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.

There is a race between application startup and sessiond startup, where there
is an intermediate state where applications can SIGBUS if they see a zero-sized
shm, if the shm has been created, but not ftruncated yet.
On the sessiond side, we need to ensure that the shared memory is writeable by
applications as long as its size is 0, which allow applications to perform
ftruncate and extend its size.
On the UST side, another commit needs to ensure that UST can read the shared
memory file descriptor with a read() system call before they try accessing it
through a memory map (which triggers the SIGBUS if the access goes beyond the
file size)

Fix: hash table growth (for small tables) should be limited (v2)
Buckets with many entries encountered in a hash table could cause it to

the hash table grows to larger size, split-counter node accounting is
expected to deal with resize/shrink rather than relying on an heuristic
based on the largest bucket size.
This is fixing an issue where we see hash tables sometimes reaching 65k

1000 entries and then removing all of them, done in a loop (random

Fix: consumer: 64-bit index for relayd rather than 32-bit (v2)
Relayd "unique" ids wrap every 32-bit, and in some cases, negative
values are considered as error.
Change this to make the error value specifically -1ULL, use a direct
comparison (since we use an unsigned 64-bit integer, comparison with 0
becomes incorrect).
Since we now use a 64-bit ID, it is assumed to _never_ wrap-around
(remember, value -1ULL is an _error_). Therefore,
consumer_add_relayd_socket() can become much more strict than it was:
instead of accepting re-use of net_seq_idx, we can now assert that upon
LTTNG_STREAM_CONTROL socket, we have indeed allocated a relayd object,
and upon LTTNG_STREAM_DATA, we have found a relayd object.

Fix: send per-pid session id in channel creation
The registry indexing for per-pid sessions is done with a per-pid
session id. So for per-pid buffers, we need to send the per-pid session
id as well as the global session id to the consumer in order to give it
enough information if it needs to request metadata later.
This patch adds the session_id_per_pid to the channel creation message
and to the consumer. When the sessiond receives a metadata_request,
depending on the buffer type (per-pid or per-uid), it selects the right
id to do the registry lookup.
