* Efficient Abstract Syntax Notation One (ASN.1) implementation. This
* interface provides simple and efficient ASN.1 encoder and decoder.
+ *
* The encoder directly encodes BER encoded data blocks from variable
* argument list of ASN.1 types. Multiple trees can be encoded at once
* and multiple nodes can be encoded into the tree at once. By default
* References: ITU-T X.680 - X.693

+ * EXAMPLE
+ *
+ * silc_asn1_encode(asn1, buf,
+ * SILC_ASN1_SEQUENCE,
+ * SILC_ASN1_BOOLEAN(bool_val),
+ * SILC_ASN1_OCTET_STRING(string, string_len),
+ * SILC_ASN1_SEQUENCE_T(0, 2),
+ * SILC_ASN1_BOOLEAN_T(SILC_ASN1_EXPLICIT, 100, foo),
+ * SILC_ASN1_END,
+ * SILC_ASN1_OCTET_STRING_T(0, 1, string2, string2_len),
+ * SILC_ASN1_END, SILC_ASN1_END);
+ *
+ * Creates ASN.1 tree that looks something like:
+ *
+ * buf ::= SEQUENCE {
+ * bool_val BOOLEAN,
+ * string OCTET-STRING,
+ * [2] SEQUENCE {
+ * foo [100] EXPLICIT BOOLEAN }
+ * string2 [1] OCTET-STRING }
