Modify default kernel channel size/number
Too small kernel channels (4kB) leads to unwelcome delay at trace
indexing and adds buffer switch overhead. Use a default closer to the
0.x LTTng for buffer size:
256kB subbuffer
4 subbuffers/buffer
for 1MB per channel per CPU in normal tracing mode, and 1MB + 256kB per
channel per CPU in overwrite mode.
We currently plan to still use 4kB * 8 sub-buffers for UST because we
allocate these buffers per process, which makes memory consumption more
of a concern.
The metadata channel is kept small (4kB), but we keep a number of
subbuffer of 8 for now, as the behavior between "start" and spawning the
consumer is in the wrong order: we will need to spawn the consumer
before start is performed, because "start" returns blocks for 10 seconds
and returns an error if the buffers are too small to write metadata (and
they are not consumed).
Also fix a memory leak in init_default_channel.
process_client_msg() now uses a check / alloc / failure for channel
lookup rather than an endless retry, which could have led to denial of
service in case of internal error.

Rename and export lib kernel consumer

publicly having the public header "lttng/lttng-kconsumerd.h".
To link with this library, use -llttngkconsumerd.
Every public functions now begins with the "lttng_" prefix to fit the

Comments are changed also to fit 80 lines standard and the rest of the
git tree comments.
This complete renaming was motivated by the new tool made by Julien
Desfossez called 'lttngtop' which uses the kernel consumer library to

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.
