- Move newly exported APIs to "deprecated" libtasn1-dont.h header file.
The idea is that you should normally not use any of those functions
and types, and they are strong candidates to be removed in the future.
-- Export more APIs that were used by GnuTLS internally.
-- New public APIs:
+- Export more APIs that were used by GnuTLS internally to libtasn1-dont.h.
+- New public APIs (all in libtasn1-dont.h):
asn1_find_node function
asn1_find_up function
ASN1_TYPE_FIELD macro
