This patch unifies the search for external script to always go through
utils.FindFile and implements in that function a restriction on valid
chars in file names and (additionally) that the passed name is the
basename of the final (absolute) name.

In most uses of LUQueryNodes, we don't take a lock. This means that the
instance data is not protected across GetInstanceList and
GetInstanceInfo, and this can lead to instances not existing anymore.

Switching to GetAllInstanceInfo means that we get a single,
semi-consistent snapshot (since instances can still be modified, but
it's much better).

Patch 4352bf6d changed RAPI docs to RST from the previous SGML format
(the last file to be converted to RST).

However, it didn't add rapi.rst to the docrst Makefile variable, and as
such rapi.html was neither build nor shipped in the archive. We fix this
and we also distribute doc/rapi-resources.gen since otherwise “make
distcheck” has issues (since this file is built and thus lives in _built
whereas rapi.rst is shipped and lives in topsrcdir).

Note: yes, this means that no 2.0 release until now had a rapi.html file
(in the .tar.gz archive).

This patch removes the quotes from CommaJoin and converts most of the

param, we can remove these, thus simplifying slightly a few calls.
