LUDOC-266 protocol: Initial content for new repository

Initial content for the new 'protocol' repository.

The primary 'source' content in this repository is a collection of
text files ('*.txt') in the 'asciidoc' format, augmented with some
figures constructed with 'graphviz' ('*.gv'). 'asciidoc' will
produce '.html', '.pdf', and '.xml' (DocBook) files. 'graphviz'
('dot' actually) will produce '.png' files. The '.gitignore' file
lists these derived file extensions so the 'compiled' results will
not be a part of the repository contents, but instead will be build
afresh when needed.

In the 'figures' directory there is one '.gv' file (mkdir1.gv) that attempts to
capture some ideas about one state machine. It is an early effort at
this point.

The Makefile generates two commonly desirable output formats from
the source. These are .html and .pdf.
