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.

Cleanup error.h __lttng_print() used for message printing
The loglevels have never really been a mask, and it is useless to try to
use them as masks, because the compiler statically knows the value of
the loglevel requested, and can therefore optimise away all the logic.
This takes care of Coverity warning about mixed bitwise and boolean
logic, which was technically correct, but more complex than needed.

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.

This should not really be an issue since
1) options that use the "arg" parameter will not be set by popt if one
is not provided,
2) the configuration file parser will never invoke set_option with
a NULL argument; if no "value" is provided in the file, an empty
string is passed.
The second point is the reason for the "arg && arg[0] == '\0'" check;
we already know that the argument is invalid since an empty string
is never a valid argument for the supported options.
Nonetheless, it makes sense for Coverity to flag this and moving
the check to individual cases, although very verbose, is clear.

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.
Fix tested on git master and v2.6 with no change needed.

configure.ac: fix static build
For static build, some extra LDFLAGS may be needed.
Using PKG_CHECK_MODULES instead of AC_CHECK_LIB for librairy detection
allows to get all these flags. Then, the LIBS variable can be extended
with everything that is needed.
So, use PKG_CHECK_MODULES for popt and uuid detection; which both depend
on libintl.
This changes fixes build failures triggered with Buildroot, e.g.:

Fix: close indexes when rotating the trace files in splice mode
The consumer needs to close the old index file when doing a file
rotation before opening a new one.
The relay does not have this problem (handled with refcounts).

Fix: Check for NULL hash tables on relay daemon teardown
The relay daemon will log any "leaked" object on exit. However,
some errors encountered early-on during the daemon's
initialization may result in the teardown being executed with
uninitialized hash tables.
