No longer shows New Snippet button to users who aren't able to create a new snippet in the given context.
Also removes the plus icon from the New Snippet buttons, as they're no longer used in other creation buttons.
Fixes#14595.
Add min attribute to projects_limit field on user's form
This PR adds `min=0` attribute to `:projects_limit` field on user's form in the admin panel. It improves UX disallowing user to enter negative values in this field.

Avoid calculation of closes_issues.
## What does this MR do?
Avoid unneeded calls to MR closes issues
## Are there points in the code the reviewer needs to double check?
I'm not sure if calling this method from a view is a good practice, but I cannot see another simple way of avoiding this problem. In case we want to avoid this in the controller we need to specify the action, format and status of the merge request, because in that case we know that the `_open` partial will render. We could add some lazy evaluation but it not a thing I see in use along the app but feedback is welcome

Added setting to set new users by default as external
## What does this MR do?
This implements the feature request #14508. It adds an option in the application settings to set new users by default as external.
## Are there points in the code the reviewer needs to double check?
Everything. Like I mentioned in the discussion of the issue my knowledge of Ruby basically doesn't exists. I tested it on my machine and it seems to work, but as I am very unexperienced in Ruby I highly recommend to take a close look at the code.
## Why was this MR needed?
It was requested by @DouweM to work on the issue with the proposed changes by me.
## What are the relevant issue numbers?
This MR is for the issue #14508 that followed up after the implementation of #4009.

Allow specifying protected branches using wildcards
Closes#18627
# Tasks
- [ ] #18627!4665 Allow specifying protected branches using wildcards
- [x] Find existing usages of protected branches
- Protecting branches
- `ProtectedBranchesController` is used to mark a branch protected/unprotected
- `API::Branches` can be used to mark a branch protected/unprotected
- Enforcing branch protection
- `Gitlab::GitAccess` has helpers (`can_push_to_branch?`, `check`) that are used to deny pushes if a branch is protected
- Over SSH: `gitlab-shell` receives a push, and calls `/allowed` on the GitLab API, which calls `GitAccess.check`
- Over HTTP:
- `gitlab-workhorse` receives the request, and forwards it to rails
- Rails (in the `GitHttpController#git-recieve-pack`) runs basic checks (is the user logged in, not protected branch checks) and returns ok with `GL_ID` and `RepoPath`
- `gitlab-workhorse` looks at the response, and calls the relevant `gitlab-shell` action from `git-http/handlePostRPC`
- Rest of this flow is the same as the SSH flow above

Exclude projects pending delete from notifications
Make `NotificationSetting.for_projects` exclude projects that are excluded by the default scope on `Project`. (At the moment, that's projects with `pending_delete: true`.)
See https://gitlab.com/gitlab-com/support-forum/issues/819
See merge request !5138
If the Sidekiq job fails for some reason, a project can be 'stuck'
pending deletion. The project can't be viewed, so it shouldn't be
available through the notification settings association as this will
throw an exception when we try to show the link.
Escape file extension when parsing search results
When a file extension contains characters which have a meaning in regular expressions, the search may crash.
Fixes#18553
See merge request !5141
As requested by the issue #14508 this adds an option in the application
settings to set newly registered users by default as external. The
default setting is set to false to stay backward compatible.
Show last push widget in upstream after push to fork
## What does this MR do?
Show the last push widget in the upstream project when you push to a fork.
## Are there points in the code the reviewer needs to double check?
In the view, I'm checking if `@project` in the first part of the conditional. I felt it was necessary in case `@project` wasn't an object in all cases. Will it ever not be there? Is this check necessary?
Should there be tests? I don't see existing ones for this.
## Why was this MR needed?
I use the fork workflow everywhere and it has annoyed me for some time that the last push widget doesn't show up when viewing the upstream project. I'm almost never viewing the fork in GitLab so I want to be able to easily create a MR in any case.
## Screenshots (if relevant)
**Widget in upstream repo:**

**Widget in fork**:

**Widget on dashboard**:

Allow everyone to order tags, not only those who has access
## What does this MR do?
Allows everyone to view tags by different order (by name, date, etc), not only those who has access
## Are there points in the code the reviewer needs to double check?
Just check how it's rendered.
## Why was this MR needed?
Because now I can't order other's project tags.

Fix diff comments not showing up in activity feed
## What does this MR do?
It fixes the detection of note events to check for `Note` and `LegacyDiffNote`.
## Are there points in the code the reviewer needs to double check?
No? /cc @DouweM (since I believe you introduced `LegacyDiffNote`
## Why was this MR needed?

Fixing URL validation for import_url on projects
Fixes https://gitlab.com/gitlab-org/gitlab-ce/issues/17536
This MR fixes problems related to bypassing `import_url` validation on projects. This makes sure the URL is properly validated so we don't enter crap and fail while running workers that handle this URL.
It also adds a migration to fix current invalid `import_url`s
See merge request !4753
Add lib/gitlab/emoji.rb instead of gitlab_emoji gem and upgrade Gemojione
- No reason to split it into a separate gem when the gem barely did anything. We can use gemojione directly, making updating gemojione that much easier. Unless there's a particularly good reason we were using the gem?
- Fixes the Rake task since it broke after all the AwardEmoji changes.
- Update gemojione to 2.6.1.
Spring Update changes! http://emojione.com/releases/#2.2.0
