The 'quit' Monitor command (implemented by do_quit()) calls
exit() directly, this is problematic under QMP because QEMU
exits before having a chance to send the ok response.

Clients don't know if QEMU exited because of a problem or
because the 'quit' command has been executed.

This commit fixes that by making do_quit() use
qemu_system_shutdown_request(), so that we exit gracefully.

Thanks to Paolo Bonzini <pbonzini@redhat.com> for suggesting
this solution.

Revert "PCI: Convert pci_device_hot_add() to QObject"

Short story: We don't want pci_add in QMP.  Long story follows.

pci_add can do two things:

* Hot plug a PCI NIC.  device_add is more general.

* Hot plug a PCI disk controller, and a drive connected to it.

  The controller is either virtio-blk-pci (if=virtio) or lsi53c895a
  (if=scsi).  With the latter, the drive is optional.  Use drive_add to
  hotplug additional SCSI drives.  Except drive_add is not available in
  QMP.

  device_add is more general for controllers and the guest part of
  drives.  I'm working on a more general alternative for the host part
  of drives.

Why am I proposing to remove pci_add from QMP before its replacement is
ready?  I want it out sooner rather than later, because it isn't fully
functional (errors and drive_add are missing), and we do not plan to
complete the job.  In other words, it's not really usable over QMP now,
and it's not what we want for QMP anyway.  Since we don't want it to be
used over QMP, we should take it out, not leave it around as a trap for
the uninitiated.

Dan Berrange confirmed that libvirt has no need for pci_add & friends
over QMP.

This reverts commit 7a344f7ac7bb651d0556a933ed8060d3a9e5d949.

Fix cross compilation

This patch enhances the algorithm which finds the correct settings for SDL.
For cross compilations (when cross_prefix is set), it looks for sdl-config
with cross prefix. Here is the complete search order:

$(cross_prefix}pkg-config              (old, only used for cross compilation)
${cross_prefix}sdl_config              (new, only used for cross compilation)
pkg-config                             (old, needs PATH)
sdl-config                             (old, needs PATH)

Cross SDL packages (or the user) now can simply set a link (for example
/usr/bin/i586-mingw32msvc-sdl-config -> /usr/i586-mingw32msvc/bin/sdl-config)
which allows cross compilations without PATH modifications.

Without the patch, configure and make (which calls configure) typically
need a non-standard PATH. Failing to set this special PATH results in
broken builds.
