See merge request !6306

Fix two problematic bits of code that will be deprecated or broken in Rails 5.

Found in the Rails 5 MR: !5555

These are safe to use in Rails 4.2.7 as well as Rails 5.0.0, so I figured I'd backport them for the sake of making that merge request smaller.

The explanation for the mime_types.rb code is here: https://github.com/rails-api/active_model_serializers/issues/1027#issuecomment-126543577

See merge request !6214

Update templates.

Only add original author tag line when importing from GitHub if there isn't a linked GitLab account

## What does this MR do?
If there we've found a linked GitLab user for a creator of an issue or comment don't add the 'Created By:' line.

## What are the relevant issue numbers?

Closes #21569

Make the cases clear instead of having guards

See merge request !6304

Fixes gitlab-org/gitlab-ce#22070

[ci skip]

Only check :can_resolve permission if the note is resolvable

See merge request !6298

MySQL could not have support for millisecond precision, depends on the MySQL version 
so we just create issues in different seconds in a deterministic way

Currently this permission check incurs a significant performance hit on loading issues
where it does not make sense to check this permission in the first place.

API: Use Search::GlobalService in projects search API

See merge request !6280

Fix API issues sorting

## What does this MR do?

Fix the sorting of issues in the API.

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

Instead of removing the '_at' suffix manually, we could add those versions to the `Sortable` concern instead.

## Why was this MR needed?

There were a couple of bugs:

* The global and project-specific issues endpoints wouldn't sort at all.
* Group sorting would work, but only if you applied two undocumented workarounds:
  * Always pass both `order_by` and `sort` (both are optional, so only one should be needed to change ordering).
  * Instead of passing `created_at` or `updated_at`, you needed to pass `created` or `updated`.

This makes the API implementation match the docs.

See merge request !6281

Also streamline the sorting part while we're at it.

That being done, there's currently a duplication between
`GET /projects/search/:query` and `GET /projects?search=:search`
so we might want to keep only the latter for 9.0...

Add notification_settings API calls

## What does this MR do?
It adds API calls to get/update notification settings, globally and at the group/project level.

## Are there points in the code the reviewer needs to double check?
None

## Why was this MR needed?
Notification settings were updated, but related API calls were never created.

Pull import sources from Gitlab::ImportSources

## What does this MR do?
`ApplicationSettings.create_from_defaults` defines an array of import sources, but we should be pulling them from `Gitlab::ImportSources.options` since that's what they're validated against.

## What are the relevant issue numbers?

Closes #21814

See merge request !6293

refactors update file

Restrict ldap return attributes

## What does this MR do?

Fixes the CE part of #13821. We really only ever need uid, dn, cn, and mail attributes, and in some cases, even less. This merge request strips the request down to those four attributes by default, and allows the caller to specify others, if needed. 

## Why was this MR needed?

This will improve performance especially in cases where the connection is slow between GitLab and LDAP, or when the LDAP object has lots of attributes we don't care about.

See merge request !6187

Pass the remember_me option into the u2f form and support it while authenticating

## What does this MR do?

Adds remember me support in the u2f authentication, and makes sure the flag gets passed from the login form to the u2f form.

Based on the changes for the same thing done for regular 2fa: https://gitlab.com/gitlab-org/gitlab-ce/merge_requests/4369

## Why was this MR needed?

The remember me option wasn't working for u2f devices (yubikey)

## What are the relevant issue numbers?

Fixes https://gitlab.com/gitlab-org/gitlab-ce/issues/18103
