A warning is fine since the user has no control on

MI wise the command is not a success since nothing was

Fix: Set loopback adress in set_ip_addr if gethostbyname2 fails
Some systems may not have "localhost" defined in accordance with IETF
RFC 6761. According to this RFC, applications may recognize
"localhost" names as special and resolve to the appropriate loopback
address.
We choose to use the system name resolution API first to honor its
network configuration. If this fails, we resolve to the appropriate
loopback address. This is done to accomodate systems which may want to
start tracing before their network configured.

Fix: load event state (enabled/disabled) correctly
This bug fix is a workaround due to limitations of lttng_disable_event_ext
regarding the disabling of events with similar name but different
characteristics. Although lttng_disable_event_ext provides support for
disabling by name and filter string it does not support exclusion.
The loading of events is cut in 3 phases.
1 - Create all events regardless of their state.
2 - Disable all events.
3 - Enable only the events with the 'enabled' state.

Fix: UST should not generate packet at destroy after stop
In the following scenario:
- create, enable events (ust),
- start
- ...
- stop (await for data_pending to complete)
- destroy
- rm the trace directory
We would expect that the "rm" operation would not conflict with the
consumer daemon trying to output data into the trace files, since the
"stop" operation ensured that there was no data_pending.
However, the "destroy" operation currently generates an extra packet
after the data_pending check (the "on_stream_hangup"). This causes the
consumer daemon to try to perform trace file rotation concurrently with
the trace directory removal in the scenario above, which triggers
errors. The main reason why this empty packet is generated by "destroy"
is to deal with trace start/stop scenario which would otherwise generate
a completely empty stream.
Therefore, introduce the concept of a "quiescent stream". It is
initialized at false on stream creation (first packet is empty). When
tracing is started, it is set to false (for cases of start/stop/start).
When tracing is stopped, if the stream is not quiescent, perform a
"final" flush (which will generate an empty packet if the current packet
was empty), and set quiescent to true. On "destroy" stream and on
application hangup: if the stream is not quiescent, perform a "final"
flush, and set the quiescent state to true.

Snapshot warning if there are no events in one of the domains
Remove the "no data" check from the UST snapshot code since
1) It would report that no data was recorded in the snapshot even
if the kernel tracer had recorded events,
2) The kernel consumer does not seem to report such a condition,
making it hard to perform the check without modifying the
consumer.
The consumer interfaces could be modified to reliably provide
this information in the future.
However, this warning is not provided in the other tracing
modes, making its usefulness questionable. An empty snapshot is
still a valid trace and users should not always expect a trace
to contain events. Moreover, "warning" that no data was produced
implies an error may have occured and is probably as confusing
as opening an empty trace to the average user.

tests/unit: fix object files' location
Referring to *.o files under a .libs/ directory is not recommended
because this belongs to libtool's innards.
Indeed, libtool decides to place the *.o files in an
implementation-specific location:
- PIC *.o files go into a .libs/ directory;
- non-PIC *.o files are generated along side to their corresponding
source files.
Using PIC objects to build executable is legit, thought it may
introduce some minor overhead at runtime.
However, hard-coding these PIC object files in the Makefile.am to build
executables breaks the build in case of static only build.
In this case, no PIC object files is generated, so the linker will not
found some of the needed objects files.
Changing these dependencies' path fixes the static build, keeping the
shared one ok, though the non-PIC object files are now always built.
Fixes #983.

Therefore, we can destroy all indexes for which we have received only

Fix: LPOLLHUP and LPOLLERR when there is still data in pipe/socket
The event mask returned by poll/epoll is a bitwise mask made of all the
events observed. On bidirectional sockets, there are cases where
combinations of LPOLLHUP/LPOLLERR and LPOLLIN/LPOLLPRI can be raised at
the same time.
Currently the overall behavior in sessiond, consumerd and relayd is to
handle LPOLLHUP or LPOLLERR immediately, whether or not there is still
data to read in the socket. Unfortunately, this behavior may discard the
last information made available on the pipe or socket.
Audit all uses of LPOLLHUP and LPOLLERR on sockets on which we expect
data to ensure that we deal with LPOLLIN or LPOLLPRI, and catch the
hangup when read or recvmsg returns 0. Keep the LPOLLHUP and LPOLLERR
handling, but only when LPOLLIN is not raised, just in case some
unforeseen error happens when sending the reply.
This is one correct case where we can handle LPOLLHUP and LPOLLERR
directly without caring about LPOLLIN: sockets where we are expected to
write and then read the reply (e.g. command sockets). It is then OK
for a dedicated thread to watch for LPOLLHUP and LPOLLERR.

Fix: don't print the default channel name when enabling agent events
Enabling an event in the python domain erroneously reported the
channel as being the default `channel0`. Instead, don't report the
channel name when enabling an event in an agent domain.

Fix: fail gracefully on --exclude on unsupported domains
Trying to use event name exclusions on unsupported domains other than
kernel (i.e. log4j, jul, and python) would hang the client. Instead,
report the error appropriately.
