OVMS3-idf/components/bt/bluedroid/stack/include/stack/avrc_api.h
Tian Hao adada3f67e component/bt : modify header files to avoid conflict 
1. add the L1 include path with a prefix, such like osi/list.h, stack/a2d_api.h and etc.
2. modify component, only bluedroid/api/include/api is export to another component and application,
   other include path just for bluedroid used
3. put bluedroid/include into common/include/common, so the root directory of bluedroid have no include path.
4. modify doxygen to use esp_bt.h and redirect to
component/bt/bluedroid/api/include/api/

fix compile
