Data usage limit label font size fixed

Browse Source 
Bug 6326750

The font size around the text was removed when its content is replaced.
This is WAI since the spans created from <font> html tags have a
SPAN_EXCLUSIVE_EXCLUSIVE flag. These are removed when their length
becomes 0. The bug came from a recent enforcement of this constraint.

The fix is to change the flags of these AbsoluteSizeSpan spans.

This CL also changes the code to avoid the creation of the int[] array.
