This patch implements proposal from Paolo to handle system reset when
the guest is not running.

"After a reset, main_loop_should_exit should actually transition
to VM_STATE_PRELAUNCH (*not* RUN_STATE_PAUSED) for *all* states except
RUN_STATE_INMIGRATE, RUN_STATE_SAVE_VM (which I think cannot happen
there) and (of course) RUN_STATE_RUNNING."

Actively redefining 'inline' is wrong for C++, where gcc has an
extension 'inline namespace' which fails to compile if the
keyword 'inline' is replaced by a macro expansion.  This will
matter once we start to include "qemu/osdep.h" first from C++
files, depending also on whether the system headers are new
enough to be using the gcc extension.

But rather than just guard things by __cplusplus, let's look at
the overall picture.  Commit df2542c7 in 2007 defined 'inline'
to the gcc attribute __always_inline__, with the rationale "To
avoid discarded inlining bug".  But compilers have improved since
then, and we are probably better off trusting the compiler rather
than trying to force its hand.

So just nuke our craziness.

If io_channel_send_full gets QIO_CHANNEL_ERR_BLOCK it
and has already sent some of the data, it should return
that amount of data, not EAGAIN, as that would cause
the caller to re-try already sent data.

Unfortunately due to a previous rebase conflict resolution
error, the code for dealing with this was in the wrong
part of the conditional, and so mistakenly ran on other
I/O errors.

This be seen running

   qemu-system-x86_64 -monitor stdio

and entering 'info mtree', when running on a slow console
(eg a slow remote ssh session). The monitor would get into
an indefinite loop writing the same data until it managed
to send it all without getting EAGAIN.

This reverts commit 34689e20.

Marc-André Lureau provided the following commentary: "It looks like if
a the slave is opened, then Linux will buffer the master writes, up to
a few kb and then throttle, so it's not entirely blocked but eventually
the guest VM dies.  However, not having any slave open it will simply let
the write go and discard the data.  At least, virt-install configures
a pty for the serial but viewers like virt-manager do not necessarily
open it.  And, if there are no viewers, it will just hang.  If qemu
starts reading all the data from the slave, I don't think interactions
with other slaves will work. I don't see much options but to close the
slave, thus reverting this patch."

Recent Fedora complains while compiling ui/sdl.c:

    /usr/x86_64-w64-mingw32/sys-root/mingw/include/winsock2.h:15:2: warning: #warning Please include winsock2.h before windows.h [-Wcpp]

And with this patch we dutifully obey.

Stefan Weil:

Without that patch, windows.h will include winsock.h
(which conflicts with winsock2.h) when compiling sdl.c.

Normally we define WIN32_LEAN_AND_MEAN, and
windows.h won't include winsock.h.

include/ui/sdl2.h and ui/sdl.c undefine that macro,
so the order of the include files is important.
