Overhaul the audit filename handling

This patchset has some important changes from the previous revision, namely a fix from Al Viro (included in 2/5) that resolves a boot panic on some systems as well as some smaller, less noteworthy fixes found in the linux-next announcement thread from January 20th (refcount bump in __audit_reusename() and a inode type in __audit_inode()).

This patchset still needs some additional testing to verify that the audit code still functions properly (the minor fixes mentioned above) and there is an additional patch from Al that should be included as well, but I wanted to post this and push the series to the audit next branch quickly since a number of folks were affected by the boot panic.
