Both the ModemManager daemon and the mmcli will now include `libmm-glib.h' only.
We also handle two new special `_LIBMM_INSIDE_MM' and `LIBMM_INSIDE_MMCLI'
symbols, which if included before the `libmm-glib.h' library allow us to:
* Don't include the libmm-glib high level API in the ModemManager daemon, as
the object names would clash with those in the core.
* Define some of the methods of helper objects to be included only if compiling
ModemManager daemon or the mmcli.
The user can now query for all location information with
`mm_modem_location_get_full()', or just for specific location sources with
`mm_modem_location_get_3gpp()', `mm_modem_location_get_gps_nmea()' or
`mm_modem_location_get_gps_raw()'.
Renamed `MMCommonLocation3gpp' to `MMLocation3gpp', and removed the
`MMModemLocation3gpp' provided in libmm-glib. We'll just use the original one
from libmm-common always.
