Thomas Schoebel-Theuer 7d66938666 aio: fix portability to changed kernels / kthread implementation 
In the long term, mars_aio will be replaced anyway because it
uses userspace concepts like ioctx.

Don't use the internal kthread_stop_nowait() anymore.
It is too cumbersome to catch up with upstream development.

Thomas Schoebel-Theuer e7464b3c02 all: correct error code EIO 
The error code -EIO should always refer to a problem of
lower storage laysers. Thus MARS should not generate that
code itself, but other ones.

Thomas Schoebel-Theuer 917d5ae2d2 light: fix client shutdown on slow network 
On slow networks, the generic net_io_timeout is too long if you are
impatiently waiting for disconnect.

Change the io_timeout of the individual client brick to a short value.

Thomas Schoebel-Theuer 1295c43a7a infra: move io_timeout to generic interface 
This is needed for the next commit.
