texi2dvi: More HeVeA support

[Akim Demaille]

I hope this can still make it in the future texi2dvi!

Index: ChangeLog
from  Akim Demaille  <address@hidden>

        Use hevea more like we use tex itself, no longer as a tool
        that does everything magically.
        * util/texi2dvi (run_hevea): Remove trailing spaces in the
        output.
        (run_tex_suite): Change to the working directory here, no longer
        in...
        (run_core_conversion): here, so that even when running hevea where
        are in the working directory.
        No longer call cd_orig, do it...
        (run_tex_suite): here.
        (run_hevea): Pass verbose flags to it when --debug.
        (run_tex_suite): Since we now want to run the whole suite of tools,
        including bibtex, with hevea, use run_core_conversion, not
        run_tex.
        (run_core_conversion): Now call run_tex.
