make possible to reload dynamic libraries without stopping the
DeploymentComponent

Motivation. imagine that you have a producer and a consumer launched by a
DeploymentComponent.
You have detected an error in the component and you want to overwrite a new
version of the file. You will overwrite component.so (of course you need to
"kickOut" the consumer first) and you want the update to take effect when you
start everything again.
The attached patch make possible to detect if a loaded library can be unloaded
and loaded again. We have to check if thereisn't any instance of any Component
loaded from the dynamic library that we are trying to reload.
