reserve: Move get_name_owner() to the public rd_device API

Browse source 
The function is interesting for both rd_device and rd_monitor so make
it part of the rd_device public API to avoid duplicated code.

The decision to move the function to reserve.c is motivated by the fact
that other projects (i.e. jack) use reserve.c only. Therefore, adding a
reserve->reserve-monitor dependency should be avoided.
