As we need hop chains to efficiently navigate to the injection
point on pandaboard, this campaign uses these. As we do not yet
have a component, which automatically navigates to a generic
InjectionPoint (API needs to be properly designed), we do this
explicitly.

As for the pandaboard to navigate fast to the injection
instruction we need to deliver a hop chain to the fail-client,
this commit adds a generic wrapper for a injection point.
For now we have only the two options hop chain and instruction
offset, so it is activated via a cmake ON/OFF switch.

Single-stepping as in tracing sometimes fails in a long step-chain.
So we repeat the step until it really stepped. It can be observed, that
if openocd returns a step error, it never accidently steps nonetheless.
To ensure this behaviour, we could check for correct pc.

As non-gzipped trace-files cause the tool to always import zero events, the
input file is now openend as in the dump-trace tool, where opening non-gzipped
files obviously works fine.

Added opcode parser of the F.E.H.L.E.R-project for analysis of
memory access in mmu-abort handling, tracing, etc.

Added performance monitor hw-function cycle count.
Also fix for single-stepping exit, some additional register
exits and prevention of reboot failures.

Polling of current target system state was done non-blocking until now.
Because of this, when the target was executing a longer time, the main-loop
was walked through several times and so unwanted state changes were
triggered. After this fix, the polling of execution state is blocking
in a while-loop until the target system hits any halting condition.
Also added some minor fixes

Previously for correct termination, the PandaController called
the finish-function of the openocd wrapper, invoked a coroutine
switch and waited for the openocd wrapper to finish up and switch
coroutine again, so the PandaController could exit with correct
exitStatus. Now the openocd-wrapper directly exits with chosen
exit status.

In the OpenOCD config file for omap4460 an old definition of
Cortex-A9 CPUs was used. Without this fix, OpenOCD would not
start up.
Additionally this commit reduces the number of available Cortex-M
debug targets to one for the sake of simplicity.

Normally OpenOCD reads all GP-Registers at halt, which is slow.
Restriction to only necessary Registers 1 and 15.
In the normal use case of OpenOCD this performance reduction does
not matter, because debugging does not need to be optimized for
performance. It just has to be faster than the human perception.
If we need to get the values of the registers 2 to 14, these are
fetched on demand per register.

As the openocd-executable won't be needed, the main-function just
prints a warning, which should never be seen in fail context.

* If included by cpp-file, this will cause trouble. So it gets restricted
to use in c only.
* Prevent usage of "new" as variable name
* No redifinition of true and false, if included by C++
* Definition of bool fixed
Change-Id: Ic5403bd576afd9d2900a8ecfbcfdc50561ba0633
Including
* Main loop for controlling pandaboard
* Modification routines like setting halt conditions, reading
or writing Memory, Registers, etc.
* Timers
The *.hpp file is defined as *.hpp.in, because the absolute path to
config file must be set by CMake-Script (Will be introduced in later
commit)

With the recent updates to record one additional instruction at the trace
start, I broke memory-map handling (restrictMemoryAddresses() and
restrictInstructionAddresses()). This change repairs this functionality.

Listens on a configurable SUT's global variable.
On read access a signal pattern value is calculated and sent back
to the SUT.
Currently, only a superimposable sine wave signal form is implemented.
Further signal forms can be implemented by inheriting from the
abstract SignalForm class.

Add two new breakpoints to L4Sys experiment that allow detecting that
execution terminated with an error: vga_console_blink() is called by the
kernel if JDB was entered (meaning we are hanging, e.g., due to an
assertion); also longjmp() is only used by PF handling code after no
valid page fault handling could be performed

* after injecting a fault, track how many instructions it takes until
execution deviates from original execution
* also track what the first deviating EIP value is

When a register in the extended trace was dereferenced and the value
was smaller than the memory pool size, but the address was not mapped
an assertion occured and the tracing plugin terminated the
simulator. Now the dereferenced memory address is checked for being
mapped and not being smaller than the memory pool.

The ElfImporter is not a real trace importer, but we locate it
into the import-trace utility, since here the infrastructure is
already in place to import things related to an elf binary into
the database.
The ElfImporter calls objdump and dissassembles an elf binary
and imports the results into the database.
Change-Id: I6e35673c8dbee3b7e8dfc7549d10e5dca9b55935
* introduce L4SYS_ADDRESS_SPACE_TRACE to indicate that we want
to trace instructions in a different AS from the one we are starting
the experiment in
* add CR3Run() to determine address space ID
