inttypes: add PRI* and SCN* macros (LDEPS)

Browse source 
These macros cannot be tested properly until support for *printf and
*scanf is added (support for *printf currently exists but with a
temporary implementation), so this is LDEPS.

The size of the types has been checked though, so the definitions here
should be correct, the rest is printf/scanf logic.
