Libabigail doesn't yet support generic range types like in Ada.
Ranges are supported as a kind of implementation detail of array
types. But then its use like in the construct below is not supported:
type My_Int is range 0 .. 5;
function My_Function return My_Int;
Here, the integer type "My_Int" can take the discrete values that go
from 0 to 5. It's represented in the DWARF debug info as being a
range type of length 6 and whose underlying type has a size of 8 bits.
This patch adds support for a range type to be (de-)serialized from
and to abixml, diffed, diff-analyzed and diff-reported.
The ABIXML version number has been bumped from 2.1 to 2.2 accordingly.
