Revert "Merge branch 'wiki-fix' into 'master'"

This reverts commit 4cc85a58 (!4026), reversing
changes made to 90ae445b.

From https://gitlab.com/gitlab-org/gitlab-ce/merge_requests/4026#note_11719950:

>  1. On Ruby 2.1.x, the [`uri.path = ::File.join(project_wiki_base_path, uri.path)`](https://gitlab.com/gitlab-org/gitlab-ce/blob/master/lib/banzai/filter/wiki_link_filter.rb#L39) raises an `URI::InvalidComponentError: bad component(expected relative path component): http://bar.com/baz` error in `Banzai::Filter::WikiLinkFilter#rebuild_wiki_uri`, which is then rescued in [`Banzai::Filter::WikiLinkFilter#process_link_attr`](https://gitlab.com/gitlab-org/gitlab-ce/blob/master/lib/banzai/filter/wiki_link_filter.rb#L34), thus the link is not modified and the tests pass.
1. On Ruby 2.2.x, the same line doesn't raise an error anymore, thus tests are broken on Ruby 2.2 only. I didn't really understand yet why having absolute links in the wiki would break some tests vs having relative links as before, but I think the safest course to action is to revert this MR and to find another fix (probably just prepending `ProjectWiki#wiki_base_path` with the relative URL path component if we are in the case of a relative URL...

Remove the annotate gem and delete old annotations

In 8278b763 the default behaviour of annotation
has changes, which was causing a lot of noise in diffs. We decided in #17382
that it is better to get rid of the whole annotate gem, and instead let people
look at schema.rb for the columns in a table.

Fixes: #17382

Don't read otp_secret_encryption_key from hardcoded path in models/user

Variable `Gitlab::Application.config.secret_key_base` is set in config/initializers/secret_token.rb. It's very bad practice to use hard-coded paths inside an application and really unnecessary in this case.

[same-level](same-level) -> <a href="same-level">same-level</a>
[sub-level](sub/level) -> <a href="sub/level">sub-level</a>
[upper-level](../upper-level) -> <a href="../upper-level">upper-level</a>

Pass trusted_proxies to action_dispatch as IPAddrs instead of strings

Fixes an issue introduce in: https://gitlab.com/gitlab-org/gitlab-ce/merge_requests/3524

Fixes: https://gitlab.com/gitlab-org/gitlab-ce/issues/17004

See merge request !3970

If you attempt to push thousands of branches at once, the 60-second timeout
will occur because GitAccess checking does a lot of work to check if the
user has permission to push to a branch. This changes does two things:

1. Instead of making 1 DB query per branch push, use a memoized list of protected branches to check
2. Memoize what permissions the user has to perform on this project

On a test of 10,000 branch pushes, this prevents gitlab-shell from hitting the 60-second
timeout.
