sm: Improve the octet string cramming for pkcs#12

Browse source

* sm/minip12.c (need_octet_string_cramming): New.
(tlv_expect_object, tlv_expect_octet_string): Run the test before
cramming.

* sm/minip12.c (ENABLE_DER_STRUCT_DUMPING): New but undefined macro
for debug purposes.
(bag_decrypted_data_p, bag_data_p): Use macro to allow dumping.

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.
