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.

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.

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

target/i386: Fix 32-bit wrapping of pc/eip computation
In 32-bit mode, pc = eip + cs_base is also 32-bit, and must wrap.
Failure to do so results in incorrect memory exceptions to the guest.
Before 732d548732ed, this was implicitly done via truncation to
target_ulong but only in qemu-system-i386, not qemu-system-x86_64.
To fix this, we must add conditional zero-extensions.
Since we have to test for 32 vs 64-bit anyway, note that cs_base
is always zero in 64-bit mode.

tcg: Reduce serial context atomicity earlier
Reduce atomicity while emitting opcodes, instead of later
during code generation. This ensures that any helper called
also sees the reduced atomicity requirement.
