[PATCH v4 0/7] Xprintf -> asprintf

I'm mostly resending since the mail server I used yesterday sent some
patches through, and sent others through a mail server in our DMZ that
seems to be failing at DNS, and thus didn't get them all through.
I've switched outgoing servers from the sun.com to the oracle.com
side, so hopefully this series will all get delivered.

Changes since v3:
 - Patch #1 & 2: Move Oracle line in COPYING to between Nvidia & Packard
	as noted by Simon
 - Patch #2: Add _X_ATTRIBUTE_PRINTF(*,0) for varargs versions
	as suggested by Jeremy
 - Patch #3: Add Jeremy's Reviewed-by

For those who didn't see the v3 summary, it said:
  This version adopts the middle road, as I suggested earlier today and we
  discussed on #xorg-devel IRC today.

  To the linker, the ABI will export the function Xasprintf() from the
  X server to modules.   To programmers, they simply have to include
  Xprintf.h (or os.h which includes it), and can then write code using
  asprintf(), and let autoconf & Xprintf.h determine whether it should
  mapped by a #define to Xasprintf() or simply use the platform's libc

  There's a bonus copyright notice update tacked on the front, so that
  the main asprintf() patch can update the COPYING file correctly.

I did also try removing the old API completely, but it turns out at least
the xf86-video-intel driver calls XNFprintf (I'd only searched for Xprintf
when I found no calls to it).   We may still be able to do that as part of
the Xserver 1.10 ABI/API changes, but should figure out first how drivers
should check for which version to call (check #ifdefs for server version?
ABI version?  autoconf check for existence of <xorg/Xprintf.h> ?).
