qrexec: in write_stdin, remove dependency on write size
...
Previous code could barf when write was partial; probably can happen
only if we increase vchan buffer size, but it is better isolated now.

qrexec: when forgetting about a client/process, flush buffered data
...
We need to spawn a child to take care of buffered data flushing, if there
is any. Expensive, but should be needed rarely.

qrexec: handle buffered writes correctly
...
In case when we have a buffered write, always append to the
buffer, even if the pipe happens to be writable now. If not,
in case of certain tight race we might end up writing buffered data in
wrong order.
