According to
<http://dev.mysql.com/doc/refman/5.5/en/c-api-threaded-clients.html>,
(potentially) threaded clients should use the reentrant
libmysqlclient_r. This is just a precaution, I haven't seen any
issues with the normal libmysqlclient.

According to
<http://dev.mysql.com/doc/refman/5.5/en/c-api-threaded-clients.html>,
a MySQL connection handle must not be used concurrently with an open
result set and mysql_use_result() in one thread
(DatabaseCampaign::run()), and mysql_query() in another
(DatabaseCampaign::collect_result_thread()). This indeed leads to
crashes when bounding the outgoing job queue (SERVER_OUT_QUEUE_SIZE),
and maybe even more insidous effects in other cases. The solution is
to create separate connections for both threads.
Additionally, call mysql_library_init() before spawning any threads.

Up until now the JobServer was silently losing jobs and only claiming to be
finished - a workaround for this was to restart the campaign until all jobs
were finished according to the database and the campaign's output.
This change fixes the underlying problem, so a single campaign-run suffices
and does no longer lose any jobs.
Debugging this was awful and took us quite some time...

This removes the ability to directly parse protobufs from the socket, because
google::protobuf::Message::ParseFromFileDescriptor() needs a EOF after each message;
thus preventing us from sending multiple Message objects over a single socket.

GEM5 throws a reset trap during initialization.
This happens before the startup function is called.
This leads to problems because the startup function fills the m_CPUs list.
m_CPUs is needed for the TrapListener.
Therefore, we only react on traps after initialization.
This is needed in the following commit (see gem5/src/arch/arm/faults.cc).

In the OpenOCD config file for omap4460 an old definition of
Cortex-A9 CPUs was used. Without this fix, OpenOCD would not
start up.
Additionally this commit reduces the number of available Cortex-M
debug targets to one for the sake of simplicity.

Normally OpenOCD reads all GP-Registers at halt, which is slow.
Restriction to only necessary Registers 1 and 15.
In the normal use case of OpenOCD this performance reduction does
not matter, because debugging does not need to be optimized for
performance. It just has to be faster than the human perception.
If we need to get the values of the registers 2 to 14, these are
fetched on demand per register.

As the openocd-executable won't be needed, the main-function just
prints a warning, which should never be seen in fail context.

"removed" unneccessary memory-mapping ("Step 0")
cleaned out ExperimentData - now consists only of fsppilot and resultset
resultset now contains bitoffset which is part of result-table's primary key

Although we know that a known_outcome=1 pilot does not exhibit
behavior different from the golden run, the database schema does not
yet know what this behavior looks like (in terms of result-table
column values). In order to be able to JOIN valid results for all
memory writes in the trace table (fspgroup maps them all onto *one*
pilot per variant), we need to run these experiments, too.
Additionally, don't join the fspgroup table; we only need this one for
result calculations afterwards.

As non-gzipped trace files cause import-trace to always import zero
events, the input file is now openend as in the dump-trace tool, where
opening non-gzipped files obviously works fine.
In the medium term we should find a centralized solution for this,
instead of re-implementing it all over the place.

* If included by cpp-file, this will cause trouble. So it gets restricted
to use in c only.
* Prevent usage of "new" as variable name
* No redifinition of true and false, if included by C++
* Definition of bool fixed

Including
* Main loop for controlling pandaboard
* Modification routines like setting halt conditions, reading
or writing Memory, Registers, etc.
* Timers
The *.hpp file is defined as *.hpp.in, because the absolute path to

commit)

With the recent updates to record one additional instruction at the trace
start, I broke memory-map handling (restrictMemoryAddresses() and
restrictInstructionAddresses()). This change repairs this functionality.

Listens on a configurable SUT's global variable.
On read access a signal pattern value is calculated and sent back
to the SUT.
Currently, only a superimposable sine wave signal form is implemented.
Further signal forms can be implemented by inheriting from the
abstract SignalForm class.

Add two new breakpoints to L4Sys experiment that allow detecting that
execution terminated with an error: vga_console_blink() is called by the
kernel if JDB was entered (meaning we are hanging, e.g., due to an
assertion); also longjmp() is only used by PF handling code after no
valid page fault handling could be performed

When a register in the extended trace was dereferenced and the value
was smaller than the memory pool size, but the address was not mapped
an assertion occured and the tracing plugin terminated the
simulator. Now the dereferenced memory address is checked for being
mapped and not being smaller than the memory pool.

The ElfImporter is not a real trace importer, but we locate it
into the import-trace utility, since here the infrastructure is
already in place to import things related to an elf binary into
the database.
The ElfImporter calls objdump and dissassembles an elf binary
and imports the results into the database.
