euspectre Do not build kedr_trace* and the related stuff by default
kedr_trace.ko was only used in call monitoring - which is actually
unmaintained and should not be used (Ftrace is superior). Let us build
that module and its tests only if someone expicitly enables that or
enables call monitoring support.

Done while investigating #45.

KEDR is a framework for dynamic (runtime and post factum) analysis of Linux kernel modules, including device drivers, file system modules, etc. The components of KEDR operate on the kernel modules chosen by the user. They can intercept the function calls made by the modules and, based on that, detect memory leaks, simulate resource shortage in the system as well as other uncommon situations, etc.

For the present, KEDR is provided for 32- and 64-bit x86 systems.

KEDR can be used in the development of kernel modules, for example, as a component of QA system, as well as when analyzing the kernel failures on a user's system (technical support). Certification systems and other automated verification systems for kernel-mode software can also benefit from it.
