Branch tracer (MSR_DEBUGCTLA)

We need a driver for 32 and x64 bit Windows XP and W7 with the following requirements: - Sets the BTF flag (MSR_DEBUGCTLA) for specific processes (configurable) - Hooks int1 and catches, handles the single steps on branches - Inside the int1 handler: for all CTI instructions which modify the stack, the stack values are extracted and logged to disk
