Fix (?): Delete 'ip-pda 6' (id-pda-pseudonym) because it does not exist
in RFC 3039.
Also change Perl scripts to put auto-generation warning in the
first lines of the file.
abort with errors if no name is defined for some object, which was the
case for 'pilotAttributeType 27'.
Also avoid this very situation by assigning the name
'pilotAttributeType27'.
Modify obj_dat.pl to take its files from the command line. Usage is now
perl obj_dat.pl objects.h obj_dat.h
this should avoid redirection shell escape problems under Win32.
