  1. meson, xen: fix condition for enabling the Xen accelerator 

    A misspelled condition in xen_native.h is hiding a bug in the enablement of
Xen for qemu-system-aarch64.  The bug becomes apparent when building for
Xen 4.18.

While the i386 emulator provides the xenpv machine type for multiple architectures,
and therefore can be compiled with Xen enabled even when the host is Arm, the
opposite is not true: qemu-system-aarch64 can only be compiled with Xen support
enabled when the host is Arm.

Expand the computation of accelerator_targets['CONFIG_XEN'] similar to what is
already there for KVM.

  2. xen: fix condition for skipping virtio-mmio defines 

    GUEST_VIRTIO_MMIO_* was added in Xen 4.17, so only define them
for CONFIG_XEN_CTRL_INTERFACE_VERSIONs up to 4.16.

  4. block: Fix AioContext locking in qmp_block_resize() 

    The AioContext must be unlocked before calling blk_co_unref(), because
it takes the AioContext lock internally in blk_unref_bh(), which is
scheduled in the main thread. If we don't unlock, the AioContext is
locked twice and nested event loops such as in bdrv_graph_wrlock() will
deadlock.

  5. docs: clean-up the xenpvh documentation 

    I noticed the code blocks where not rendering properly so thought I'd
better fix things up. So:

  - Use better title for the machine type
  - Explain why Xen is a little different
  - Add a proper anchor to the tpm-device link
  - add newline so code block properly renders
  - add some indentation to make continuation clearer
