OVMS3-idf/components/bt/bluedroid/stack/avrc/avrc_sdp.c
Yulong 63e5cbbd66 component/bt: Added the bluedroid environment variable dynomic malloc support & support to malloc the memory to the psram. 
component/bt: Added the Macro for the classic BT support.
component/bt: added the bluedroid deinit method.
component/bt: allow more classic BT global variables to use dynamic allocation scheme
1. allocate memory for AVDT, AVCT control blocks when dynamic memory is used
2. allow SBC decoder buffer to use dynamic allocation scheme
component/bt: Remove the wrong changes in bt/Kconfig & Added the GATTS_INCLUDED in the gatt_free function when gatt service close.
component/bt: Shorten the abbreviation BT_ALLOCATION_FROM_SPIRAM_FIRST and BT_BLE_DYNAMIC_ENV_MEMORY two macros.

** UUID of the search. Then retrieves various parameters
** from the record. When it is finished it calls the

** 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.

** perform the service search.
