Adding package for ASN.1 to C compiler asn1c from Lev Walkin version
0.9.24 into lang/asn1c.

The asn1c is a free, open source compiler of ASN.1 specifications into C
source code. It supports a range of ASN.1 syntaxes, including ISO/IEC/ITU
ASN.1 1988, '94, '97, 2002 and later amendments. The supported sets of
encoding rules are

  * BER: ITU-T Rec. X.690 | ISO/IEC 8825-1 (2002) (BER/DER/CER).
  * PER: X.691|8825-2 (2002) (PER).
  * XER: X.693|8825-3 (2001) (BASIC-XER/CXER).

The compiler was written specifically to address security concerns while
providing streaming decoding capabilities.
