Proposal: All constants should have UL suffix

[Stef Walter <stefw@redhat.com>]

All numeric constants in the specification section "A. Manifest
Constants" should have the suffix 'UL' on them. This allows the code
like this to return the correct result:

  sizeof(CKO_DATA)

Among other things, it also allows the constants to be passed correctly
to C varargs functions.

Since all document edits for this would be tedious. I'll just give a few
examples:

- #define CKU_SO         0
+ #define CKU_SO         0UL

and

- #define CKA_CLASS      0x00000000
+ #define CKA_CLASS      0x00000000UL

Above applies to every constant in the specification section "A.
Manifest Constants" as well obviously as the reference headers.

Cheers,

Stef
