Attempt to provide target listing function (WARNING: this function is actually incomplete)

Browse source 
New issue
Summary: Provide a target listing function
Labels: Milestone-1.4.x
Libnfc lacks of target listing function. Actually, applications or libraries based on libnfc have to wrote their own listing function which can provide side effect if two or more of theses libraries are used together in the same application. Plus, some kind of problem could appears during listing multiples targets (i.e. collisions) and this problem should be solved in libnfc (i.e. using NFC chip capabilities), not in applications based on libnfc.
