Since drained nodes could be (partially or fully) broken in iallocator,
we ignore results from these nodes when building the cluster map in
preparation for sending it to the script.

This is a cheap change for the stable branch; ideally we should not
query them at all.

The patch also fixes a typo in iallocator.rst.

This patch adds a new opcode and lu for checking disk sizes. Currently
it does only top-level disk verification, and also doesn't check
primary/secondary node size mismatches (these two are added as TODOs in

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.
