[PATCH 5/7 v3] Add support for notyfying pbap about more parts from backend

[Radoslaw Jablonski <ext-jablonski.radoslaw@nokia.com>]

Added new parameter to phonebook_cb - lastpart variable.
If backend want to notify that more parts of current
request will be delivered later, it should use lastpart=FALSE.
Because of that, PBAP core will 'know' that should not finalize
request immediately after receiving data and wait for more
parts to come.
If result is returned in one part and no more responses part
will be sent later, then backend should use lastparam=TRUE.
Previously results of request from backend was always returned
in one part to PBAP core.
