POSIX 2008 TC2 requires <inttypes.h> to provide wchar_t

ok kettenis@ espie@

I am retiring my old email address; replace it with my OpenBSD one.

Our *int_fast{8,16}_t types are int/unsigned int, so SCN*FAST{8,16}
shouldn't include 'hh' or 'h'.

Contrary to C99's advice, C++ TR1 and C++ 11 require that <inttypes.h>
and <stdint.h> should unconditionally define all of their macros
regardless of whether the __STDC_*_MACROS macros are defined.

bulk build tested by landry

show more ...

Add wcstoimax(3) and wcstoumax(3).

ok miod@

Add comments to show which printf/scanf formats match which types

Update {PRN,SCN}*PTR defines to match types changes

Add lldiv(), imaxabs(), imaxdiv(), strtoimax() and strtoumax()

Add real C99 stdint.h and inttypes.h based on an initial version I did in
1997 (yes, really).

Sync with share/misc/license.template and add missing DARPA credit
where applicable.

Use an ISC-tyle license for all my code; it is simpler and more permissive.

move uint*_t to machine/types.h

Remove the advertising clause in my old license, it impedes free use
of the code as a large number of similar clauses makes it impossible
to write an ad for a product using the code...

inttypes.h as required by XPG4.2. Nothing uses this yet and all in-tree
sources should use the BSD-style types anyway.
