  - preallocate string size to avoid too many realloc

gstvalue.c ::
  - replace some for() iterations by a while(i--) which is faster.
  - replace 
for (n = 0; n < size; n++) {
       kid = gst_value_array_get_value (value, n);
       fixed &= gst_value_is_fixed (kid);
     }

by 
    for (n = 0; n < size && fixed; n++) {
       kid = gst_value_array_get_value (value, n);
       fixed &= gst_value_is_fixed (kid);
     }

to exit the loop when 'fixed' turned to be false.
