d67336420d light: fix becoming primary when logfiles are damaged
When logfile replay aborts with an error, becoming primary would be
impossible.
Without this, repair would be only possible by complete destruction
of the resource.

A previous version of this patch introduced
/proc/sys/mars/allow_primary_when_damaged which would complicate
the sysadmin interface. People would be unsure what to do.

3eedff125d infra: fix comparison
Under weird circumstances, when a new symlink contents was just a
shortened version (prefix) of the old one, the symlink was not updated.

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.

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.
