Database::insert_id() retrieves the auto-generated ID from the last INSERT
or UPDATE on a table containing an AUTO_INCREMENT column.

The SConscript in src/core/sal/gem5 is now generated via CMake
(SConscript.in). No more hardcoded relative paths -> Fail* build
folder can now be anywhere. Experiment and Plugin libraries are now
set automagically (using ${EXPERIMENTS_ACTIVATED} /
${PLUGINS_ACTIVATED})
Generated SConscript now resides in binary dir.

* 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.

This commit introduces a virtual dtor in the ArmCPUState class to
prevent the compiler from producing the following warning:
"deleting object of polymorphic class type 'fail::Gem5ArmCPU' which
has non-virtual destructor might cause undefined behaviour"

The InstructionImporter does disassemble the binary and generate read
traces for every instruction byte executed.

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.

The LLVM Disassembler infrastructure can be used to analyze many kinds
of ELF Binaries. For every instruction the used and defined registers
is available as well as information about the instruction itself.

The build system now allows incremental gem5 builds. Unfortunately,
the current solution always requires re-linking the executable.
Without the enforcement of re-linking, the fail code will be rebuilt
but not linked into gem5.
The number of cores for building gem5 is derived from /proc/cpuinfo.
As before, only the gem5.debug configuration is supported.

When recording a "full" trace (register values, plus dereferenced
values), we use a fixed dereference size of 4 bytes.

This does enable % patterns in variant and benchmark selections, like
it is already implemented in the prune-tool.

The correct flags accessor methods should be used to write the flags register,
since values (especially the arithmetic flags) might be cached.

The client sends results back earlier (i.e., before all jobs are
done) if the client response time (CLIENT_JOB_REQUEST_SEC) is
exceeded. This makes sure that extraordinarily long-running
experiments get reported back before, e.g., the LIDO job timeout
kills the Fail* instance.

It is no longer required (and recommended) to write a dependency
check (using conditional compilation) in the experiment code. Instead,
the Fail code performs these checks itself. If an experiment is
compiled without having the required configuration flags set to
enabled, the compiler emits an error. This is because the constructors
of unused listener classes are declared as protected. (Note that
this works only because the Fail code does not create any listeners.)
In a next step, one should remove all the dependency guards in the
existing experiments (not needed anymore).

Quoting connect(3posix): "If connect() fails, the state of the socket is
unspecified. Conforming applications should close the file descriptor and
create a new socket before attempting to reconnect."

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.

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.

The checkpoint which is produced by this save method is a little bit
different to the checkpoint which is produced by the --take-checkpoint
command. It differs in the save-parameters so_state, funcExeInst, intRegs,
_upc, _nupc, _when. Tests have shown that it probably does not affect the
course of the program execution.

The previous implementation wasn't in a working state because
the register content retrieval was buggy. (For example, RT_FP
does *not* denote a "floating point" register. Instead, it is
the frame pointer!)
