OVMS3-idf/components/bt/bluedroid/stack/a2dp/a2d_api.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.
