* g10/keylist.c (print_fingerprint): Print a warning after a PGP-2
fingerprint.

Printing all zeroes for a PGP-2 (v3 key) fingerprint has the problem
that frontends (or the user) may use that fingerprint to lookup a key
and gpg will return all PGP2 keys. They may then show a different
PGP-2 key than the one actually used for a signature. This is worse
than displaying a weak fingerprint.

This is a backport of 76c8122adfed0f0f443cce7bda702ba2b39661b3 from
master to the STABLE-BRANCH-2-0
On the STABLE-BRANCH-2-0, we may also want to patch g10/seckey-cert.c,
but that has not been done in this patch.
This fix extends commmit 0835d2f44ef62eab51fce6a927908f544e01cf8f.

This fixes sign extension on shift problems. Hanno Böck found a case
with an invalid read due to this problem. To fix that almost all uses
of "<< 24" and "<< 8" are changed by this patch to use an inline
function from host2net.h.

MD5 is considered broken for a long time now. To make it easier for
users to notice that a listing shows a v3 key, the fingerprint is now
displayed as 16 zero bytes unless --allow-weak-digest-algos is active.

to libgcrypt functions, using shared error codes from libgpg-error,
replacing the old functions we used to have in ../util by those in
../jnlib and ../common, renaming the malloc functions and a couple of
types. Note, that not all changes are listed below becuause they are
too similar and done at far too many places. As of today the code
builds using the current libgcrypt from CVS but it is very unlikely
that it actually works.
