make check: add warning when LTTng processes are running
This patch adds a warning when running LTTng/test processes are
detected at the beginning of make check. It offers a convenient
way to kill them and warns the user that some tests could fail
if the processes are kept alive.
The check can be disabled by setting
$LTTNG_TOOLS_TESTS_DISABLE_WARN_LTTNG_PROCESSES to 1

lttng enable-event -u -a --exclude hello,a,b,c,d

Fix: Remove dependency on glibc 2.12 caused by pthread_setname_np
prctl() can be used to set the same attribute set by
pthread_setname_np, but doesn't introduce a dependency on a newer
glibc. Using prctl(PR_SET_NAME) introduces a soft dependency on
Linux 2.6.9. However, the worker won't fail to launch if the call
fails as it is set out of convenience (debugger output).

Fix: Log and ignore SIGINT and SIGTERM in run_as worker
The run_as worker is in the same process group as its parent and
will receive both SIGINT and SIGTERM. However, we want to give
the worker a chance to tear itself down gracefully when its
parent closes the command socket.
The run_as worker will now ignore these signals (although it will
log them) and wait for the parent to induce the teardown.

Fix: disable kernel event based on name and event type
The -a argument is interpreted as a zero-length event name
instead of '*' which is actually a valid wildcard event
name by itself. This simplifies how a disable command is
handled by the session daemon.
The event type can now be passed as argument and is a
new criteria while disabling kernel events. The default
is to disable for all event types.
UST and agent domain do not yet support disabling by event
type.
e.g:
# Only disable kernel event of type tracepoint.
lttng disable -a -k --tracepoint
# Only disable the event with name '*' and type syscall.
lttng disable -k '*' --syscall
# Disable all kernel event of all type.
lttng disable -a -k

Fix: Break out of loop when searching for a domain's agent
The list command never check if a domain's agent has been found
and lists the events of every agent.
This has two direct effects:
1) Memory leak of all agents' event descriptions, except the last
2) The session daemon lists the wrong agent's events
This fix check the agent's domain and breaks out of the loop once
one is found.

Fix: tests: skip UST perf tests if not root
Some distributions like Debian (e.g. Debian kernel 4.1.0-2-amd64) have
some grsecurity options enabled, such as CONFIG_GRKERNSEC_PERF_HARDEN.
Unfortunately, this option makes it impossible to use the SW page-fault
perf event as a normal user. It only leaves some HW events. However, we
can only use SW events within virtual machines.
Therefore, only run this test as root for now until we find a better
approach.
