Forbid scripting for wiki files
Wiki files (not pages - files in the repo) are just sent to the browser
with whatever content-type the mime_types gem assigns to them based on
their extension. As this is from the same domain as the GitLab
application, this is an XSS vulnerability.
Set a CSP forbidding all sources for scripting, CSS, XHR, etc. on these
files.
Fixes https://gitlab.com/gitlab-org/gitlab-ce/issues/17298.

Fix vulnerability that leaks private labels and milestones
This fixes vulnerability that leaks information about private labels and milestones because of insecure direct object reference in issueable create service.
This affects merge requests and issues.
See https://gitlab.com/gitlab-org/gitlab-ce/issues/15439
This MR introduces additional check that rejects labels and milestone that does not belong to the same project issue/merg request does.
`IssuableBaseService` may benefit from encapsulating filters in separate class/module, which then may improve coherency in this class.
Closes https://gitlab.com/gitlab-org/gitlab-ce/issues/15439

Remove persistent XSS vulnerability in `commit_person_link` helper
Because we were incorrectly supplying the tooltip title as
`data-original-title` (which Bootstrap's Tooltip JS automatically
applies based on the `title` attribute; we should never be setting it
directly), the value was being passed through as-is.
Instead, we should be supplying the normal `title` attribute and letting
Rails escape the value, which also negates the need for us to call
`sanitize` on it.
Closes https://gitlab.com/gitlab-org/gitlab-ce/issues/15126

Fix 2FA authentication spoofing
This is security fix for vulnerability described at
https://gitlab.com/gitlab-org/gitlab-ce/issues/14900.
Attacker was able to bypass password authentication of users that have 2FA enabled, and consequently sign is as a different user, without knowing his password, if he managed to guess 2FA One Time Password for that user.
It was also possible to enumerate users and check if they have 2FA enabled, because GitLab responded with different error for each case.
This MR attempts to change default user search scope if `otp_user_id` session variable has been set. If it is present, it means that user has 2FA enabled, and has already been verified with login and password. In this case we should look for user with `otp_user_id` first, before picking it up by `login`.
Both, 2FA authentication spoofing and 2FA discovery have been covered by specs.
Current 2FA code is a bit tricky, so it probably needs some refactoring.

Fix "Show all" link behavior
The "Show all" link was broken by recent refactors from @joshfng. I have fixed it very simply (I believe).
**Please note that this fix will be in 8.5.x only** (since the whole "Show all" stuff was moved to pagination recently (8.6).
Fixes#14168

Only show group member roles if explicitly requested
This very simply fixes an EE problem, but I made the change here so it's less prone to errors from merges.
In EE, prior to this change, group member roles were shown in project member list when a project is shared with a group. This is bad because the project explicitly shares with the group and sets a 'max access' level. If the max access level is 'developer' the project owner doesn't want to see 'Owner' in the group roles because it will confuse them. I verified that permissions are really being honored here, it was just an error in the view. You can see in https://gitlab.com/gitlab-org/gitlab-ee/blob/master/app/views/projects/project_members/_shared_group_members.html.haml#L18 where this was how it was intended to be. Likely a CE-EE merge introduced this bug. That's why I made the boolean required in CE even though this is for EE.
