Some heavy changes today:
  * Removed duplicate function checks from configure.in.
  * Added extra magic to Makefile.modules so that the module Makefiles

    plugins with the same version number. A nasty consequence is that you
    need to rebuild your tree after midnight if you are using a CVS tree :-)
  * Got rid of modules_export.h by #defining exported functions in the same
    header as their prototype.

    there are less and less files to include, and renamed common.h to
    <videolan/vlc.h>.
  * First modifications to the module handling system towards my ultimate
    goal to get rid of the *_Probe functions. Got rid of TestMethod and
    TestCPU, as well as src/misc/tests.c.
