Subject: [PATCH] configure.in: convert AC_RUN_IFELSE to AC_CHECK_MEMBERS

With AC_CHECK_MEMBERS, we don't need to compile and run a test program
to check if a daq structure element is defined.

Also check DAQ_Data_Channel_Params_t with params.flags

typedef struct _DAQ_Data_Channel_Params_t
{
    unsigned flags;     /* DAQ_DATA_CHANNEL_* flags*/
    unsigned timeout_ms;/* timeout of the data channel in milliseconds */
    unsigned length;    /* [Future] length of the data associated with the data channel */
    uint8_t* data;      /* [Future] opaque data blob to return with the data channel */
} DAQ_Data_Channel_Params_t;
