Merge _ksba_keyinfo_to_sexp into cryptval_to_sexp

* src/keyinfo.c (cryptval_to_sexp): Add mode 2 support suitable to
  replace parse keyinfo data.
* src/keyinfo.c (_ksba_keyinfo_to_sexp): Use new cryptval_to_sexp
  mode dedicated to keyinfo parsing.

--
_ksba_keyinfo_to_sexp and cryptval_to_sexp share lots of common code.
Merge them to be less error prone.

Adapt mkoidtbl script to newer dumpasn1 database format

Debian jessie currently has dumpasn1 version 20130608-1. It uses
dumpasn1.cfg with slightly different format:

OID = 0 2 262 1 10
Comment = Deutsche Telekom
Description = Telesec

Adapted mkoidtbl to work on both types of files.
