Add a routine to "asn1.c" to translate ASN1_ERR_ values to strings. Use

that in the SNMP dissector.

Check the return values of ASN.1 routines in the LDAP dissector, and
have all the subroutines in that disesctor that can return error
indications return ASN1_ERR_ values.

Have the routines that can supply a pointer to a newly-created
protocol-tree item use the right type for items ("proto_item *", not
"proto_tree *", even though they are, at least currently, typedefs for
the same type), and use "proto_item" for the type of the item a pointer
to which is passed to those routines.

Before calling those routines, set the item pointer to null, in case the
routine fails.

Don't check the return value of "parse_filter_strings()" against -1 -
that routine can't return -1.
