The subdir in the consumer_output structure is supposed to be the

Fix: path of snapshots with a relay and default URI
When recording a snapshot to a relay without custom URI (ex:
net://localhost vs net://localhost/custom), the snapshots end up being
stored in ~/lttng-traces/<hostname>/snapshot-XXX instead of being inside
the <session-name> folder like on local snapshots. We would expect the
path to be: ~/lttng-traces/<hostname>/<session-name>/snapshot-XXX
So there is a discrepancy between the local and remote behaviour. This
behaviour has been there since at least v2.6, maybe earlier.
Moreover, there is nothing that informs the user about the default
snapshot name, so it is not possible to know where a snapshot has been
stored.
After parsing the URI provided by the user, we now check if a custom
name was provided or copy the session name there. This is the same
operation performed in _lttng_create_session_ext.

Fix: ambiguous ownership of kernel context by multiple channels
A kernel context, when added to multiple channels, must be copied
before being added to individual channels. The current code
adds the same ltt_kernel_context structure to multiple kernel
channels which introduces a conceptual ambiguity in the ownership
of the context object.
Concretely, creating multiple kernel channels and adding a context
to all of them (by not specifying a channel name) causes the context
to be added to each channels' list of contexts, overwritting the
context's list node, and causing the channel context lists to become
corrupted. This results in crashes being observed during the
destruction of the session.

Fix: doc/man: use a single XSL file and match local names
Matching the local name instead of the full name, that is:
*[local-name() = 'co']
instead of just `co` matches both the non-namespaced element and
the DocBook-namespaced element whether we're using the DocBook 4.5 or
DocBook 5.0 stylesheets.
