[DRM][ClearKey] Add license url by DRM config, CK as DRM replacement

[CastagnaIT]

Description

1. Add support to set license server url from property, example:
   #KODIPROP:inputstream.adaptive.drm_legacy=org.w3.clearkey|https://server/AcquireLicense

2. Add support to pass http headers to license server request

3. Tested DASH Widevine stream, used with ClearKey as DRM replacement, as requested on Support for clearkey #811 and [Feature request] Add support for fetching keys from Licence Server #1637.
   The only limitation is that the manifest must provide the ContentProtection with urn:mpeg:dash:mp4protection:2011 containing the default_KID

4. Add support "ClearKey as DRM replacement" for HLS, but not tested since i havent found any stream

5. Add code to prevent a mixed misuse of DRM properties

6. Some code cleanups

Motivation and context

closes #1637
closes #811

How has this been tested?

Tested MPD widevine protected by using ClearKey license server url provided by DRM config property, the tested MPD does not provide the ClearKey ContentProtection tag, as follow:

        <ContentProtection schemeIdUri="urn:mpeg:dash:mp4protection:2011" value="cenc" cenc:default_KID="**7B7D**-565C-4**3-B**F-**C33**654**" xmlns:cenc="urn:mpeg:cenc:2013"/>
        <ContentProtection schemeIdUri="urn:uuid:edef8ba9-79d6-4ace-a3c8-27dcd51d21ed">
          <cenc:pssh xmlns:cenc="urn:mpeg:cenc:2013">redacted</cenc:pssh>
        </ContentProtection>
        <ContentProtection schemeIdUri="urn:uuid:9a04f079-9840-4286-ab92-e65be0885f95" value="MSPR 2.0">
          <cenc:pssh xmlns:cenc="urn:mpeg:cenc:2013">redacted</cenc:pssh>
        </ContentProtection>

i cant publish here the test stream used

3. Tested DASH Widevine stream, used with ClearKey as DRM replacement, as requested on Support for clearkey #811 and [Feature request] Add support for fetching keys from Licence Server #1637.
   The only limitation is that the manifest must provide the ContentProtection with urn:mpeg:dash:mp4protection:2011 containing the default_KID

What about extracting the default_KID from the urn:uuid:edef8ba9-79d6-4ace-a3c8-27dcd51d21ed PSSH if the default_KID doesn't exist?

iirc dash specs say default_KID should be placed on urn:mpeg:dash:mp4protection:2011 scheme, if not exists it must be extracted from the mp4box, so services that place default_KID e.g. on urn:uuid:edef8ba9-79d6-4ace-a3c8-27dcd51d21ed scheme, are not conform to dash standards

an improvement would be when not found extract it from the mp4box, but this is a change that i want left after the DRM config rework

to do what you propose currently its needed add a workaround that in theory can be avoided after the rework
so is the reason why i havent add it on the code changes, but i will try take a look

@moszkowski97 your problems are because you are using wrong ISA properties and wrong url pipe "|" along the URL is not supported on ISA and not specified on Wiki, i suggest you for full read the Wiki integration page and recheck what you are doing,
if after this you still have problems, open a new Issue thread and dont report to the development PR's

[CastagnaIT]

@alannl thanks i have saved it, your comment deleted as requested, to avoid keep comment history
i will take a look on next days

@CastagnaIT FYI, via actibity API all "deleted" comments (even from "deleted" accounts!) are visible just fine :)

@CastagnaIT
Were you able to get the video link to play? It does work with IS, Widevine and proxy.
Clearkey with altered manifest tru proxy so that KID is detected, gives this error, if this check is ignored, maybe it will work with clearkey:
ClearKeyDecrypter::CreateSingleSampleDecrypter: Cannot initialize ClearKey DRM. Only "cenc" encryption supported.
Hope it's ok to address it in this thread

[CastagnaIT]

Hope it's ok to address it in this thread

no, dont use development PR's for discussions
i verified your video but is done with cbcs encryption, and so cannot be played
this encryption is not supported atm, maybe in future
