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
## Summary
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
## Fix
This MR introduces additional check that rejects labels and milestone that does not belong to the same project issue/merg request does.
## Further work
`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.

Check permissions when sharing project with group
## Summary
Unprivileged user was able to share project with group he didn't have access to, and therefore gain partial access to that group, which opened possibilities for further actions like listing private projects in that group.
See https://gitlab.com/gitlab-org/gitlab-ce/issues/15330
## Fix
This change introduces additional check for group read access.
## Further work
We can think about preventing such problems in the future (this is quite common problem) by moving permissions checks to another layer of abstraction (TBD).

Fix revoking of authorized OAuth applications
Users were not able to revoke access to authorized OAuth applications. Clicking the "Revoke" button would result in a 404 page, and the application would still be authorized.
Added a spec and also found that the `gon` variables were not being set for this view.

Fix#14753: Check if head is born before trying to detect main language
This MR makes sure that head exists before trying to detect the main language.
This prevents errors on repo's without a master branch.
Closes#14753

Unblocks user when active_directory is disabled and it can be found
We implemented a specific block state to handle user blocking that originates from LDAP filtering rules / directory state in !2242.
That introduced a regression in LDAP authentication when Active Directory support was disabled. You could have a scenario where the user would not be temporarily found (like a filtering rule), that would mark the user as `ldap_blocked`, but will never unblock it automatically when that state changed.
Fixes#14253, #13179, #13259, #13959

Fix 2FA authentication spoofing
## Summary
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.
## Fix
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.
## Further work
Current 2FA code is a bit tricky, so it probably needs some refactoring.

Related to gitlab-org/gitlab-ce#14937 (but does not fully fix) This is a temporary fix so performance isn't affected so much.
