Peter Eisentraut d2f24df19b Clean up qsort comparison function for GUC entries 
guc_var_compare() is invoked from qsort() on an array of struct
config_generic, but the function accesses these directly as
strings (char *).  This relies on the name being the first field, so
this works.  But we can write this more clearly by using the struct
and then accessing the field through the struct.  Before the
reorganization of the GUC structs (commit a13833c35f), the old code
was probably more convenient, but now we can write this more clearly
and correctly.

After this change, it is no longer required that the name is the first
field in struct config_generic, so remove that comment.
