Introduces suggestion grouping on the search box and adds the ability to the user to remove the location to search on.


**Notes**
- Suggestions are now grouped by category.
- Suggestions are displayed when no location is set.
  - Would be great to provide suggestions for the specified location which could be a project or group.
- A location is set from the server for projects/groups related urls.

Make entire todo row clickable

Fixes #14547 

I had some issues with timeouts when searching for the selector to click on, so I ended up using `execute_script`. Please let me know if you think there's a better solution

Pre-calculate Emoji digests

cc @dzaporozhets @rspeicher 

@marin Do you happen to know if we allow users to configure asset hosts anywhere in Omnibus and such? I've not been able to find any reference to "asset_host" so it seems we don't allow this (which is a good thing as this simplifies the code).

See merge request !3458

By pre-calculating the digests we can manually construct the emoji URLs,
removing the need for using Rails' asset URL helpers. The reason we
don't want to use these helpers for Emojis is two-fold:

1. Rails' image_url() method is slow, really slow. For one it _might_
   have to calculate digests but it also performs a lot of other
   intensive operations (judging by the source code and based on
   measuring timings).

2. We have a lot of Emoji which coupled with the above can result in it
   taking minutes to load Emoji autocomplete data.

Using this pre-calculation setup generating the digests takes around 7
seconds (including the time it takes to start Rails/Rake), and only
around 600 milliseconds to load _all_ the autocomplete data of a project
(measured locally).

This commit _does_ change the Emoji URLs from absolute to relative URLs
as these are much easier to generate.

To update the Emoji data simply run:

    rake gemojione:digests

Then commit any changes.

Fixes gitlab-org/gitlab-ce#14009

Isolate CarrierWave uploads in test enviroment

Purpose of this merge request is to isolate CarrierWave uploads in test environment, from regular development/production uploads.
We need to persist some files in order to test some features thoroughly. If we - for example - want to check if file exists after being uploaded via API, or we need to write tests that check if file has been correctly removed we need to persist uploads using CarrierWave.

This approach simply sets `root` path for uploads in test environment and removes temporary directory after executing RSpec tests suite. We set this in `spec_helper` to keep this in one place, this also can be set up in test environment initializer.

This issue is a workaround for #12968, but does not solve this problem completely, because if uploader defines absolute path in `store_dir` or defines custom `root` path, this may not work correctly (but it looks like we do have such uploaders at this moment).

Fix Raw / Rendered diff producing different results on merge requests

The raw diff endpoint (`merge_requests/####.diff`) produces a diff based on `target_branch` instead of the original branching point. Same is valid for `merge_requests/####.patch`.

Fixes #14680, #3017
