[Clam-devel] mac osx compilation fixed and build scripts refactoring

[Pau Arumi]

Dan and all, mac compilation is fixed, update your svn.

the problem was that in mac there is buildtools.py (in 
python/plat-mac/) which collided with our.

so the perfect time for a refactoring the too many helper files
(see below) into two new files. having less files and modules 
enables further simplifications of our build system.


commits 9986 and 9987 :

  * refactoring of build (python) helper scripts:
    - moved all buildtools functions and classes to
     clam_build_helpers.py
    (this fixes a bug: buildtools.py was a standard python module
     in mac)
    - moved all modconf functions and classes to
     clam_dependent_libs_checks.py
    - and so removed buildtools/ and modconf/ dirs

  * updated SConstruct and SConscripts after the buildtools and
    modconf refactoring


have fun!
