When running SPDK application on a given set of
CPU cores, create lock files for each of them.
This wil prevent user misconfiguration and
assigning a core to more than one SPDK instance.
The introduced mechanism is based on device locks
implemented in spdk_pci_device_claim() function.
Add a command line option to disable lock files.
This feature will be useful in cases where differing
CPU cores is impossible (eg. setup with only one core
available).
The patch also fixes all existing cases of overlapping
core masks.
