MediaEventLooper: Remove soft real time lateness bounding

* The media_kit isn't an hard real time beast. Bounding lateness
looked like the perfect way to enable reasonable soft real time
performance and thus limiting port writes and reads between producers
and consumers. It seems to don't work very well so I just remove it.
* The result of the recent code simplification makes it equal to my
first version, before any discussion on it happened.
* Thanks to AlienSoldier for testing such issues.
* Fixes #13069.

BMediaEventLooper: Return to simple lateness computation

* Lateness seems generally useless. No way to get something useful
experimentally. The commit noise however was useful, the port wait is
behaving more in accordance with the lateness calculus.

and safer eventually.

BMediaEventLooper: Handle events in past differently

* When the loop didn't handle an event in performance time, we will
attempt at reading the port only if there are messages using a null
timeout.

MediaEventLooper: Calculate lateness from the nearest value

* When the event is late there are two major situations, the first
is when the enqueue time is in past compared to the performance time.
The second happen when the performance time is in past compared to the
enqueue time. The purpose of this change is to calculate the lateness
considering always the nearest of the two values. This way the exceding
latency is trimmed out from the calculus depending on what the actual
source of delay is.
* There is a lot more that could be done by looking at the previous
lateness value.

BMediaEventLooper: Use enqueue_time in a different shape

* This is the only solution that allowed to use the best
of both ways to do this calculus. I've also tested it
with a modified sound player that snoozed every time
the buffer should be handled, and found that neither
of the lateness calculus I tested (including enqueue_time)
really solve all problems. That's why I've tried to find
an average solution. There's still room for improvements
eventually.

BMediaEventLooper: Make lateness calculus in real time

* After having this patch applied locally for some time,
I'm going to be sure that we have to deal only with real_time values.
* Since RealTime() is just a system_time() wrapper, the code
will be slightly improved in performances too.
* Additionally it performs very well when the thread is
externally stopped (such as debugging it), so that the audio
recover almost immediately.

BMediaEventLooper: Finally fix some lateness problems

* For the moment i still remain with the classic lateness calculus.
My code wasn't perfect, but this commit fix the remaining
problems from my perspective.
* The first reason is that if we have a patologic latency
such as adding for experimental reasons a snooze() before a SendBuffer or
in the BufferReceived callback, we still can't do anything about it.
If we use enqueue_time and don't send a LateProducer notice, this latency
will never be detected by the API client. We can't do anything about it,
and it's even better that systems with such problems are recognized as
soon as possible IMO.
* The second reason is that the lateness calculus described in the BeBook
is done this way because the media_kit want us to adjust our timing in both
early and late situations.
* Realtime expect that things are always delivered under a certain time
limit, if the software at the bottom doesn't meet with this requirement,
it's just not realtime and things can't work in realtime.
* enqueue_time has nothing to do with the performance_time. But we can
still add this to the media_timed_event struct so that applications can
make use of it.
* Lateness was probably not used a lot in BeOS programs as it looks like
a relatively new feature but i have the concern to complete our API
implementation to be close to what i see was reasonably the designers aim.

BMediaEventLooper::ControlLoop: Review style/logic, no functional change

* The code is just reversed to be better organized.
* Since the first event will be handled after a port write, at thread
spawn we just wait with infinite timeout for new messages.
* Remove goto which then become a continue.
* This permitted to remove the double waitUntil assignment which
was in different braces.
* lateness var become tempLateness, so it become more obvious than
before that it's a cached value and we are doing this to avoid
double calculus.

BMediaEventLooper: Rewrite ControlLoop()

* The first problem was the O(n^2) complexity of the algorithm, it's
now linear and try to act in a circular way by dispatching
events and reading the port in a balanced way. This exclude
a certain degree of possible deadlocks.
* Add detection and escape when the system try to kill the
thread. This solve some blocking issues on exit et similia
that i had with libjackcompat.
* The algorithm choose soon which event to focus on.
* Lateness is calculated just before the event is dispatched
as it is the more appropriate place, otherwise we would be
calculating something imprecise/guessed.
* Remove timed_event_queue::queued_time. It's more precise to
just use the RealTime() before to Dispatch the event.
* It should solve the BSoundPlayer lateness problems.
* With those improvements the media_kit is not going to lock
completely under stress conditions, instead it try to work
in a best effort shape.
* There's still room for improvements, for example i'm considering some
strategies in lateness situations such as update scheduling latency,
try to decrease waiting time and detect when we are too early on
the other hand to recover when the load go down.
* Thanks to Julian Harnath for sharing his WIP patch which helped
with some controls such as avoiding negative lateness.
* Comments are welcome!

Additional changes:

needed by packagefs.
* BuildFeatures: Add a build feature "gcc2" to allow for easier checks.
* Referenceable.cpp: Include <OS.h> instead of <debugger.h>. The latter
is not needed and prevents building for the build platform.
* zlib/zutil.h: Fix gcc 2 build. We really should use the external
package instead.
