rDLDBASEc87c8c79ea66: debian: Remove the extrinsic version from release names
Summary

Use only the intrinsic version (eg. 1.0.0) instead of the extrinsic version
(eg. stretch/contrib/1.0.0).
Releases should only contain data from DSC, not external 'pointers' to them.

Additionally, having extrinsic data in releases means the same
dsc-sha256 extid can point to different releases, which meant the loader
may reuse a release mentioning a specific suite as a release in a
different suite.
With this commit, this won't be a problem anymore, as releases won't
mention the suite at all, so suites can safely share extids.

Depends on D6748

Note: this diff fixes data corruption, that at best crashes the loaders,
at worst makes them write wrong stuff. In order to fix it, we need to wipe
all ExtIDs from the database with type dsc-sha256 pointing to a release SWHID.

    debian: Fix confusion between the two versions
    
    'version' was documented as the intrinsic version (eg. '0.7.2-3') and
    'full_version' as the one containing the suite name (eg. 'stretch/contrib/0.7.2-3').
    
    In practice, it was the opposite, except in a few incorrect test.
    
    This commit fixes said tests, and renamed 'full_version' to
    'intrinsic_version'.
    
    This is only a refactoring, the behavior is unchanged for now;
    but a future commit will remove the 'version' (which is extrinsic) from
    the release name (which should contain only data intrinsic to the DSC).

Looks good to me.

Indeed, releases with the same intrinsic version target the same directory regardless of the suite (see example below before that diff) so nice catch !

Thanks for fixing this.

I'm not too sure about wiping the extids. Sounds like a case for bumping the expected extid_version instead.

Bumping the extid_version means we need to reload Debian entirely from scratch. By just wiping these release extids, we'll only discard what was loaded in the last couple of weeks.

Yes.

That is much, much more annoying to do.
