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.

v2:
* added comments
* resource_size is not inline anymore
* REGISTER_RESOURCE is a single macro now
* fixed double constructor declaration
* __resource_register renamed to resource_register
* less number of underscores...
