443b3e4919 L4Sys: termination shortcuts
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

77b2e208d0 L4Sys Experiment: more on address space tracing
* 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

674af5fd00 Separate boundaries for output tracing and injection
* L4SYS_FUNC_{ENTRY,EXIT} now determines the range upon
  which an experiment is run. These instructions produce the
  output that is relevant for the experiment.

* L4SYS_FILTER_{ENTRY,EXIT} determine a subset of the
  above instructions. FI experiments are performed on this
  subset (between first occurrence of FILTER_ENTRY and first
  occurrence of FILTER_EXIT inclusively).

10420938d2 Rework instruction filtering
Add a new instruction filter that allows filtering a list of
ranges read from a file. This allows us to specify multiple
ranges, e.g., to leave out instructions or to focus on multiple
functions

ed772429f9 L4Sys: fix use of L4SYS_NUMINSTR
* 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.

fd102c01ea Important bugfix: passing the instruction cache entry pointer
does not account for arrays of instructions provided
by one virtual instruction trace cache entry ->
passing the current instruction directly.
ALUInstr not yet completely tested.
