Set a `sha` parameter on the MR form. If this doesn't match the HEAD of
the source branch when the form is submitted, show a warning (like with
a merge conflict) and don't merge the branch.
Merge Builds and Pipelines tab into one
Based on https://gitlab.com/gitlab-org/gitlab-ce/merge_requests/4053#note_12064642. Main idea is to keep all CI-related pages under one tab. So we can keep top navigation clean.
First I tried `CI/CD` naming but it looked weird so I just used Pipelines as tab name. I did not change project settings naming.

Separate reference gathering from rendering
This is a required step to allow batch processing when gathering references. This in turn would allow grabbing (for example) all mentioned users of an issue/merge request using a single query.

Fix cancelability and retriablity of pipeline with generic statuses
Currently it's not possible to cancel or retry generic status since this is external thing to GitLab.
This fixes shown actions of pipelines containing only these actions.
See merge request !4380
Fixed potential issue with 2 ci status polling events happening
Possible cause for double notifications was if the request was slow & then you changed page whilst this request was happening it would finish on another page & then launch another interval - this stops that issue.
Also passed in the CI status as an option value rather than waiting for the first ajax request to finish

Reduced number of buttons in commit header

Reduces the buttons in the commit header.
## What are the relevant issue numbers?
Closes#17576

Replace `link_to_gfm` with `link_to` in merge request and issue titles.
## What does this MR do?
This removed GitLab Markdown Formatting from issue titles due to issues and confusion it caused as well as performance reasons.
On the issue/MR page itself, the formatting is preserved. This only effects index pages. See:

I think the trade-off here is worth it, otherwise we'd just be playing wack-a-mole.
## Are there points in the code the reviewer needs to double check?
I don't think so.
## Why was this MR needed?
Previously if an issue had an emoji for its name it would be unclickable. Similarly, links were rendered inline if the title was something like “Fixes a bug with https://google.com”. This confused a number of users, so it’s removed.
This is also ever so slightly more performant :)
## What are the relevant issue numbers?
This fixes#17614 and #17230.

Fix grammar and wording in text on various pages.

Fixes various grammatical and/or wording issues I found while copyediting on the plane :)

Incorrect grammar and weird/confusing wording makes the product look less polished and professional.
