cipe-1.6.0 - 3 patches solving 3 problems

Hi All,
The following three patches solve three problems I encountered when building
CIPE 1.6.0, one of which is a serious bug.
-1- conf/Makefile-top.in: Wrong switch when invoking autoconf from top
Makefile.
    "-l" should be replaced by "-I". The same applies also to cipe-1.5.x
-2- configure.in: Dependency on an undocumented autoconf 2.13 behaviour that
    fails using later versions of autoconf.
    The result is that config.h is placed in the root directory instead of
    in the BUILD-directory. The same applies also to cipe-1.5.x
-3- cipe/device.c
    When both the cipcb and cipdb modules are loaded in the same 2.6 kernel,
    the kernel will panic when the cipxb modules are unloaded:
 The first will free memory for both drivers, for example:
 ..
 Feb  5 15:48:34 .. kernel: cipcb: freeing cipdb0
 Feb  5 15:48:34 .. kernel: cipdb: freeing cipdb0
 Feb  5 15:48:37 .. kernel: cipcb: freeing cipcb0
    and the kernel panics..
