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 Change-Id: I552a5645d5b7964d547f99b1336e2ac24e7c209f Signed-off-by: Nathan Skrzypczak <nathan.skrzypczak@gmail.com> Signed-off-by: Andrew Yourtchenko <ayourtch@gmail.com>

+# Startup Configuration {{'{#'}}syscfg}
+
+The VPP network stack comes with several configuration options that can be
+provided either on the command line or in a configuration file.
+
+Specific applications built on the stack have been known to require a dozen
+arguments, depending on requirements. This section describes commonly-used
+options and parameters.
+
+You can find command-line argument parsers in the source code by searching for
+instances of the `VLIB_CONFIG_FUNCTION` macro. The invocation
+`VLIB_CONFIG_FUNCTION(foo_config, "foo")` will cause the function
+`foo_config` to receive all the options and values supplied in a parameter
+block named "`foo`", for example: `foo { arg1 arg2 arg3 ... }`.
+
+@todo Tell the nice people where this document lives so that the might
+help improve it!
+
+## Command-line arguments
+
+Parameters are grouped by a section name. When providing more than one
+parameter to a section all parameters for that section must be wrapped in
+curly braces.
+
+```
+/usr/bin/vpp unix { interactive cli-listen 127.0.0.1:5002 }
+```
+
+Which will produce output similar to this:
+
+ <startup diagnostic messages>
+ _______ _ _ _____ ___
+ __/ __/ _ \ (_)__ | | / / _ \/ _ \
+ _/ _// // / / / _ \ | |/ / ___/ ___/
+ /_/ /____(_)_/\___/ |___/_/ /_/
+
+ vpp# <start-typing>
+
+When providing only one such parameter the braces are optional. For example,
+the following command argument, `unix interactive` does not have braces:
+
+```
+/usr/bin/vpp unix interactive
+```
+
+The command line can be presented as a single string or as several; anything
+given on the command line is concatenated with spaces into a single string
+before parsing.
+
+VPP applications must be able to locate their own executable images. The
+simplest way to ensure this will work is to invoke a VPP application by giving
+its absolute path; for example: `/usr/bin/vpp <options>`. At startup, VPP
+applications parse through their own ELF-sections (primarily) to make lists
+of init, configuration, and exit handlers.
+
+When developing with VPP, in _gdb_ it's often sufficient to start an application
+like this at the `(gdb)` prompt:
+
+```
+run unix interactive
+```
+
+## Configuration file
+
+It is also possible to supply parameters in a startup configuration file the
+path of which is provided to the VPP application on its command line.
+
+The format of the configuration file is a simple text file with the same
+content as the command line but with the benefit of being able to use newlines
+to make the content easier to read. For example:
+
+```
+unix {
+ nodaemon
+ log /var/log/vpp/vpp.log
+ full-coredump
+ cli-listen localhost:5002
+}
+api-trace {
+ on
+}
+dpdk {
+ dev 0000:03:00.0
+}
+```
+
+VPP is then instructed to load this file with the `-c` option:
+
+```
+/usr/bin/vpp -c /etc/vpp/startup.conf
+```
+
