hds: Normalize hds include file

To make it easier to generate the wrapper the HDS include file
format has changed from:

int
datFunc(type1 var1,
        type2 var2,
        int * status );

to

int
datFunc(type1 var1, type2 var, int *status);

Used a simple script:

cat /star/include/star/hds.h | perl -n -e 'chomp; s/\s*$//; s/^\s+//; s/\s+/ /g unless /^[\/\#]/; print $_.( $_ =~ /,$/ ? " " : "\n")'
