Note that this works only if --assume-binary is given. The use case
for the feature is PDF signature checking where the PDF specs require
that the detached signature is padded with zeroes.
* common/tlv.c (parse_ber_header): Protect agains integer overflow.

Although there is no concrete case where we use the (nhdr + length),
it is better to protect against this already here.

(cmp_canon_sexp_def_tcmp): New.
* common/t-sexputil.c (test_cmp_canon_sexp): Add a simple test.

Such code should actually go into libksba and we will eventually do
that. However, for now it is easier to keep it here.

Commit 91b826a38880fd8a989318585eb502582636ddd8 was not enough to
avoid all sign extension on shift problems. Hanno Böck found a case
with an invalid read due to this problem. To fix that once and for
all almost all uses of "<< 24" and "<< 8" are changed by this patch to
use an inline function from host2net.h.

We better do this once and for all instead of cluttering all future
commits with diffs of trailing white spaces. In the majority of cases
blank or single lines are affected and thus this change won't disturb
a git blame too much. For future commits the pre-commit scripts
checks that this won't happen again.
