docs: better docs, mv doxygen to sphinx
This patch refactors the VPP sphinx docs
in order to make it easier to consume
for external readers as well as VPP developers.
It also makes sphinx the single source
of documentation, which simplifies maintenance
and operation.
Most important updates are:
- reformat the existing documentation as rst
- split RELEASE.md and move it into separate rst files
- remove section 'events'
- remove section 'archive'
- remove section 'related projects'
- remove section 'feature by release'
- remove section 'Various links'
- make (Configuration reference, CLI docs,
developer docs) top level items in the list
- move 'Use Cases' as part of 'About VPP'
- move 'Troubleshooting' as part of 'Getting Started'
- move test framework docs into 'Developer Documentation'
- add a 'Contributing' section for gerrit,
docs and other contributer related infos
- deprecate doxygen and test-docs targets
- redirect the "make doxygen" target to "make docs"
Type: refactor

+*******************************
+Getting a Patch Reviewed
+*******************************
+
+This section describes how to get FD.io VPP sources reviewed and merged.
+
+Setup
+========
+
+If you don't have a Linux Foundation ID, `create one here. <https://identity.linuxfoundation.org/>`_
+
+With your Linux Foundation ID credentials sign into `Gerrit Code Review at gerrit.fd.io <https://gerrit.fd.io/r/login/%23%2Fq%2Fstatus%3Aopen>`_
+
+`Install git-review, <https://www.mediawiki.org/wiki/Gerrit/git-review>`_ which is a "command-line tool for Git / Gerrit to submit a change or to fetch an existing one."
+
+If you're on Ubuntu, install keychain:
+
+.. code-block:: console
+
+ $ sudo apt-get install keychain
+
+ssh keys
+-------------
+
+To get FD.io VPP documents reviewed the VPP repository should be cloned with ssh. You should be logged into Gerrit Code Review as noted above.
+
+Create your public and private ssh key with:
+
+.. code-block:: console
+
+ $ ssh-keygen -t rsa
+ $ keychain
+ $ cat ~/.ssh/id_rsa.pub
+
+Copy **all** the contents of the public key (id_rsa.pub) output by the above **cat** command. Then go to your `SSH Public keys settings page <https://gerrit.fd.io/r/#/settings/ssh-keys>`_, click **Add Key ...**, paste your public key, and finally click **Add**.
+
+.. _clone-ssh:
+
+Clone with ssh
+==============
+
+Clone the repo with:
+
+.. code-block:: console
+
+ $ git clone ssh://gerrit.fd.io:29418/vpp
+ $ cd vpp
+
+This will only work if the name of the user on your system matches your Gerrit username.
+
+Otherwise, clone with:
+
+.. code-block:: console
+
+ $ git clone ssh://<YOUR_GERRIT_USERNAME>@gerrit.fd.io:29418/vpp
+ $ cd vpp
+
+When attempting to clone the repo Git will prompt you asking if you want to add the Server Host Key to the list of known hosts. Enter **yes** and press the **Enter** key.
+
+Git Review
+===========
+
+The VPP documents use the gerrit server, and git review for submitting and fetching patches.
+
+
+New patch
+-----------------
+
+When working with a new patch, use the following commands to get your patch reviewed.
+
+Make sure you have modified the correct files by issuing the following commands:
+
+.. code-block:: console
+
+ $ git status
+ $ git diff
+
+Then add and commit the patch. You may want to add a tag to the commit comments.
+For example for a document with only patches you should add the tag **docs:**.
+
+.. code-block:: console
+
+ $ git add <filename>
+ $ git commit -s
+
+The commit comment should have something like the following comment:
+
+.. code-block:: console
+
+ docs: A brief description of the commit
+
+ Type: Improvement (The type of commit this could be: Improvement, Fix or Feature)
+
+ A detailed description of the commit could go here.
+
+Push the patch for review.
+
+.. code-block:: console
+
+ $ git review
+
+If you are creating a draft, meaning you do not want your changes reviewed yet, do the following:
+
+.. code-block:: console
+
+ $ git review -D
+
+After submitting a review, reset where the HEAD is pointing to with:
+
+.. code-block:: console
+
+ $ git reset --hard origin/master
+
+Existing patch
+-----------------------
+
+The "change number" used below is in the URL of the review.
+
+After clicking an individual review, the change number can be found in the URL at "https://gerrit.fd.io/r/#/c/<*CHANGE_NUMBER*>/"
+
+To view an existing patch:
+
+.. code-block:: console
+
+ $ git review -d <change number>
+ $ git status
+ $ git diff
+
+.. caution::
+
+ If you have made changes and do "git review -d <change number>", your current
+ changes will try to be stashed so that the working tree can change to the review branch
+ you specified. If you want to make sure you don't lose your changes, clone another Gerrit
+ repo into a new directory using the cloning steps shown in :ref:`clone-ssh`, and perform
+ "git review -d <change number>" in this new directory.
+
+To modify an existing patch, make sure you modified the correct files, and apply the patch with:
+
+.. code-block:: console
+
+ $ git review -d <change number>
+ $ git status
+ $ git diff
+
+ $ git add <filename>
+ $ git commit --amend
+ $ git review
+
+When you're done viewing or modifying a branch, get back to the master branch by entering:
+
+.. code-block:: console
+
+ $ git reset --hard origin/master
+ $ git checkout master
+
+Patch Conflict Resolution
+-------------------------
+
+Two different patch conflict scenarios arise from time to
+time. Sometime after uploading a patch to https://gerrit.fd.io, the
+gerrit UI may show a patch status of "Merge Conflict."
+
+Or, you may attempt to upload a new patch-set via "git review," only to
+discover that the gerrit server won't allow the upload due to an upstream
+merge conflict.
+
+In both cases, it's [usually] fairly simple to fix the problem. You
+need to rebase the patch onto master/latest. Details vary from case to
+case.
+
+Here's how to rebase a patch previously uploaded to the Gerrit server
+which now has a merge conflict. In a fresh workspace cloned from
+master/latest, do the following:
+
+.. code-block:: console
+
+ $ git-review -d <*Gerrit change #*>
+ $ git rebase origin/master
+ while (conflicts)
+ <fix conflicts>
+ $ git rebase --continue
+ $ git review
+
+In the upload-failure case, use caution: carefully **save your work**
+before you do anything else!
+
+Rebase your patch and try again. Please **do not** re-download ["git
+review -d"] the patch from the gerrit server...:
+
+.. code-block:: console
+
+ $ git rebase origin/master
+ while (conflicts)
+ <fix conflicts>
+ $ git rebase --continue
+ $ git review
+
