[PATCH v6 09/27] kernel-shark: Start introducing KernelShark 2.0

["Yordan Karadzhov (VMware)" <y.karadz@gmail.com>]

This is the very first patch from a series of patches that will
introduce KernelShark 2.0. The new version will take advantage
of the definition of Data streams and will imply significant
changes in the low level C API, used by the KernelShark GUI. As
a consequence of the API modifications, significant changes are
needed in every source file of the project. Because, we want to
avoid having a huge and ugly single commit that will be extremely
hard to review, we will introduce a regression. We will first
disable the compilation of all sub-components of KernelShark,
except the API itself. This is done by bypassing the search of
the necessary third party components (OpenGL and Qt). Later we
will introduce the changes of the API in several sub-steps and
will re-enable one by one the modified components of the GUI.
