Several database implementations, including, e.g., MySQL and PostgreSQL,
allow multiple rows to be INSERTed at once. At least for MySQL this
improves INSERT speed significantly.

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.

In former versions, the aforementioned image was 'required' to run
gem5 although it wasn't actually used at all. With the new python
script fail_fs.py, it suffices to start gem5 on a target foo.elf by
simply typing $ ../scripts/run-gem5.sh path/to/target/foo.elf

libmysqlclient-dev (or libmariadbclient-dev) is needed to build Fail*.
A running MySQL/MariaDB server to talk to is needed for the
fault-space pruning tools and the DatabaseCampaign, too, but that's a
runtime dependency.

* 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

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"

(Debian 7.1 comes with gcc 4.7.2) However, we are faking a gcc v4.4.5
but the gem5 build system only adds the '-Wno-unused-but-set-variable'
flag in case of a gcc >= v4.6. Now, this flag will always be appended.
(Older gcc versions should ignore the flag or emit a warning but will
continue to run.)

This was necessary because LLVM 3.1's
ELFObjectFile<ELFT>::sectionContainsSymbolsectionContainsSymbol() (needed
for proper functioning of our LLVM disassembler, unless you're using
-ffunction-sections) is "unimplemented".

The random jump importer defines trace events, that indicate all
possible jumps into a specific instruction range. The region where
jumps should start can be defined by a memory map given with
--jump-from. For each instruction declared in that memory range, all
possible jumps to a memory region specified by with --jump-to are
inserted. The target of the jump is saved in the data_address
field. So all database tools work as expected.
for each event E \in region(--jump-from):
foreach Instruction in region(--jump-to):
insert_trace(injection_instr = E.IP(), data_address = Instruction.addr)

The RegisterImporter disassembles the binary and adds a trace event
for each byte read or written from register. The register number (Fail
Register Numbers are used) and the offset within the register are
encoded within the trace event.

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.

- Don't enforce the join order, MariaDB usually gets this right.

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.

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.

BasicImporter is renamed to MemoryImporter. An alias for BasicImporter
in the cmdline interface will remain. The MemoryImporter does now only
handle memory and IP events. The simulation time, dynamic instruction
count and handling of open ECs is moved to Importer.

This importer is so similar to the basic importer, that it can be
dropped. The current state was used in the SOBRES 2013 Paper.
