[PATCH BlueZ] tools/mesh-cfgclient: Add address checks for pub/sub commands

[Inga Stotland <inga.stotland@xxxxxxxxx>]

This addrs verification of subscriptpion address value entered on
the command line: unassigned address, unicast address, and
all-nodes address are not allowed. Publication address check verifies
that the entered value falls into mesh address space.

Also, change the type of parameter count in comaand processing routines
from int to uint32_t to match the retrun type of the parameter parsing
routine.
