also apply this fix to all other unsigned values (in database)
which get parsed by atoi.

8b5098abdd tools: added compute-hops and dump-hops tools
As these tools work closely together with fail components, its
easiest, to build them in this context. As these tools don't
really matter for fail use, they might never be pushed to the
master branch.

c142818325 cpn: Generic wrapper for injection point
As for the pandaboard to navigate fast to the injection
instruction we need to deliver a hop chain to the fail-client,
this commit adds a generic wrapper for a injection point.
For now we have only the two options hop chain and instruction
offset, so it is activated via a cmake ON/OFF switch.

582459c5bb panda: non-returning openocd-loop at terminate
Previously for correct termination, the PandaController called
the finish-function of the openocd wrapper, invoked a coroutine
switch and waited for the openocd wrapper to finish up and switch
coroutine again, so the PandaController could exit with correct
exitStatus. Now the openocd-wrapper directly exits with chosen
exit status.

d26fc28fa4 cpn/database: include data_width in the fsppilot during prune step
During the prune step the data_width of the injected location was not
propagated before. It is now stored in fsppilot (database layout change!) and
sent in the fsppilot protobuf message.

9843b520c1 dbcampaign: select multiple variants/benchmark pairs
The variant/benchmark selection now can use SQL LIKE syntax, all unfinished
pilots from all selected variants are sent to the clients. E.g.:

./cored-voter-server  -v x86-cored-voter -b simple-% -p basic

Will select the fsppilots in the variants:

- x86-cored-voter/simple-ip/basic
- x86-cored-voter/simple-instr/basic

The variant and benchmark information is now sent within the
fsppilot.

6d8b3331d8 doxygen: doc generation fixed
Doxygen skips undesired directories and files now. In addition, the
documentation of the "fail" namespace has been fixed. Note that there
are still several warnings (due to incomplete documentations) in the
Doxygen output.

880e7a81ff comm: ignore SIGPIPE
This prevents client and server from being sent a SIGPIPE (and
terminating) when the other side unexpectedly closes the connection.
It's way easier to handle this condition when checking the write()
return value, than to do anything smart in a SIGPIPE handler.  More
details:

e5fe9dd525 core/sal: interface for backend-specific notion of time
This adds an interface for a backend-specific notion of time, e.g. CPU
cycles since simulator start, and a concrete implementation for the
Bochs backend.  This is needed to record CPU idle times (e.g., HLT
instruction), and for target backends capable of more timing-accurate
execution.

This change also modifies the tracing plugin to add the time to all
trace events.

c24ed774b0 experiments/dciao-kernelstructs: new database driven experiment for DCiAO
The dciao-kernelstructs experiment does a trace imported by the
DCiAOKernelImporter:

   bin/import-trace -t trace.pb  -i DCiAOKernelImporter --elf-file app.elf

Pruned by the basic method:

   bin/prune-trace

and does CiAO fault injection experiments, where the results are
stored in the database.

f18cddc63c DatabaseCampaign: abstract campain for interaction with MySQL Database
The DatabaseCampaign interacts with the MySQL tables that are created
by the import-trace and prune-trace tools. It does offer all
unfinished experiment pilots from the database to the
fail-clients. Those clients send back a (by the experiment) defined
protobuf message as a result. The custom protobuf message does have to
need the form:

   import "DatabaseCampaignMessage.proto";

   message ExperimentMsg {
       required DatabaseCampaignMessage fsppilot = 1;

       repeated group Result = 2 {
          // custom fields
          required int32 bitoffset = 1;
          optional int32 result = 2;
       }
   }

The DatabaseCampaignMessage is the pilot identifier from the
database. For each of the repeated result entries a row in a table is
allocated. The structure of this table is constructed (by protobuf
reflection) from the description of the message. Each field in the
Result group becomes a column in the result table. For the given
example it would be:

    CREATE TABLE result_ExperimentMessage(
           pilot_id INT,
           bitoffset INT NOT NULL,
           result INT,
           PRIMARY_KEY(pilot_id)
    )

7513dacad1 properly deal with clients that talked to another campaign server before
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.

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.

4a4b3ea7e2 FailBochs build process reversed
The FailBochs client is not linked by the Bochs build system anymore, but
by our cmake scripts (make fail-client):
 -  All Bochs libraries are merged into libfailbochs.a (a new target
    within the Bochs Autotools scripts).
 -  The previous libfail.a is *not* a merge of all Fail* libraries anymore,
    but pulls these in via library dependencies.

Additionally I did a lot of build system cleanup, e.g. additional external
libraries may now be pulled in where they're needed.
