This could be justified from a semantic point of view, and also can help
in bringing more attention to where this information is, as it is less
hidden, now.
Also add Dev Guide as one of our resources in our Readme.
It was pointed out by a contributor that our workflow mentioned
rewrite-branch as the preferred way, while in fact our policy is to add
said changes to a different commit. Updating documentation to prevent
other situations like that.
As part of the process of moving documentation from redmine
to "Read the Docs", this commit moves installing Suricata using git
page from redmine wiki into Suricata Developer Guide section.
It also updates the necessary steps.
Ticket: #5585
That page existed only in our redmine. Updated and added a few things,
like a paragraph about our expectations for feature contributors.
Also updated links, contacts and some other processes that may have
changed since last edition.
Added some section labels in related documents, for ease of referencing.
Task #4929
Moved devguide dir into userguide dir.
Since the devguide is now incorporated as the last chapter of the
userguide, removed build and configuration files from the devguide
dir, as these are no longer needed.
