From 346d30a52f494d9f2e76e352a6ba8ca2ebdcf62f Mon Sep 17 00:00:00 2001 From: jsing <> Date: Sat, 25 Dec 2021 12:00:22 +0000 Subject: More consolidation of ASN.1 code. Consolidate various ASN1_item_* functions into asn1_item.c and the remaining NO_OLD_ASN1 code (not to be confused with the NO_ASN1_OLD code) into asn1_old.c. This is preferable to having many files, often with one or two functions per file. No functional change.
