Subject: [PATCH 04/19] Add libtomcrypt headers
Same as the previous patch - the header file dependencies do not allow
otherwise.
(Reviewing this in detail is probably premature, we are considering
replacing the implementation by something based on libgcrypt, which is
more actively maintained and has been probably more thorouhgly examined
for vulnerabilities.)
