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

## What does this MR do?

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?


## Why was this MR needed?
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`.

Make deleting with optimistic locking respect NULL

Make deleting with optimistic locking respect NULL

For now deleting with optimistic locking is broken when
lock_version is still NULL, because Rails would try to
delete with `lock_version = 0` while in the database
the column is still `NULL`.

The monkey patches would force Rails just pass whatever
in the column, and stop Rails from casting `NULL` into `0`
when the value is read from database.
