Make the consumer sends a ACK after each command
This is needed to avoid buffer bloating when throttling communication
between the consumer and the relayd. Considering a very low bandwith
limit between the relayd and consumerd, the session daemon would send a
high debit of commands to the consumer without ever
emptying the unix socket queue, which makes the UNIX socket reach buffer
full conditions, which is prone to trigger corner-cases behaviors in
blocking send/recv with MSG_WAITALL, which is likely the cause of hang
experienced when limiting relayd bandwidth.
Adding an ACK to each command makes sure that we acknowledge the session
daemon that we, the consumer, have emptied the unix socket buffer.
NOTE: In consumer_add_relayd_socket(), there might be a problem with the
error path and message status to the sessiond. A subsequent patch might
fix a possible issue but for now it is not at all critical since any
critical error on the consumer side will notify the sessiond through the

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.

Fix: Enable event after start command
Refer to the bug tracker for more information on this bug. In a
nutshell, it was not possible to enable channel/event after a start
command has been issued (for both kernel and UST).
Note that it is still NOT possible to enable a channel after a start but
the use case here was the following:
$ lttng create
$ lttng start
$ lttng enable-event -a -u (or -k)
The first starts does NOT create a kernel or UST session so the
following enable event creates the session for the given domain but
failed to start the session after.

Fix: Teardown of thread_manage_clients on failure of listen/create_poll

Fix: Do not install health tests helper libraries
The libraries libhealthexit and libhealthstall should not be installed
on the user system. They are only useful for the health check tests.
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
which could ultimately cause an infinite loop if the application sends
data.
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.
This application thread is *only* handling error event usually triggered
by a close() on the UST socket thus OK to *not* wait for POLLIN/POLLOUT
event.
