#8 compile fixes for kernel >= 2.6.13

[Jens Maus]

Since kernel version 2.6.13 the "crypto_tfm_ctx()" inline function
is part of the linux kernel sources and therefore conflict with the
own definition of cipe:

-- cut here --
In file included from /usr/src/cipe-linux/2.6.13-gentoo-i386-cb/
cipe.h:161,

include/linux/crypto.h:297: error: previous definition of
'crypto_tfm_ctx' was here
-- cut here --

However, this can be easily solved by excluding the relevant
definition in cryptoapi.h with the following patch:

However, I will attach my complete "cipe.patch" file which should
make the current set of sources in the CVS automatically
compilable for kernel 2.6.13, including my previous patch to make
cipe work with 2.6.12 kernels.

Hope to see my patches be applied against the latest CVS
sources soon....
