To: refpolicy
The wpa_cli application has two functions within the network manager
environment: (1.) it acts as a commandline interface for administrators
to interact with wpa_supplicant, and (2.) it gets called from within init
scripts to perform some administrative, unattended tasks.
In this patch, we mark the wpa_cli_t domain as an application domain, introduce
a few interfaces to allow roles to run the wpa_cli application, and enhance the
wpa_cli_t local policies to reflect its dual use.
