We want to expose in the Modem interface the list of supported IP families, and
the easiest way to do so is to have the IP family as flags, and provide in the
interface a single enum.
Also, a value of 0 for a MMBearerIpFamily specifies that no flags are set, so
just rename it to 'NONE'.
And add a new 'ANY' value which sets all flags to 1.
Specifying 'none' is really not exclusive. We may want to say that the modem can
either authenticate with a given protocol, or otherwise just try without
authentication.
The reality is that 'none' itself is usually always given in the connection
settings.
For bearers using STATIC or DHCP IP method, the modem itself is the one
negotiating authentication with the network. The new `allowed-auth' property
allows users to specify which authentication method(s) are allowed to be used.

It's pointless to have libmm-common around, just merge it into libmm-glib and
make ModemManager depend on libmm-glib directly. At the end, the non-common
stuff in libmm-glib is really minimal.
