Eric Blake 9ffb827020 io: Yield rather than wait when already in coroutine ... The new qio_channel_{read,write}{,v}_all functions are documented as yielding until data is available. When used on a blocking channel, this yield is done via qio_channel_wait() which spawns a nested event loop under the hood (so it is that secondary loop which yields as needed); but if we are already in a coroutine (at which point QIO_CHANNEL_ERR_BLOCK is only possible if we are a non-blocking channel), we want to yield the current coroutine instead of spawning a nested event loop.
