Fix: enable-consumer for all domains missing dir
So the fix here is to enable consumer for all domains if no domain is
given to the command line. This way, the session daemon can handle
correctly the trace directory path for the right domain.
Note that there is *no* switch for all domains (-a, --all) so omitting
the domain (-u or -k) automatically creates a UST and kernel session, if
none, and set the consumer for both of them. If one fails, the command
is stopped. All in all, to be sure, use a domain with the command ;).

lttng.h API update: set filter becomes enable event with filter
The lttng_set_event_filter() is changed to
lttng_enable_event_with_filter() taking the same arguments. The lttng UI
now only uses this call. Note that the original lttng_enable_event() is
still available but will set the filter to NULL.
This is done since now UST allows to enable the same event with
different filters or/and loglevels. So, the events are still hashed by
name but matched by the name/filter/loglevel triplet. In order to add an
event to the hash table, those three attributes are needed at the
creation time thus adding this API call which takes them all at once.
There is some fixes in the match functions and filter setting from the
previous commit that were needed to make the overlap.sh tests works.
The loglevel_match function is removed because it is now only done in
the hash table match function which will eventually get merged making a
single loglevel match call site hence this function becomes useless.
Furthermore, the filter.c/.h are no longer required since the filter is
now added at event creation and CAN NOT be set after.

Furthermore, when adding libraries to noinst_LTLIBRARIES, libtool will
only build these as static libraries (see [1] for a workaround). This is
fine for most use cases, but for the health tests, we _must_ have shared
libraries (the nature of the tests require LD_PRELOAD), hence we force
the build of a shared object.
Forcing shared object has the unfortunate side-effect of breaking builds
where configure was invoked with "--disable-shared" flag. Instead of
failing badly, detect this flag and skip the health tests altogether.

Fix: Wrong poll events on UST application socket
The thread manage apps was adding UST sockets to the poll set with the
POLLIN event registered. However, the thread was not handling this event

This has been observed with the bug386 when an application is stopped
and a lttng command is sent.
https://bugs.lttng.org/issues/386
Furthermore, a time window between the send and the reply recv of an UST
command was making the app manager loop actively because of a POLLIN
event on the socket caused by the reply from the application which is
finally handled a bit after by the client thread. This was not that
problematic but lead to a lot of repeated debug message and CPU time
lost.

Fix: Bad return error code handling
Two things here. First, if the tracer dies before we have time to create
the session on it, the returned value (-1) was not handled creating a
segfault on the following loop.
Second, we no longer assert on the application PID hash table delete
return value since we use add_replace on app. registration creating a
possible key reuse for a different node.

Fix: consumer output memory leak on creation
The sockets hash table was allocated two times hence losing the first
reference at the second allocation.
Furthermore, when a kernel/ust session is created, a default consumer is
allocated but was lost short after that when the tracing session current
consumer was copied and the pointer was overwritten.
Note that this fixes the memory leak but there is a code logic that
seems wrong when it comes to handle the consumer object trace path and
subdir during the session creation. A comment has been added and it
should be fixed.

Fix: Delete stream on write error in consumer
Whenever a write() error occured, both on network or local trace file,
the consumer thread just died considering the error a fatal one.
This commit fixes that by simply deleting the stream, removing it from
the poll set of the thread and freeing it.
Furthermore, on a write() error, a SIGPIPE is usually raised if the FD
is invalid. The consumer is catching this signal but was initiating a
should exit action thus ultimately cleaning all threads. We now still
catch SIGPIPE but don't set the should quit flag so normal cleanup can
be done by the threads.

Tests: Add a test for valid filters
This test validate that for a given filter the expected trace output is
conform to the expected filter behavior.
This test rely on the babelstats utility. With the help of this script,
we can verify that the expected minimum and maximum values on fields of
interest are within the expected ranges.
For example, given 100 iterations on a tracepoint with the field
'intfield', with values starting from 0 and incrementing on each
iteration, and the filter expression 'intfield < 4', we would expect
that the min-max range lie within [0,3].
Thus, if the babelstat computed range does not match the expected range,
this could potentially indicate failure in the filtering mechanism.
