Mauro Carvalho Chehab 47459937be sphinx: parser_yaml.py: fix line numbers information
As reported by Donald, this code:

	rst_parser = RSTParser()
	rst_parser.parse('\n'.join(result), document)

breaks line parsing. As an alternative, I tested a variant of it:

	rst_parser.parse(result, document)

but still line number was not preserved. As Donald noted,
standard Parser classes don't have a direct mechanism to preserve
line numbers from ViewList().

So, instead, let's use a mechanism similar to what we do already at
kerneldoc.py: call the statemachine mechanism directly there.

I double-checked when states and statemachine were introduced:
both were back in 2002. I also tested doc build with docutils 0.16
and 0.21.2. It worked with both, so it seems to be stable enough
for our needs.

Mauro Carvalho Chehab d90555ef06 docs: parser_yaml.py: fix backward compatibility with old docutils
As reported by Akira, older docutils versions are not compatible
with the way some Sphinx versions send tab_width. Add a code to
address it.

Instead of printing line numbers from the temp converted ReST
file, get them from the original source.

Mauro Carvalho Chehab bb1e3629b2 docs: sphinx: add a parser for yaml files for Netlink specs
Add a simple sphinx.Parser to handle yaml files and add the
the code to handle Netlink specs. All other yaml files are
ignored.

The code was written in a way that parsing yaml for different
subsystems and even for different parts of Netlink are easy.

All it takes to have a different parser is to add an
import line similar to:

	from doc_generator import YnlDocGenerator

adding the corresponding parser somewhere at the extension:

	netlink_parser = YnlDocGenerator()

And then add a logic inside parse() to handle different
doc outputs, depending on the file location, similar to:

        if "/netlink/specs/" in fname:
            msg = self.netlink_parser.parse_yaml_file(fname)
