Hi, In this patch, pending request to backend is calceled when OBEX object is destroyed. Such prevents situations of response on query arriving to destroyed object, e.g. OBEX session is closed in the middle of query to tracker. Such required some changes in phonebook API. More specifcally, changes in API affect phonebook_pull, phonebook_get_entry, and phonebook_create_cache functions. phonebook_req_cancel is added to cancel pending request and deallocate resources respective to it. Phonebook request structure is specific to each backend and created dinamically only for tracker. Therefore phonebook-dummy and phonebook-ebook methods always return NULL instead of pending request. For PBAP, the object holds pointer to pending call. In IRMC, it is session where the pointer is stored and pending call canceled when closing OBEX object, and valid for phonebook_pull only.
