A context atom in ofono represents the active/activating context.  The id is 
managed by the core since the majority of the hardware in this world does it 
like this.  There can be several gprs-context atoms present in a modem at 
once.  So context management inside the gprs context would be extremely 
tricky.

I suggest you store the id in a private struct and let the modem pick you one.  
As long as you notify oFono of context deactivation using the id it gave you, 
everyone is happy.
