This module is now the sole source of knowledge for *how* we render
Markdown (and GFM).

Properly daemonize the mail_room process

The old invocation only worked by accident because we have a '&'
somewhere in the init script for expediency. When ran from a terminal,
the mail_room daemon process ended up in the session of the terminal.
This commit adds a small wrapper that tries to do the textbook
daemonization steps (double fork, setsid etc.) while also taking
care that the pidfile is written before the 'start' process exits.

See merge request !1221

Apply syntax highlighting to fenced code blocks client-side

Instead of applying the syntax highlighting scheme class to these blocks
server-side, we use Javascript and Gon to apply the user's color scheme
(or the default) client-side.

This will make it easier to cache these blocks in the future because
they're no longer state-dependent.

Prevents an unstyled flash that occurs when we were only applying the
syntax highlighting class in Javascript. Now for these uncached blobs
the server can add the syntax class, and for (possibly) cached fenced
code blocks, the Javascript will add it as needed.

Prevent too many redirects error when home page URL set to external_urll

Many users naively set the home page URL setting to external_url
(e.g. https://mydomain.com). When an unauthenticated user signs in, this
causes endless redirections. For example, this is occuring:

1. Unauthenticated user attempts to access https://mydomain.com/dashboard
2. Application redirects to the home page URL: https://mydomain.com
3. Repeat step 2

In step 3, ApplicationController should have redirected the user to
https://mydomain.com/users/sign_in. Disabling the redirection if home
page URL is the same as external_url prevents users from messing up.

* Closes https://github.com/gitlabhq/gitlabhq/issues/8843
* Closes #2057

Change plots to bar graphs

Since line plot does not make sense for this kind of plots, change them to bar graphs. Bar graphs are easier to read and they look cool too.

I would like to change commits per author plots to bar graphs too, but code looks too messy to modify.
