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

* L4SYS_FUNC_{ENTRY,EXIT} now determines the range upon
which an experiment is run. These instructions produce the
output that is relevant for the experiment.
* L4SYS_FILTER_{ENTRY,EXIT} determine a subset of the
above instructions. FI experiments are performed on this
subset (between first occurrence of FILTER_ENTRY and first
occurrence of FILTER_EXIT inclusively).

Add a new instruction filter that allows filtering a list of
ranges read from a file. This allows us to specify multiple
ranges, e.g., to leave out instructions or to focus on multiple
functions

* L4SYS_NUMINSTR counts the instructions that were selected for
injection and is used by the campaign server to generate experiments
* L4SYS_TOTINSTR counts the total number of instructions executed.
It is used by the experiment to determine the timeout value.

* mention how to obtain an L4Re setup
* describe finding the address space identifier in more detail

- Don't enforce the join order, MariaDB usually gets this right.
- Update DB statistics before terminating.

The previous fault injection experiment was kind of bullshit. This one
is better in several ways:
- sanity check at injection time (correct IP)
- correct counting of kernel_transistions
- copy whole activation scheme

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.

It is a simple and short experiment that performs single stepping
through the target. It is designed to be used with gem5 (+ ARM).

We're not yet using the common DatabaseCampaign as it doesn't allow
for additional experiment parameters (such as "variant" and
"benchmark") yet. TODO: Integrate changes in DatabaseCampaign in a
generic way and use it.

When eCos is built as a multiboot binary, some of its data structures
are still at very low (<<1M) addresses, but the rest moves to
addresses >1M. This change makes sure our invalid mem access
detection is not overly generous.

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.

This allows us to generate prerequisites (traces, state snapshots, memory
maps) in parallel, and without the previous shell script hacks.

After each simulator break, T32Tracer retrieves the latest (16)
trace records from the T32. Memory address and value can now
be evaluated easily from the trace record.
TODO:Nevertheless we still have to traverse the trace to
find the instruction causing the access.
The full-tracing plugin was used in the DSN paper. It additionally
traces the data that was accessed/written on a memory access and the
contents of some CPU registers.

An experiment talking to a campaign server via the JobClient/JobServer
interface needs the FailControlMessage.proto compiler to run before the
experiment is compiled. A dependency on fail-comm ensures this.
For the T32 variant we have to evaluate the memory
access instruction to find out, which memory address
was accessed.
Dissassmbly by OpenOCDs arm_disassembler.hpp/.cc:
- fine for ARM / Thumb1
- needs fixes for Thumb2 :( (currently doing that..)
The disassembler disassembles an elf file with
an external objdump tool.
The architecture specific objdump must be configured
via cmake (ARCH_TOOL_PREFIX), e.g. arm-none-eabi- for
arm-none-eabi-objdump.
- getSection/getSymbol now returns an ElfSymbol reference.
Searching by address now searches if address is within
symbol address and symbol address + size.
So we can test, if we are *within* a function, object or
section and not only at the start address.
Currently working:
- Connect/Disconnect, Read CPU info
- CMM Script generation and T32 startup via cmake (make runt32)
- Read/Write Register, Read Program Pointer
- Read/Write Memory
- Single Breakpoint
- Setting Memory Breakpoint
TODO:
- Fix mock aspect for T32_GetRam.
- Fix Thumb2 bit in function addresses from ELFReader
- Evaluate memory breakpoint hit
