Synopsis
========
This CR implement Pass through feature for producer.

Branch : PRODUCER_14_0_RN
Suggested by Sujeet

Description:
==========
The most of IP camera support H.264 video encoding from the camera. In this case, HMP \
doesn't need to transcode it again.  It saves system resource and content quality.  \
If RTSP stream source has H.264/AAC codec, HMP pass through encoded data.

This CR support pass through all input stream at the same time. This CR never support \
pass through one stream and encoder another stream.

My solution:
1 Add two option in input: "PassThroughVideo" and "PassThroughAudio", their default \
value are false. Customer can set PassThroughVideo=true and PassThroughAudio=true to \
enable pass through. If the input video stream is h.264 and audio stream is AAC, and \
the PassThroughVideo and PassThroughAudio are true, HMP will pass through the input \
stream.

2 If pass through is enable, HMP will create a pass through pipeline, like the \
following:

Input filter(Dtdriver-> depacketizer->dtdrreader) ==>packetizer filter==> packetizer \
asm mux filter ==> destination filter(rbs)

Input filter(Dtdriver-> depacketizer->dtdrreader) ==>unpacketizer asm mux filter ==> \
destination filter(file write)

3 Implement audio depacketizer and video depacketizer plug-in so that Dtdriver \
plug-in can depacketizer H264 and AAC stream. 264depacketizer.rar and \
aacdepacketizer.rar are source code of the new depacketizer plug-in. Path of the two \
plug-in are: datatype\mp4\audio\aacdepacketizer.
datatype\mp4\video\264depacketizer.

4 Implement new class CAudioSourceDepacketizer in source file adepacker.cpp and \
adepacker.h. Dtdriver plug-in will through class CAudioSourceDepacketizer to search \
audio depacketizer plug-in, and depacketize input stream.

5 I add a new macro HELIX_FEATURE_PASS_THROUGH into source file h264pyld.cpp and \
mp4apyld.cpp so that Passthrough feature can share source file with other feature. I \
define macro HELIX_FEATURE_PASS_THROUGH at Umakefil of 264depacketizer folder and \
aacdepacketizer folder.

Testing Performed:
================
Unit Tests:
1. enable pass through by set PassThroughVideo="true", PassThroughVideo="true"
Input: only one audio stream, type is AAC.
Output: save as a MP4 file.
Expected: HMP never decode and encode the input stream, just pass through it.
Real result: Yes

2. enable pass through by set PassThroughVideo="true", PassThroughVideo="true"
Input: only one video stream, type is  H264.
Output: save as a MP4 file.
Expected: HMP never decode and encode the input stream, just pass through it.
Real result: Yes

3. enable pass through by set PassThroughVideo="true", PassThroughVideo="true"
Input: two input stream, video is H264, audio is AAC
Output: save as a MP4 file.
Expected: HMP never decode and encode the input stream, just pass through it.
Real result: Yes

4. enable pass through by set PassThroughVideo="true", PassThroughVideo="true"
Input: two input stream, video is H264, audio is AAC
Output: RBS.
Expected: HMP never decode and encode the input stream, just pass through it to \
server. Real result: Yes. But there are some warning message.

5. disable pass through by set PassThroughVideo="false", PassThroughVideo="false"
Input: two input stream, video is H264, audio is AAC
Output: save as a MP4 file.
Expected: HMP will decode and encode the input stream.
Real result: Yes
