workaround for forks with an invalid repo
Fixes https://gitlab.com/gitlab-org/gitlab-ce/issues/13465
The error occurs when a project returns a `nil` commit for a variety of reasons, I assume the repository is corrupt - perhaps as a result of a failed fork.
With this MR, we do not show forks with corrupted repos in the list of forks, as this does not seem to work anyway. A better solution is to fix the cause of the issue and/or any data integrity problem...
Also fixing Sentry issue: 1180
`undefined method 'already_forked?' for nil:NilClass `
See merge request !2836
Use SCAN during 'rake cache:clear'
This allows 'rake cache:clear' to delete millions of keys without
choking. It requires Redis 2.8.0 or newer but we needed that already
anyway.

Only set autocrlf when creating/updating files

Uses cross browser niceScroll to do scrolling on sidebar.
Fixes: #13544
Firefox does not support `-webkit-scrollbar` and there is no alternative for FF. So for example Gmail falls back to no fancy scrollbar. Stuck with jQuery, which is a good solution, since we already use it.
This also leaves the default scrollbar as is.

Also fixes horz scroll issue:

Reduce code complexity on GitPushService#execute
Code complexity for gitlab-ce after this has been refactored:
```
27.3: GitPushService#execute
```
This still needs to be merged into `gitlab-ee` presumably with conflicts... Perhaps we should create another issue for doing that?
I left the code sort of similar to what it was... If I could, I would have refactored most of the code into separate classes, etc. as it breaks probably all SOLID principles.

Fix CI builds scheduler when first build in stage is allowed to fail
This fixes an edge case in CI builds scheduler when first build in stage was marked as allowed to fail.
Closes#3192
See merge request !2869
Re-add section about NGINX config and init script updates in 8.4->8.5 update doc
These sections were removed by !2766 but:
- even if the NGINX config wasn't modified, it might
be in future updates so it's better to always have
it instead of having to remember to add it depending
on the changes
- the init script update section must be there since
it's a safe command line that should be run on every update
This fixes https://github.com/gitlabhq/gitlabhq/issues/10031.

Prevents floated button group on issues view
Issue #13359

See merge request !2826
This ensures that _all_ caches (including any caches normally only
flushed under certain conditions) are flushed whenever a project is
removed. Because cache keys are based on project namespaces (excluding
IDs) not doing so could result in a newly created project re-using old
caches (if the project was re-created using the same name).
This ensures the caches for Repository#empty? and
Repository#has_visible_content? are flushed after a repository has been
imported or forked.

fix table in doc/ci/variables/README.md
The table was missing a column separator, causing GitLab to render the
markdown incorrectly.
