Use Project#full_name instead of name_with_namespace

See merge request gitlab-org/gitlab-ce!17601

We only allow users that can merge the merge request to push to the
fork.

When creating a cross project merge request without changes. The MR
widget shows the option to create a new file. It would however link to
the wrong project.

Using the relation `Project#source_of_merge_requests` in
`Ci::CreatePipelineService`

That way we take advantage of all the `ActiveRecord::Relation` magic

The query becomes a lot simpler if we can check the branch name as
well instead of having to load all branch names.

Backport of "Geo: Ignore remote stored objects when calculating counts"

See merge request gitlab-org/gitlab-ce!17581

When an MR is created using `allow_maintainer_to_push`, we enable some
abilities while the MR is open.

This should allow every user with developer abilities on the target
project, to push to the source project.

When a project is not private, and the source branch not protected the
user can now select the option to allow maintainers to push to this
branch

This flag will allow maintainers of a project to push to specific
branches of a fork of a project
