Fix: UST subbuffers silently dropped on moderate trace traffic
Well, it looks like we really screwed up on this one.
lttng-tools commit
02b3d1769d5f8a33e4109b1e681141c9295dfda6 introduced
an important regression for lttng-ust tracing in the consumer daemon:
after reading a sub-buffer, a check has been added to see whether there
are more sub-buffers available to read, and if it is the case, it
ensures the wakeup pipe will be awakened again.
The issue lies in the use of ustctl_put_next_subbuf() in this check.
This acts as if the sub-buffer has been read, when in reality it has not
been read. It therefore trashes the data contained by this sub-buffer.
This check should use ustctl_put_subbuf(), which does not move the
consumer position.
This is a severe bug, and the fix needs to be applied to stable-2.6,
stable-2.5, and stable-2.4.

Fix: filter attach vs event enable race
In order to correctly handle the use-case where events are enabled
_after_ trace is started, and _after_ applications are already being
traced, the event should be created in a "disabled" state, so that it
does not trace events until its filter is attached.
This fix needs to be done both in lttng-tools and lttng-ust. In order to
keep ABI compatibility between tools and ust within a stable release
cycle, we introduce a new "disabled" within struct lttng_ust_event
padding (previously zeroed). Newer LTTng-UST checks this flag, and
fallback on the old racy behavior (enabling the event on creation) if it
is unset.
Therefore, old session daemon works with newer lttng-ust of the same
stable release, and vice-versa. However, building lttng-tools requires
an upgraded lttng-ust, which contains the communication protocol with
the new "disabled" field.
This patch should be backported to stable-2.4, stable-2.5, stable-2.6
branches.

Fix: get the stream_id when generating live beacons
When we send an empty index (beacon), we need to extract the stream_id
to avoid stalling the client on inactive streams on startup.
Since the live clients need to know this feature is implemented, we had
to bump the lttng-live protocol version.
This fix should be backported to stable-2.4 as well.

Fix: use biggest subbuffer size for snapshot max-size
Instead of using the output max size divided by the total amount of
streams in the session, we find the largest subbuffer in the session's
channels. Using that value, we multiply it by the total amount of
streams which gives us the lower limit of the snapshot size. That is
enough to make sure that we can take the snapshot or not.
Once done, the max stream size possible used for the snapshot record is
the largest subbuffer size in the session. This is to make sure that
every channel can extract the same amount of data which ensure fairness
between each channel in the session.
