unrelated changes that ended up being more trouble to commit separate...
- removed BLI_split_dirfile(), was nasty, occasionaly modifying the source string, it could create directories and used the $CWD in some cases. was only used in 2 places in filesel.c, if this gives problems can address without bringing back this function.
renamed BLI_split_dirfile_basic --> BLI_split_dirfile
- view3d_operator_needs_opengl was being called for offscreen render when it wasnt needed.
rename BKE_get_image_export_path() to BKE_rebase_path() and take a filename arg rather then an image.
obj export file copy was also not working because of a missing import.
- added an option to BLI_convertstringframe and BLI_convertstringframe_range to add digits if not found.
- removed BLI_convertstringframe where its obviously not needed - such as loading movies and sounds.
* added renamed files in revision 25337
* renamed BLI_util.h -> BLI_path_util.h for consistency
* cleanup of #includes: removed BLI_blenlib.h in favour of direct includes of the needed headerfiles in a few places.
* removed debug print in sequencer.c
* added missing include in blenkernel/blender.c -> bad dependency, needs to be fixed still
