Certain internal mechanisms of DPDK access different file system structures (e.g. /sys/bus/pci/devices). It is difficult to test those cases automatically by a unit test when such path is not hard-coded and there is no simple way how to distribute fake ones with the current testing environment. This patch adds a possibility to declare a resource embedded in the test binary itself. The structure resource cover the generic situation - it provides a name for lookup and pointers to the embedded data blob. A resource is registered in a constructor by the macro REGISTER_RESOURCE. Some initial tests of simple resources is included and added into the group_1. Signed-off-by: Jan Viktorin <viktorin@rehivetech.com>
