android播放http流媒体时默认最低最高缓冲值在4.0.3版本上进行了修改

如题，在2.3.7版本上最低和最高值分别是512K Bytes和5M Bytes.。

enum {
        kPageSize            = 65536,
        kHighWaterThreshold  = 5 * 1024 * 1024,
        kLowWaterThreshold   = 512 * 1024,

        // Read data after a 15 sec timeout whether we're actively
        // fetching or not.
        kKeepAliveIntervalUs = 15000000,
    };

enum {
        kPageSize                       = 65536,
        kDefaultHighWaterThreshold      = 20 * 1024 * 1024,
        kDefaultLowWaterThreshold       = 4 * 1024 * 1024,

        // Read data after a 15 sec timeout whether we're actively
        // fetching or not.
        kDefaultKeepAliveIntervalUs     = 15000000,
    };
