Prevent remote mirrors from failing when project is in pending_delete

We noticed on GitLab.com that remote mirrors were not even running.
UpdateAllRemoteMirrorsWorker was failing on a project that was in

The models were incorrectly merged (this would have been avoided if !927

Instead of doing n queries for n states, do one query to get all the
counts grouped by state, and figure out what the count is for each state
is from that. We can still cache the individual counts (it can't hurt),
but this will help with initial load.

Note that the `opened` scope on `Issuable` includes the `opened` and
`reopened` states, which is why there's a special case.

`any?` on an AR relation performs a `SELECT COUNT`, which we don't need.

1. We are very likely to have issues or MRs, so the `SELECT COUNT` is
   often unnecessary.
2. Even where there are no items returned, the overhead of the
   `SELECT *` instead of `SELECT COUNT` is relatively small.

Calling `to_a` on the relation lets us use `Enumerable#any?`, which will
return immediately if there are objects returned.

Don't allow to specify a repo or version when installing Workhorse

I've also updated the "patch version upgrade" doc since I did forget to update it in !6574.

Pass commit data to ProcessCommitWorker

This changes `ProcessCommitWorker` so that it takes a Hash containing commit data instead of a commit SHA. This means the worker doesn't have to access Git just to process a commit message (and other data it may use). This in turn should solve the problem of ending up with 15 000-something jobs in the `process_commit` queue that take forever to process.

Allow public access to some Project API endpoints

## What does this MR do?

This opens up a few endpoints in the Project API:

- `GET /projects/visible` (returns public projects only)
- `GET /projects/search/:query` (returns results only for public projects)
- `GET /projects/:id` (only if the project is public)
- `GET /projects/:id/events` (only if the project is public)
- `GET /projects/:id/users` (only if the project is public)

## Are there points in the code the reviewer needs to double check?

I've chosen to explicitly add `authenticate!` to GET methods that still need a current user.

Pipelines tabs

## What does this MR do?
Changes the URL when the builds tab is clicked making it possible to be shared.

1. Adds a standard way to handle linked tabs:
    *   This behaviour is already present in the merge requests, commit and user `show` page. 
    *    This MR introduces a reusable way to accomplish this behaviour for pages with static content.

2. Adds test:
    *   For the linked tabs reusable class
    *  For the pipelines tabs

## Why was this MR needed?
To allow having a sharable URL that represented the opened tab

Resolve "User-generated permalink IDs collide with GitLab interface"

## What does this MR do?

Prevents ID values automatically generated by headers in [GitLab Flavored Markdown](https://github.com/gitlabhq/gitlabhq/blob/master/doc/user/markdown.md#header-ids-and-links) from colliding with IDs used elsewhere in the GitLab interface.  This can cause confusion when, for instance, a selector looks for a merge request tab with `id="pipelines"` and there is a header with the same ID earlier in the DOM.

How this works:
* All header IDs generated with GitLab Flavored Markdown are namespaced with `id="user-content_foo"`
* All anchor links which point to these IDs continue to use the non-namespaced hash `<a href="#foo">...</a>`
* When a page is loaded or when the `hashchange` event is triggered, javascript will automatically search for `#user-content_foo` if `#foo` cannot be found, and scroll to that position instead.

Remove the help text under the sidebar subscribe button and style it inline

## Are there points in the code the reviewer needs to double check?

Current help text is over obvious and pushes references too far down. Also the subscribe button is now consistently styled and not a complete block button anymore. approved by @awhildy

Resolve "Improper use of bootstrap media query variables"

## What does this MR do?

Corrects media queries which are off by `1px` due to incorrect `$screen-{xs,sm,md,lg}-min` usage.

## Are there points in the code the reviewer needs to double check?

Ensure none of these errors were somehow intentional (I can't imagine a legitimate use case for `@media (max-width: $screen-sm-min)` though)

## Why was this MR needed?

When "min" breakpoints are used for "max-width" media queries, they create an overlap in rule breakpoints.  For instance in the following scenario:

```scss
.foo {
  @media (min-width: $screen-sm-min) {
    width: 100px;
    padding: 0;
  }
  @media (max-width: $screen-sm-min) {
    padding: 10px 0;
  }
}
```

If the viewport were set to exactly `$screen-sm-min` pixels, both of these media queries would apply.  It is important to use `max-width: $screen-xs-max` in this case which is equal to `$screen-sm-min - 1`.
