Gitea runs diff on highlighted code fragment for each line in order to
provide code highlight diffs. Unfortunately this diff algorithm is not
aware that span tags and entities are atomic and cannot be split.
The current fixup code makes some attempt to fix these broken tags
however, it cannot handle situations where a tag is split over multiple
blocks.
This PR provides a more algorithmic fixup mechanism whereby spans and
entities are completely coalesced into their respective blocks.
This may result in a incompletely reduced diff but - it will definitely
prevent the broken entities and spans that are currently possible.
As a result of this fixup several inconsistencies were discovered in our
testcases and these were also fixed.

The gitea cmd/serv.go setup function deletes the console logger to
prevent stdout interference with commands. However, the problem is that
it then calls setting.NewContext which may cause an exit with log.Fatal
- which will then not be shown.
Now, log.Fatal is so disastrous that the interference that logging
causes is wanted. However, we can avoid stdout interference by emitting
on stderr.
This PR forces the creation of a console logger on stderr listening on
Fatal for these commands. Most commands have a `--debug` option now that
will print more reasons too - however, defaulting to give the log for
Fatal seems reasonable.

* Add configurable Trust Models
Gitea's default signature verification model differs from GitHub. GitHub
uses signatures to verify that the committer is who they say they are -
meaning that when GitHub makes a signed commit it must be the committer.
The GitHub model prevents re-publishing of commits after revocation of a
key and prevents re-signing of other people's commits to create a
completely trusted repository signed by one key or a set of trusted
keys.
The default behaviour of Gitea in contrast is to always display the
avatar and information related to a signature. This allows signatures to
be decoupled from the committer. That being said, allowing arbitary
users to present other peoples commits as theirs is not necessarily
desired therefore we have a trust model whereby signatures from
collaborators are marked trusted, signatures matching the commit line
are marked untrusted and signatures that match a user in the db but not
the committer line are marked unmatched.
The problem with this model is that this conflicts with Github therefore
we need to provide an option to allow users to choose the Github model
should they wish to.
