ModemManager/src/mm-iface-modem-simple.c
Aleksander Morgado 793370f2f8 api,bearer: new 'profile-id' setting 
We define a new 'profile-id' setting in the bearer properties that
users will use to specify which connection profile of the ones
available in the device should be connected.

When the 'profile-id' is given, the associated bearer object will be
bound to the 'profile-id', and the user is able to provide additional
settings to apply on top (e.g. if the profile storage doesn't allow
some of the settings we support, like 'apn-type', or if the setting is
completely unrelated to profiles, like 'multiplex').

After introducing the 'profile-id' as a valid setting in the bearer
properties, we also reimplement the properties object internals to
make use a 3GPP profile for the subset of common settings between both
objects.
