This big patch converts the documentation build system to sphinx
(http://sphinx.pocoo.org/

). Since that uses reStructuredText sources
too, there is no change (yet) in the documents themselves, just in the
build system.

As before, the docs are pre built by the maintainer, and the end-user
doesn't need sphinx or other rst tools to build the docs. Note that we
are not distributing PDFs, so building that will require the tools.

The docs will be stored under doc/html and the build system also need an
extra directory doc/build. These are considered (by automake)
maintainer-related objects and are removed at maintainer-clean time.

The patch also fixes some small issues: add a docpng variable, add
doc/api (also generated by maintainer) in maintainer-clean-local, etc.

Since 8.0.6 and lower have issues that break Ganeti's usage of drbd,
this patch notes the required version of DRBD.

This patch does:
  - add drbd8 information to the docs (the new disk template, examples,
    etc.)
  - fixes a section header to make it more clear
  - update the NEWS file by changing format (format taken by looking at
    /usr/sharea/doc/*/NEWS.gz) and adding more information on changes
    since beta1

This duplicates some code from the DRBDev class, but not very much, and
it will be expanded with the new functionality available for the 8.x
version. Currently the code is not accessible outside the module.

This patch introduces a dependency on the pyparsing module.

This is more in line with the other document names.

Also, change the title to simply "Ganeti installation tutorial".

In case one installs from source, make, tar and gzip are also needed. tar and
gzip are almost always installed, but make not, so let's add a note about that.

Also remove a '>' in the apt-get install example so copy-paste works.

This removes the section on packages from installing.sgml (until we have
packages) and adds/corrects informations about using the startup script.

It also adds notes about the ``--master-netdev`` option, which one needs
to use if the node doesn't have an interface named xen-br0 (or if it's
not the interface wanted for external access).

This changes installing.sgml, adding details about required software and
OS instances. It also updates INSTALL and README to correspond with the
sgml manual.
