This pull request contains:

• The edits to merge all code into a single repository (i.e. remove all submodules)
• A preliminary CLI implementation

The basic command line is as follows:

Utils/Process_cli.php <url> [options]

With url the URL of a stream, and options can be - at this time - one or more of:
DASH - Common dash mpd checks
DASH-IOP - DASH-IF Interoperability checks
DASH-IOP-LL - DASH-IF Low Latency checks

The script outputs JSON in a custom format to stdout, the format itself is preliminary and might change during the next couple of weeks, depending on what we find.

Had to address a couple points to get this going:

• working directory has to be ./Utils, otherwise imports will fail and function will be undefined
• Conformance-Frontend/temp/ needs to be created, so temporary file can be created/removed in there
• use php7.4 when running with docker image/Ubuntu, since there is no php7 command there

Then I was able to test this by building a new docker image and running it like e.g.:

docker run --rm -w="/var/www/html/Utils" --entrypoint="" dash-if-conformance php7.4 ./Process_cli.php https://dash.akamaized.net/akamai/bbb_30fps/bbb_30fps.mpd DASH

This overwrites the original apache webserver entrypoint and runs the CLI impl instead.

I didn't notice a difference in the JSON output with regards to running differents tests i.e. ´DASH´ vs DASH-IOP or DASH-IOP-LL. Is that expected? If so, I'd go ahead and merge this with the hints from above added to README.md.

I have addded some new commits, @aldafu can you recheck?
Main items;

• Extra checks for HbbTV/DVB
• Switch to php7.4 in the CLI script in order to be compatible with the docker image.
• CLI now has 'normal' parsing, use -h to see all current options.

lgtm @Phencys, runs much more stable.

Couple of questions/things I noticed

• Are the default tests always done? Talking about Xlink resolving, MPD validation and Schematron validation as shown on web interface
• Overall verdict seems to be null when module tests are successful, ie PASS (tested with https://media.axprod.net/TestVectors/Cmaf/clear_1080p_h264/manifest.mpd)
• Do all additional tests run yet? JSON output for e.g. -w or -c returned with an empty entries property in the JSON

Resolved the verdict remark, additional tests will be added to the framework over time.
