Fix: use after free of a relayd stream
A race could occur with a stream destruction and a control connection
being destroyed emptying its recv_list. A freed stream could still be in
the list thus having a use after free during the connection destroy.
That was triggering undefined behavior from infinite looping to
segmentation faults.
We've observed this issue on high load stress test. A relayd received
all the stream but NOT the streams sent command which empty the list.
This can happen if a start tracing never occured or failed on the
application side thus the close stream command is sent to the relayd
freeing the stream before it is removed from that list.

Fix: don't print stream name in error message
The stream received, in per UID, is actually a temporary stream object
that only contains the UST object data which is the relevant part for
UST to use.
Thus on error the name was random data thus print the valid handle
descriptor instead of invalid data.

Fix: take session list lock when listing tp
This is important since the list tracepoints command access the
application socket to ask the application for its TPs. The session list
lock protects the ordering of message for those sockets.
This was triggering out of order message between the session daemon and
an application thus triggering undefined behavior.

Fix: add consumer wake up pipe to avoid race
UST application will notify the wait_fd pipe for every subbuffer that it
writes and ready to be consumed. However, on *high* load systems, this
1:1 property can fail if the pipe gets filled up. For performance
reason, UST will ignore this error and continue since it can't wait for
the pipe to clear up.
This triggers a race condition where we have *one* wake up on the UST
pipe for potentially multiple subbuffers. A data pending command will
wait forever on streams that still has data but the data thread could'nt
consumed them because of this 1:n possible race. Using the stop command
without waiting would mean a memory/fd leak of the stream.
Thus, we add a consumer wake up pipe here that notifies the data thread
if there is still data to be read after a successful read subbuffer
call. With this, we end up handling the residual buffers if any since
the data thread is always notified when there is still data to be read.

Fix: forbid session name creation if contains /
This adds a validation function for session name which for now denies
any session name containing '/'.
This is in response of bug #721 that actually uses a path as a session
name such as "test/../session1" which would then be concatenated to the
session path adding a relative path to it making this a serious security
issue.
Because of this issue, this is backported from master up to stable-2.3.

Fix: report error if consumer can't be spawned
On error of the UST consumer execl(), we now exit the forked process
like the kernel does.
Furthermore, fix an error handling value when timing out when waiting
for the consumer to bootstrap thus returning an error to the client and
not continuing with the command thinking that the consumer was actually
spawned.
So, the expected behavior is to wait for the pthread condition and if a
timeout is seen, the client is informed thus making the client command
hang for the default timeout value of 30 seconds.

Fix: kernel channel destroy on consumer if sent
An enable-channel immediately followed by a destroy session triggered an
assert on the consumer followed by the shutdown of the consumer thread
for the kernel.
This fix make sure we don't ask the consumer to destroy a channel if not
previously sent to it and handle not found channel on destroy.

- The LTTNG_CONSUMER_STOP command is not used by sessiond anymore, so
deprecate it,
- Ensure that the normal teardown (with signal handler) does not trigger

"should exit" with different lttng_consumer_poll_socket() return values.
