libmm-glib,3gpp-profile: new 3GPP profile helper object

Define a new helper object which we're going to use to implement the
new profile management interface.

The 3GPP profile object provides the list of settings that modems may
be able to store in their profile list, e.g. "apn", "ip-type" and so
on. Not all modems will be able to support all the settings defined in
the profile object, and therefore, when looking for a specific 3GPP
profile object with a given set of settings, we must make sure we only
compare those settings that are supported by the modem.

The profile management implementation will be able to load during
runtime a set of "compare flags", specifying which settings should not
be checked during the comparison. E.g. a generic AT-based modem that
supports only "apn" and "ip-type" will be compared with the
NO_APN_TYPE and NO_AUTH flags; and an AT/Icera-based modem (which
supports auth settings) will use only NO_APN_TYPE.

The settings in the 3GPP profile should be considered a subset of the
bearer properties.
