gpgsm: Strip trailing zeroes from detached signatures.
* common/ksba-io-support.c: Include tlv.h
(struct reader_cb_parm_s): Add new fields.
(starts_with_sequence): New.
(simple_reader_cb): Handle stripping.
* common/ksba-io-support.h (GNUPG_KSBA_IO_STRIP): New.
(gnupg_ksba_create_reader): Handle the new flag.
* sm/verify.c (gpgsm_verify): Use the new flag for detached
signatures.

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.
