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

Without --with-all-libs (as documented in doc/how-to-build.txt), at least
the "nogui" GUI does not work anymore -- the default for headless
experiments.
(Note the UNDEFINED->UNDEF enum rename; this was necessary due to a vga.h
include side-effect in bochs/gui/svga.cc.)

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").

It doesn't make sense to override database, hostname or username parameters
coming from ~/.my.cnf with arbitrary own defaults. Instead allow
libmysqlclient to use the builtin default parameter mechanism.
See <https://dev.mysql.com/doc/refman/5.1/en/option-files.html> for what a
~/.my.cnf may look like; example:
[client]
user=hsc
password=secret42
database=fail_demo

Imported and adapted FindProtobuf.cmake from cmake 2.8.9 into the project to
make it build on Debian 6 again.

The import tool does support the following import strategies:
- BasicImporter: generates def-use equivalence classes for read and
write memory accesses
- DCiAOKernelImporter: generates equivalence classes for read access in
the ciao kernel space.

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.

The T32 can simulate bare instruction sets without periphery.
For the Cortex-M3 we have complete NVIC model including Systick Timer.
Currently a simple CiAO can run on the simulator.
TODO:
- Let memlogger log all memory accesses.
- Interact with FailT32 for a complete simulation/FI
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.
If CommandLine.hpp and (indirectly) optionparser.h is #included in
FailBochsInit.ah, bochs compilation fails (for, e.g., gui/x.cc, at least
on Debian 6).
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
