Instead of doing a full refresh of the page - i've modified the filterResults method on the Issues object to work for this form as well

Add space to separate different files in diff

I propose to add some visual separation between files in diff. Originally this separation was removed in 8.0 because of different UI layout. Now when we have white layout back I think it will be better to add some space between files.

Removed diverging commit count calculation from Repository#build_cache

Using a repository with 1000 branches the old `Repository#build_cache` method would take around 180 seconds to complete. Without calculating the diverging commit counts this method "only" takes around 60 seconds. 

See commit 28cc2413eb5ddf920ce0b5eed803121f8b884754 for more details. This fixes https://gitlab.com/gitlab-org/gitlab-ce/issues/14058

Use relative links in `doc`, fix broken generated HTML links

Links like (doc/web_hooks/web_hooks.md) work in the GitLab source code
web interface, but the HTML generator produces broken links in the `doc`
subdirectories:  
http://doc.gitlab.com/ce/hooks/doc/web_hooks/web_hooks.html  
instead of the right one  
http://doc.gitlab.com/ce/web_hooks/web_hooks.html  
in  
http://doc.gitlab.com/ce/hooks/custom_hooks.html.

Bump Git version requirement to 2.7.4

[ci skip]

See merge request !3281

When calling Repository#build_cache we _don't_ want to build the
diverging commit count cache as doing so can be _very_ slow for
repositories with lots of branches. Because these caches are built
whenever needed (= when actually viewing the list of branches in the web
UI) we can safely remove this code from
Repository#build_cache.

This method is not used or tested anywhere.

Cache project avatars stored in Git

Related issue: https://gitlab.com/gitlab-org/gitlab-ce/issues/14363

See merge request !3272

The avatar logic has been moved from Project to Repository as this makes
caching easier. The logic itself in turn has been changed so that the
logo file names are cached in Redis. This cache is flushed upon pushing
a commit but _only_ if:

1. The commit was pushed to the default branch
2. The commit actually changes any of the logo files

If no branch or commit is given the cache is flushed anyway, this
ensures that calling Repository#expire_cache without any arguments still
flushes the avatar cache (e.g. this is used when removing a project).

Fixes gitlab-org/gitlab-ce#14363

no

## Why was this MR needed?
Unexpected behavior as a user
