experimenting with slave output capture via a pipe
Merge branch 'master' into slave-output-capture
Experimental RHEL packaging.

Well, this .spec file should magically allow us to have RPM packages for
the Cocaine Core, probably.
Slave output capturing.

Capture slave output and dump it to the storage in case this given slave
had died unexpectedly.

Reroute stdio descriptors only in children.

Do not reroute stdio descriptors in both parent and child, as it's
messing with the stdout logging and, in general, is a bad idea.
Put crashlogs in a proper namespace.

Fixed a typo with crashlogs namespace name. Also complain if a slave
died unexpectedly and there's no output to dump.
Detach sessions on explicit suicide too.

When the slave is unable to initialize, but already has a session
assigned to it, then this session has to be detached, like in other
cases (disconnect, timeout).
