CCM is only meant for packet mode where the length of the input is known in
advance. Since it is a packet mode function, CCM only had one function that
performs the protocol.
However, incremental authentication is usefull in some usecases. It also
ensure some kind of coherencies when processing with a given authentication
mode or another. To achieve this aim, this commit adds the following functions:
ccm_init()
ccm_add_aad()
cm_add_nonce()
ccm_process()
ccm_done()
ccm_reset()
as well as the data structure
ccm_state

This entails:
• Using pdflatex to influence the modification/creation timestamp in
the resulting PDF
• Replacing the unique ID with 0/0
• Using the timestamp from crypt.tex instead of the current date/time

This change is necessary because for Multi-Arch Debian packages,
non-arch-dependent files need to have the same checksum, which is not
guaranteed without this commit. See http://bugs.debian.org/734109
"make clean" was deleting "doc/*.pdf", despite the fact that there
were two comments (one above and one below) stating that it did not.
Since doc/crypt.pdf is checked into git, running "make clean" made my
git state dirty, which seems undesirable.
I took sort of a compromise position and had "make clean" continue to
delete any other .pdf files in doc (such as refman.pdf), but
explicitly not delete crypt.pdf.
This line:
rm -f `find . -type f | grep "[.]lo" | xargs`
was deleting crypt.lof, which seemed undesirable. One solution would
be to end the grep expression with "$", but it seemed more
straightforward just to pass "-name" to "find", rather than piping
through grep.
