Fix: remove break in epoll loop of apps. thread
In *heavy* stress test with a large number of applications (> 7000 a
second), the manage application thread could starve the delete process
by breaking just after adding an application to the poll set.
Also, we've observed that somehow the application unregister process is
not done on most of the application by breaking the loop at each delete
from the poll set. We are still uncertain why but one theory is that
epoll detects that an I/O operation is ready (here a shutdown) and an
other subsystem of the session daemon uses that socket for I/O which
flags the poll event as "has been taken care of" thus the loop never
sees it because of that break.
The notify socket thread does not use a break between poll operation
which leads us to that conclusion with the manage apps thread.
We don't use epoll with edge-trigger thus a POLLERR/POLLHUP should
always be return as long as it's not taken care of.

Fix: don't fail on push metadata if no channel
The comments in the code explains it well but in a nutshell, this is an
acceptable race between the creation of the metadata on the consumer
side and the push metadata from the session daemon for that channel.
This race is resolved by either having the consumer requesting metadata
or the session is stopped which will in both situation push the metadata
to the consumer.
Without that fix, the session daemon flags the registry's metadata to be
"closed" which usually indicates that the consumer is not responding
leading to the consumer thread exiting in the session daemon.

Cases where the path given ended with '/.' or '/..' were not handled
properly using the utils_expand_path function and the resulting path
was still showing this end part. This fix aims to treat that last
part and 'expand' it as expected.

Fix: use non block waitpid to lookup child state
When daemonizing the session daemon, if the child fails *before* it
could set the recv_child_signal variable that indicates the parent to
exit, the parent process gets in an infinite loop never returning.
This commit fixes that by adding a non blocking waitpid() that monitors
the status of the child so it can exit if the child failed.

Introduce a new utils_partial_realpath function
This new utils function allows to resolve partially the paths
using realpath. As realpath(3) is not available to use for
unexistent paths, this function that allows to resolve partially
existent paths can be used in cases we don't know if the path
fully exists. It first resolves the existent part using
realpath(3) and then concatenate the unexistent part to it.
