/*
*    main.c
*
*    mbtk_rild main file.
*
* The main functions are as follows:
* 1. Execute boot script /etc/init.d/mbtk_boot_server_ready after AT is ready(Only execute one time).
* 2. Execute boot script /etc/init.d/mbtk_boot_net_ready after network is ready(Only execute one time).
* 3. Set the frequency band based on the relevant information in the "device_info" partition.
* 4. Create socket server(The client implementation in API).
* 5. Create 3 connections between atcmdsrv, related devices: /tmp/atcmd_at ,
*                           /tmp/atcmd_at_1 , /tmp/atcmd_at_2
