jeffqjiangNew 9e64945bdf Fixed several issues with cropping. (#275 )

* * rocDecode: Fixed several issues with cropping.
  - Fixed the pixel start offset error on streams with non-zero top/left cropping in MD5 calculation.
  - Fixed the pixel start offset error on streams with non-zero top/left cropping, and/or with user specified cropping in YUV frame output.
  - Sorted out code which deals with cropping area specifiied by the bitstream, and cropping area specified by the user.

* * rocDecode: Additional changes after discussion.
 - Set display rect for decoder create/reconfig to displayable area or user specified ROI area.
 - Do not set target rect for decoder create/reconfig. Leave it for future use.
 - Unified naming of display rect in decoder create/reconfig structs.

* * rocDecode: Put back the extra rounding to target width/height specifiied by the coded stream, for peace of mind, based on code review.

* * rocDecode: Added the missing stream specified cropping offset to the starting pixel pointer for none-internal memory modes.

Video decode multi files sample

The video decodes multiple files sample illustrates the use of providing a list of files as input to showcase the reconfigure option in the rocDecode library. The input video files have to be of the same codec type to use the reconfigure option but can have different resolutions or resize parameters.

The reconfigure option can be disabled by the user if needed. The input file is parsed line by line and data is stored in a queue. The individual video files are demuxed and decoded one after the other in a loop. Output for each input file can also be stored if needed.

Prerequisites:

Install rocDecode
FFMPEG
- On Ubuntu
```
sudo apt install ffmpeg libavcodec-dev libavformat-dev libavutil-dev
```
- On RHEL/SLES - install ffmpeg development packages manually or use rocDecode-setup.py script

Build

mkdir video_decode_multi_files_sample && cd video_decode_multi_files_sample
cmake ../
make -j

Run

./videodecodemultifiles -i <input file list[required - example.txt]>
                        -d <GPU device ID - 0:device 0 / 1:device 1/ ... [optional - default:0]>
                        -use_reconfigure <flag (bool - 0/1) [optional - default: 1] set 0 to disable reconfigure api for decoding multiple files. Only resolution changes between files are supported when reconfigure is enabled. The codec, bit_depth, and the chroma_format must be the same between files>

Note: Example input file list - example.txt

infile input1.[mp4/mov...] [required]
