Add a "primary" attribute to provider in the mobile broadband provider info database

[Jason Glasgow <jglasgow google com>]

I've noticed that some providers (e.g. AldiTalk/MedionMobile, blau.de, E-Plus, simyo Internet, NetCologne in Germany, or 3 in Sweden) all share the same set of PLMNs in the mobile broadband provider info (MBPI) database. This means that looking up a provider in the database based on the PLMN yields more than one provider.  After talking to some providers, it appears that in certain instances one can read the SPN file from the SIM card and use this to disambiguate between the different provider entries in the database.

Other carriers though have indicated that sometimes the SPN file on the SIM is empty (or non existent), and in that case one should select the 'primary' or default provider.

I propose that we add an attribute to the provider entity to indicate that it is the 'primary' provider for a given set of PLMNs.

Attached is a patch that defines the attribute and applies it to a few providers.

Thoughts?
