I'm asking for permission to apply the following CEDET non-regression
bug fixes to the emacs-24 branch. They fix some pretty annoying bugs but
are so small that I think they should be safe to commit.

- Patch1: Fixes a bug where C++ system headers like "vector"
  are not recognized as C++ and hence parsing fails. The bug was that
  `enable-local-variables' was erronously set to 'nil' when loading
  those files, but it should be ':safe', so that the magic comments are
  recognized.

- Patch2: Without this fix, the interactive function
  `semantic-symref-symbol' simply does not work at all, so it cannot
  possibly make anything worse.

- Patch3: Move to beginning of completions when pressing TAB at the end
  of the Completions buffer.

- Patch4: Fixes a very annoying, long-standing bug were active buffers
  were killed when using GNU global and file was loaded through a
  symlink.
