To minimize code duplication, epoll is hooked into aio-posix's
aio_poll() instead of rolling its own. This approach also has both
compile-time and run-time switchability.
1) When QEMU starts with a small number of fds in the event loop, ppoll
is used.
2) When QEMU starts with a big number of fds,
This allows AioContext users to check the enable/disable state of
external clients.

v4: Rebase onto master (with aio_disable_external):
Don't use epoll if aio_external_disabled(ctx);
Change assert on epoll_ctl return code to disable epoll;
Rerun benchmark;
v3: Remove the redundant check in aio_epoll_try_enable. [Stefan]
v2: Merge aio-epoll.c into aio-posix.c. [Paolo]
This is the place to initialize platform specific bits of AioContext.

Commit 934659c switched the iotests to run qemu-io from a bash subshell,
in order to catch segfaults. This method is incompatible with the
current valgrind_qemu_io() bash function.
Move the valgrind usage into the exec subshell in _qemu_io_wrapper(),
while making sure the original return value is

There are several sanity checks for the 'blockdev-snapshot' command,
but none covers the use of a file BDS as the overlay node.
{ 'execute': 'blockdev-add', 'arguments':
{ 'options': { 'driver': 'qcow2',
'node-name': 'new0',
'file': { 'dr
This addresses scenarios where the overlay node of the
'blockdev-snapshot' parameter is a child of an existing node,
such as this one:
{ 'execute': 'blockdev-add', 'arguments':
{ 'options': { 'driver': 'qcow2',
'node-name': 'new0',
'file': { 'driver': 'f

Commit 934659c switched the iotests to run qemu and qemu-nbd from a bash
subshell, in order to catch segfaults. Unfortunately, this means the
process PID cannot be captured via '$!'. We stopped killing qemu and
qemu-nbd processes, leaving a lot of orphaned, running qemu processes
