CMake does not support linker groups, which were used to "automatically"
fix circular dependencies between different static FAIL* libraries and
the ordering of dynamic external libraries broke linking.
CMake can however correctly invoke the linker if dependencies are decribed
correctly (even if circular). This required changing all add_dependencies
calls between libraries to target_link_libraries (which creates a link-time
dependency) and linking all experiments to fail-sal.

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.
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.
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
The includes of these headers have already been removed from the experiments. In the current code, the content of the header BochsRegister.hpp is rather simply copied to x86/Architecture.hpp. It is therefore necessary to revisit the code soon (especially the FIXME related to register IDs).
Another problem is that there is no generalization of register IDs. Thus, all experiments are currently specific to a concrete architecture (which is not desired).

Unfortunately, this does not (yet) work as advertised. I need to fight another
round of CMake battles before retrying. Reverting to previous state for now.
This reverts r1753.

ag++ is now called with a list of currently active aspect headers
(ag++ -a aspect1.ah -a aspect2.ah ...). This resolves several problems at
once:
- Build directories may be positioned arbitrarily now, they need not be
a subdirectory of the project anymore.
- Multiple build directories can coexist within the project tree. Before
this commit, the generated instantiate-*.ah aspect headers disturbed
neighboring build trees.
- Due to this, the regression test should be runnable much more easily
now.
- The build time was reduced by an average of about 10%.

This is a precaution to avoid current and future naming conflicts with
common system libraries. libutil (part of libc) is the first, but probably
not the last example that already caused trouble twice.
