We are going to support some addition IMGOPTS in python iotests like
in bash iotests. Similarly to bash iotests, we want a way to skip some

MEMFD_OPS is a weird Kconfig name given that it's not just memfd() that can
implement the ops.
Or, it's kvm that implements them to talk to memfd?

This patch is to improve the logic of QEMU main thread sleep code in
qemu_chr_write_buffer() where it can be blocked and can't run other
coroutines during COLO IO stress test.
Our approach is to put filter_send() in a coroutine. In this way,
filter_send() will call qemu_coroutine_yield() in qemu_c
