libstagefright: Use LOG_BASIC when use chromium http stack

When using chromium http stack, the LogLevel is LOG_ALL, and
in chromium_net, LOG_ALL will HexEncode all received data. thus
playing a 10Mbps 1080P video stream  will generate 20Mbps Hex Buffer
for event logging. This is a heavy operation for logging.

Store rtsp accessunit until PLAY response parsed

If RTP accessunit comes earlier than play response,
the normal play time mapping posted in func onAccessUnitComplete is wrong.
This leads wrong timestamp of the first few frames.
This issue is found in the 3 CtsVerifier RTSP streaming cases.

Prevent double disconnects in RTSPSource

Prevent a null pointer from occuring by checking that we are not
already disconnected before performing a disconnect, in case
multiple disconnects have been issued.

Prevent Media Server crash while the AwesomePlayer getBitrate return true with mBitrate equals to zero.

[Cause]
   - getBitrate(int64_t *bitrate) will return true if mBitrate = 0.
   - Then, in getCachedDuration_l(int64_t *durationUs, bool *eos), 
     we might execute the following function when 
     getBitrate(&bitrate) = true and bitrate = 0.
        *durationUs = cachedDataRemaining * 8000000ll / bitrate;
   - Mediaserver will be crashed when divided by zero.
   - The mediaserver crash often occur when DLNA IOP tests on Golden DMS
     with AAC_ADTS_320 audio.
[Solution]
   - Prevent the divide function executing when bitrate is zero.
