deprecation of asn1_der_decoding_element

[Nikos Mavrogiannopoulos]

Hello,
 I'm trying to reduce the unnecessary code duplication in libtasn1.
One prominent candidate is asn1_der_decoding_element(). If I remember
well it was there to optimize few things when libtasn1 was very slow.
Would it make sense to deprecate it completely and make it an alias to
asn1_der_decoding()?  Are there any applications where this function
is being used that making it an alias to der_decoding would cause
issues?

regards,
Nikos
