Casing of number literals in ada-mode

[jemarch]

Hi.

Appended is a little patch that makes ada-mode to not case number
literals to avoid situations like:

      subtype U32 is range 16#0000_0000#..16#Ffff_Ffff#;

Note the Ffff_Ffff.

        * progmodes/ada-mode.el (ada-in-numeric-literal-p): New function.
        (ada-adjust-case): Don't adjust case in hexadecimal number
        literals.
