make dissect_ber_choice take a guint* that will return the

index of the branch taken or -1  to make prettifications easier to implement.


change the signature of dissect_ber_choice and rename it to dissect_ber_CHOICE to catch all
occurences of the use of this function

update asn2eth to use the new name/signature

update all occurences of this function to the new name and new signature.
