Tian Hao e4f63819a1 component/bt : remove all GKI reference 
1. remove GKI(not use osi_free_and_reset)
2. modify mutex/semaphore to individual directory
3. set osi_malloc as malloc(previously use calloc)
4. change osi allocator debug osi_free
5. fix rebase of remove GKI

** finds the first record in the database that matches the
** UUID of the search. Then retrieves various parameters
** from the record. When it is finished it calls the
** application callback function.

** Returns Nothing.

** Function AVRC_FindService
**
** Description This function is called by the application to perform service
** discovery and retrieve AVRCP SDP record information from a

** record found on the server that matches the service UUID.
** The callback function will be executed when service discovery
** is complete. There can only be one outstanding call to
** AVRC_FindService() at a time; the application must wait for
** the callback before it makes another call to the function.
** The application is responsible for allocating memory for the
** discovery database. It is recommended that the size of the
** discovery database be at least 300 bytes. The application
** can deallocate the memory after the callback function has
** executed.
**
** Input Parameters:
** service_uuid: Indicates TG(UUID_SERVCLASS_AV_REM_CTRL_TARGET)
** or CT(UUID_SERVCLASS_AV_REMOTE_CONTROL)
**
** bd_addr: BD address of the peer device.
**
** p_db: SDP discovery database parameters.
**
** p_cback: Pointer to the callback function.
**
** Output Parameters:
** None.
**
** Returns AVRC_SUCCESS if successful.
** AVRC_BAD_PARAMS if discovery database parameters are invalid.
** AVRC_NO_RESOURCES if there are not enough resources to
** perform the service search.
