wangmengyang 30198ee8c1 component/bt: add new example for A2DP 
1. add new example for A2DP and the related btif layer source code is ported
2. modification on osi_alarm_new API to support periodic timer
3. enable macro BTA_AR_INCLUDED, BTA_AV_INCLUDED, BTA_AV_SINK_INCLUDED
4. The A2DP example cannot work and can only be built successfuly
