Renamed `MMCommonSimpleProperties' to `MMSimpleStatus', and removed the
`MMSimpleStatusProperties' provided in libmm-glib. We'll just use the original
one from libmm-common always.

Renamed `MMCommonLocation3gpp' to `MMLocation3gpp', and removed the
`MMModemLocation3gpp' provided in libmm-glib. We'll just use the original one
from libmm-common always.

Renamed `MMCommonConnectProperties' to `MMSimpleConnectProperties', and removed
the `MMModemSimpleConnectProperties' provided in libmm-glib. We'll just use the
original one from libmm-common always.

Equivalent to `PinRetryCount' in the previous API. We don't have an additional
property for the retry count of the current lock, as it really is duplicating
information.

ModemManager will load:
  1) The list of supported bands. Note that this doesn't mean that any possible
     combination of bands is supported, as modems may support only specific
     combinations, but at least gives a rough idea of what the modem is capable
     of handling.

  2) The list of CURRENT bands. There is no such "Allowed" bands, as we do with
     modes, modems will have a specific set of bands being currently used, which
     will be reported in the `Bands' property.

If the modem allows modifying the list of bands to use, this can be done with
the `SetBands()' method. If the modem doesn't support using a specific
combination of bands, this method will report an error.
