* sm/encrypt.c (gpgsm_encrypt): Unify use of RC and ERR.
* sm/sign.c (gpgsm_sign): ditto.
--
Initially we didn't used the gpg_error_t thingy and while migrating
we sometimes used RC and ERR for tracking the error. This is pretty
error prone and thus we better remove it (after 20 years).
* g10/sign.c (sign_file): Initialize gcry_md_hd_t to NULL.
--
There are several jumps to leave before gcry_md_open is called so
md should be initialized to NULL to avoid calling gcry_md_close
on an uninitalized variable.

(scan_isodatestr): Fallback to isotime2epoch_u64.
--
This mainly helps on 32 bit Windows. For Unix we assume everyone is
using 64 bit or shall wait until the libc hackers finally provide a
time64_t.

tlv_expect_sequence.

--
This patch improves the BER parser by simplifying it. Now tlv_next
pops off and thus closes all containers regardless on whether they are
length bounded or ndef. tlv_set_pending is now always used to undo
the effect of a tlv_next in a loop condition which was terminated by a
nesting level change.
Instead of using the length as seen in the decrypted container we now
remove the padding and let the BER parser do its work. This might
have a negative effect on pkcs#12 objects which are not correctly
padded but we don't have any example of such broken objects.

* m4/autobuild.m4 (AB_INIT): Add username.
--
The old autobuild diagnostics show up in build logs. What they are
missing is an information on the user who triggered a build. EMAIL is
a common thing to denote the actual user using a service account.
* g10/keygen.c (parse_expire_string_with_ct): Use new function
scan_secondsstr.
(parse_creation_string): Ditto.

Noet that we cap the seconds at the year 2106.

* sm/minip12.c (_tlv_push): Handle NDEF more correctly.
(tlv_expect_octet_string): Do not bail out on NDEF.
(dump_tag_info): Print some more infos.
--
We do not have a complete test case for this. We need to further
analyze T6752 to see what Mozilla is doing here. In any case with
this patch we get a bit further and don't bail out at the ndef.

(decrypt_block): Ditto.
(parse_bag_encrypted_data): Parse the optional prf part and get the
hmac algorithm.
(parse_shrouded_key_bag): Ditto.
(p12_build): Pass SHA1 for digest_algo.
* sm/t-minip12.c (run_one_test): Print failed values in verbose mode.
* tests/cms/samplekeys/nistp256-openssl-self-signed.p12: New.
* tests/cms/samplekeys/Description-p12: Add this one.
* tests/cms/Makefile.am (EXTRA_DIST): Ditto.
--
This supports the modern algorithms, i.e. using SHA256 for the KDF
which is the default in openssl unless the -legacy option is used.

This bug was exhibited by importing a gpgsm exported EC certificate.
We use an extra test instead of retrying to allow retruning an error
from malloc failure. And well, for easier reading of the code.

In particular when using a dotlock file for protecting the spawning
and several processes try to spawn the agent or another component, we
often run into long delays. The solution is to is to exponential
backoff and also to reduce the initial delay from 50ms to 4ms. We
further limit the maximum wait period to about 2 seconds and then
repeat at intervals of 512, 1024 and 2048ms. In the wait-forever case
we add a small random value to have different intervals per process.

For testing this code snippet in the spawning function might be
useful:
const char *s;
if ((s=getenv("hold_gpg_file")))
while (!gnupg_access (s, F_OK))
gnupg_sleep (1);
