/*******************************************************************************
**
** Function         AVDT_GetAllCapReq
**
** Description      This function initiates a connection to the AVDTP service
**                  on the peer device, if not already present, and gets the
**                  capabilities of a stream endpoint on the peer device.
**                  This function can be called at any time regardless of
**                  whether there is an AVDTP connection to the peer device.
**
**                  When the procedure is complete, an AVDT_GETCAP_CFM_EVT is
**                  sent to the application via its callback function.  The
**                  application must not call AVDT_GetCapReq() or
**                  AVDT_DiscoverReq() again until the procedure is complete.
**
**                  The memory pointed to by p_cfg is allocated by the
**                  application.  This memory is written to by AVDTP as part
**                  of the get capabilities procedure.  This memory must
**                  remain accessible until the application receives
**                  the AVDT_GETCAP_CFM_EVT.
**
** Returns          AVDT_SUCCESS if successful, otherwise error.
