Added the bit stream reader feature. (#433)

* * rocDecode/ES parser: Added elementary stream file parser for HEVC and AVC.

* * rocDecode/ES parser: Added elementary stream file parser for AV1. Also cleaned up the bitstream ring buffer code.

* * rocDecode/ES parser: Added the IVF container file parser for AV1. Also fixed a bug in fill ring buffer function.

* * rocDecode/ES file parder: Added supported stream type detection.
 - The stream type detection checks the unique syntax patterns of the stream type and calculate the likeliheed score. Based on the score, the most likely type is determined.
 - The current supported stream types are: AVC/HEVC/AV1 elementary streams, IVF AV1 streams.

* * rocDecode/ES file parser: Fixed an AVC decode regression due to a copy and paste error.

* * rocDecode/ES file parser: Added bit depth parsing for codec support check; Added stronger AV1 detection for IVF AV1 stream type.

* * rocDecode/ES file parser: Removed debugging logs.

* * rocDecode/ES file parser: Added exmaple code to use the built-in file parser.

* * rocDecode/Bitstream reader: Renamed the elementary parser feature to bitstream reader and re-organized the code.
 - Moved the bitstream reader code to rocDecode core lib from utility.
 - Added bitstream reader interface in parallel with rocDecode parser and decoder interfaces.

* * rocDecode/Bitstream reader: Added sample to use bitstream reader, instead of FFMPEG demuxer, to get picture data. Also reverted the original sample app back to using FFMPEG demuxer only.

* * rocDecode/Bitstream reader: Renamed the new sample app.

* * rocDecode/Bitstream reader: FFMPEG dependency reduction.
 - Moved MD5 functions out of RocVideoDecoder utility class. This removed RocVideoDecoder's dependency on FFMPEG.
 - Added the new MD5 utility, which depends on FFMPEG lib. MD5 message digest generation is now performed in the MD5 utility.
 - Modified decode sampples that uses MD5 generation function.
 - Removed FFMPEG dependency from video decoder basic sample.

* * rocDecode/Bitstream reader: Added option to use bitstream reader to video decode sample and conformance test script. Added the missing destroy bitstream reader call in video decode basic sample.

* * rocDecode/Bitstream reader: Minor format change. No functional changes.

* * rocDecode/Bitstream reader: Added handling of unsupported stream file type by the bitstream reader to decode sample apps.

* * rocDecode/Bitstream reader: Fixed build errors of several samples.

* * rocDecode/Bitstream reader: Added changes based on review comments.

* * rocDecode/Bitstream reader: File name changes based on review comments.

* * rocDecode/Bitstream reader: Moved MD5 code into single header file. Added changes based on review comments.

* * rocDecode/Bitstream reader: Removed redundant path.

* * rocDecode/Bitstream reader: Changed rocDecode version to 0.10.0. Added minor changes based on review comments.
