ltt-sessiond teardown cleanup
ltt-sessiond now kills (SIGTERM) the kconsumerd before exiting, so the
LTTng module unload succeeds. Previously, the kconsumerd was still
holding a reference on ltt-relay.ko -- it was only being released after
ltt-sessiond closed its communication socket with kconsumerd.
Now, all the teardown actually wakes each thread, getting them to
return, and main() joins each of them before calling cleanup().
Previously, we had no guarantee that threads would not run concurrently
with cleanup() executed from the signal handler.
It would still be good to audit _each_ read call so we ensure that they
are performed on O_NONBLOCK fcntl fds (as we did in the kconsumerd), so
all the blocking is done in a poll() call, which can be woken up by the
sessiond termination file descriptor too (from the signal handler).
Failure to respect this could lead to races where sessiond blocks on a
file descriptor and never really honour the signal for a thread, thus
leading to blocking of the main() thread on a join.

New public API for lttng control
Introduce the lttng domain that is used to identify the tracer.
Remove all 'kernel' from the functions name and now take the domain
struct as first parameter.
Add channel feature is removed and merged with enable-channel.
Move kernel specific data structure from lttng.h to lttng-kernel.h which
is copied from the LTTng kernel modules ABI. Genereic structures are
used to create a generic view of lttng event and attributes (agnostif of
the Kernel and user-space).
Default channel is NOT created unless it is needed.
A lot of comments has been added to lttng.h
Fix a bug in the liblttngctl. A return value was not set correctly.

Remove connect/disconnect sessiond from lttng API
Those actions are made internally when a command to the session daemon
is done so no need for them to be public.
Move code around to make things clearer and fit static declaration.

Remove libustctl and libustcomm
Those libs are part of the soon to be deprecated user-space tracer. The
code is removed but not the directories and Makefile.am.
lttng-tools will only support UST 2.0 which is not yet released at this
point in time. Thus, this is not useful anymore and will be readded
later on to support the new user-space tracer.
Also disable a small portion of code in the session daemon that uses
libustctl. This code however remains relevant for future UST
integration.

tracing guide since ust 2.0 is not released at this point.
