Nathan Skrzypczak 1e167a4aad docs: make docs build incremental
This patch makes the `make docs` directive incremental
avoiding re-running the siphon when the source hasn't
changed, and leveraging sphinx internal cache.
It adds a `make rebuild-docs` directive for cases where
this caching logic might break, e.g. in CI.
The virtualenv doesn't also get recreated on each build,
which might be enough when writing docs, provided
automated process leverage its rebuild counterpart.

Type: improvement

Building VPP Documents

These instructions show how the VPP documentation sources are built.

To build your files, you can either Create a Virtual Environment using
virtualenv, which installs all the required applications for you.

Create a Virtual Environment using virtualenv
============================

For more information on how to use the Python virtual environment check
out https://packaging.python.org/guides/installing-using-pip-and-virtualenv

Get the Documents
------------------------------

For example start with a clone of the vpp.

$ git clone https://gerrit.fd.io/r/vpp
$ cd vpp

Install the virtual environment
----------------------------------------------

$ python -m pip install --user virtualenv
$ python -m virtualenv env
$ source env/bin/activate
$ pip install -r docs/etc/requirements.txt
$ cd docs

Which installs all the required applications into it's own, isolated,
virtual environment, so as to not interfere with other builds that may
use different versions of software.

Build the html files
----------------------------

Be sure you are in your vpp/docs directory, since that is where Sphinx will
look for your conf.py file, and build the documents into an index.html file

$ make html

View the results
------------------------

If there are no errors during the build process, you should now have an
index.html file in your vpp/docs/_build/html directory, which you can
then view in your browser.
