Harmless bug: a return value should be set also in case of error exit

Cleanup of unused variables

Added TB09 functional, from libxc, courtesy of Eric Germaneau. 
Added two small files from libxc. Compile with -D__LIBXC, link with libxc:
-L/dir/where/libxc/is -lxcf90 -lxc
User guides updated with a reshuffling of names: contributors to all of QE
(in particular, most functionals) are listed in the user guide of QE and
not in the one of PW. make.depend updated

This is just to avoid that the work done is lost. It should be a first step 
towards better organization of XC functionals. We should seriously consider
one of the following options:
1. move to libxc, getting rid of all duplicated functionals, keeping only
   those that are not available in libxc;
2. add the possibility to use any functional from libxc (currently only a few
   can be used). This may require serious restructuring work in our XC
   functional (il-)logic, that has become clumsy, obscure and redundant

bands.x writes a file filband.'gnu' with bands in plottable format (by gnuplot
or xmgrace or whatever plotting program). Saves a step (the plot_bands.x run)
when plotting bands: useful for tutorials ...

improving the helpdoc utility so as to work not only under the svn but also for the espresso tarball

Fix to some OpenMP wierdness in Intel compilers (GS).

Minor changes in TDDFPT. The turboDavidson code works properly with the Environ module (tested).

Added an example how to use turboDavidson with the Environ module.

Meta-GGA functionals have their own index, distinct from the one used to 
classify GGA ones. Some cleanup in functionals-related stuff. Much more is
badly needed.

There are too many interface functions computing exchange and correlation.
Functions exc_t, vxc_t moved out of module funct to the only package where 
they are used (atomic). They should be replaced by xc, xc_spin sooner or
later.
