[PATCH 0/6] Add oFono DUN emulator

[Zhenhua Zhang]

Hi,

This series are the initial patches for ofono DUN emulator.

1. src/emulator.c handles emulator create, remove, enable, disable and etc..
2. plugins/dun_gw.c is the plugin similar to hfp.c. It's the interface with BlueZ serial DUN agent.
3. gatchat/test-emulator.c is the test case to test emulator without BlueZ interface.

Emulator driver is registered statically once ofonod starts up. It probes BlueZ adapter properties to create emulator on active modem that having GPRS interface.

Thanks,
Zhenhua
