Git repos are then associated with a context, (usually the request's context) - with sub commands using this context as their base context.

* 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.

If you attempt to merge to a branch which on a PR there will be a nil pointer error in the pull request checker.
This panic is uncaught and will bring down the gitea server.
This PR adds protection to prevent this.
The commit status code has a bug whereby setting the initial status to Pending means you can never have the status of Success - it should be set to Success.
* Only check for merging if the PR has not been merged in the interim
* fixup! Only check for merging if the PR has not been merged in the interim
* Try to fix test failure

* return already merged error
* enforce locking
