Fix: take session list lock when listing tp
This is important since the list tracepoints command access the
application socket to ask the application for its TPs. The session list
lock protects the ordering of message for those sockets.
This was triggering out of order message between the session daemon and
an application thus triggering undefined behavior.

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.

The comments in the code explains it well but in a nutshell, this is an

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.

On the sessiond side, we need to ensure that the shared memory is writeable by

ftruncate and extend its size.
On the UST side, another commit needs to ensure that UST can read the shared

Buckets with many entries encountered in a hash table could cause it to
grow to a large size, beyond the scope for which this mechanism is

the hash table grows to larger size, split-counter node accounting is
expected to deal with resize/shrink rather than relying on an heuristic

Fix: set the health delta tcp timeout aware
The health check subsystem now initialized the time delta using the TCP
timeout. It takes the maximum value between our default internal delta
and the TCP timeout fetched by the lttcomm inet subsytem.

Get the maximum TCP timeout in sessiond
This actually just open some /proc files when calling
lttcomm_init_inet() and computes the maximum value a TCP timeout for
every possible operations (send/recv/connect).
This is the first patch to fix the health check issue of having a
smaller delta than the TCP maximum possible timeout.

Fix: don't report error if UST app dies
An application dying unexpectedly is a normal behavior so the execution
must continue and not report an error when sending commands onto the

Rename consumer socket fd to fd_ptr
By renaming this value, first the name as a better semantic and second
we are able to find every callsite that uses this variable thus making
sure we don't forget any assert or check made on it.

This is done so we don't copy the fd value of the consumer thus having a
