Win32 does not support line-buffering, but it allows
unbuffered output.

Unbuffered output is a good approximation. For typical output
statements which usually end with '\n', it's even identical.

Buffered output is unusable for program traces because of
its large delay.

This fixes an observed failure to detect madvise() on Linux.

To avoid similar issues, all other tests that use NULL but don't already
have stddef.h (or another header that is defined to provide NULL,
such as stdio.h, unistd.h, or time.h) are also fixed.

The LTTng UserSpace Tracer formerly used TPPROTO() and TPARGS() instead
of TP_PROTO() and TP_ARGS() like the kernel uses.  This has been changed
so QEMU needs to follow.

I am not aware of a graceful way of making the transition but since no
one complained that the UST build is broken, it should be fine to just
switch over without compatibility for old UST headers.  The newer UST
headers are shipping in distro packages so it is realistic to make this
change now.

Since version 4.4.x, gcc supports additional format attributes.
    __attribute__ ((format (gnu_printf, 1, 2)))
should be used instead of
    __attribute__ ((format (printf, 1, 2))
because QEMU always uses standard format strings (even with mingw32).

The patch replaces format attribute printf / __printf__ by macro
GCC_FMT_ATTR which uses gnu_printf if supported.

It also removes an #ifdef __GNUC__ (not needed any longer).
