Before this change, running prune-trace with, e.g.
"prune-trace -d fsp_mibench -v bitmap% --benchmark-exclude clockcnv"
resulted in an implied "--benchmark none", rendering --benchmark-exclude
ineffective and resulting in nothing being pruned. Now, the "none" default
only applies when neither --benchmark nor --benchmark-exclude (analogously
for --variant / --variant-exclude) is provided.

In some cases the write-pilot is located at the upper boundary of the
experiment and thus is in a race situation with the experiment's end.
If the experiment's end occurs first, the campaign ends and complains
about missing data, otherwise everything is fine.
This patch circumvents this via using "the first" writing pilot; iff the
only write is located at the experiment's end, the race will still occur,
but cleverly written experiment code can, according to hsc, circumvent it.

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.

There's one fspgroup entry for every trace entry, the pilot_id is
therefore *not* part of the (unique) primary key. If this had been
right in the first place, it would have revealed an equivalence-based
fault-space pruning bug early ... :-/

This change introduces a CMake-style FindMySQL.cmake properly looking for
libmysqlclient_r with mysql_config. This also fixes linking on some
machines.

data_address is definitely part of the unique key to trace entries, but
instr2 is arbitrary (could be instr1, time1 or time2 as well). Moving
data_address up the hierarchy to speed up certain FSP experiments.

Is now very similar to normal importer, and may be deleted in the future, but
at the moment, this should be merged, since it is the importer used in the
sobres-2013 paper.
This changes the MySQL Schema. instr1_absolute was introduced.

- Variants/benchmarks can now be selected with wildcards
(--variant/--benchmark), and can be excluded from pruning
(--variant-exclude/--benchmark-exclude).
- The database clearing step can be skipped with --no-delete to
avoid deadlocks with concurrent DB accesses.
- Internals:
* injection_instr / injection_instr_absolute moves from
fspgroup to fsppilot. fsppilot now contains all information we
need for running FI experiments.
TODO: generic campaign needs to be modified, too.
* Force MySQL to use an efficient join order (STRAIGHT_JOIN).

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.

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)
)

This tool creates the fault-space pruning pilot and group
entries. Those are used by the generic campaign to do fault
experiments.
Currently prune-trace only implements conventional def/use pruning
(--prune-method "basic").
