* SetParameterValue(): Don't do anything, if the new output frequency value
is the same as before. This avoids hickups when switching between the pages
in the Media preflet.
* _FillNextBuffer(): Compare BBuffer and stream buffer size. They might
differ directly after setting another output frequency, which could cause
a crash.

as soon as a second thread got into the game: if a thread was notified that
a message is ready, another thread could call read_port() and steal it before
the previous thread could claim it. The "Extensions" menu still doesn't seem
to work, but I would guess that is unrelated.
* The threads of the test app never exited, as read_port() returns the number
of bytes it read, not just a status.

- Round the DMA position for the buffer cycle computation. Apparently some
chipsets trigger the interrupt before the position has been updated.
- Don't just assume that stream->buffer_length frames have been processed
at that time. Use the exact stream position at that time. This makes the
performance time computation more precise and immune to the interrupt
being delayed.
* Init hda_stream::frames_count.
Audio skips on I/O seem to be gone for me, now. Not obviously motivated skips
still happen.

This saves ~0.5s of boot time here, but I suspect it might be better for CD.
Enabled loadSymbols in kernel settings so the behavior should be the same as before this change.

descriptor n link position in buffer) registers. They contain "the number
of bytes that have been received off the link", which is not to be confused
with the number of bytes that have been transferred by the DMA engine.
The interrupt is triggered when the last byte of the buffer has been fetched
by the DMA engine, at which point the stream's LPIB is still somewhere in
the last buffer. So the interrupt handler could compute the wrong buffer
index, which would lead to the multi audio add-on filling the wrong
(currently being transferred) buffer, resulting in noisy sound. Now we use
the DMA position. Should fix#4072.
* Also removed the not (always) working hack-around for the "wrong" buffer
positions in the interrupt handler.

* There is firmware needed, which can be distributed with Haiku:
a) Get the firmware from www.ralinktech.com -> Software -> Linux
-> Firmware RT2501(RT2561/RT2661)
b) Extract the three binaries to /system/data/firmware/ralinkwifi/
c) Rename them by removing the '.bin' ending and append fw instead
(e.g.: rt2561.bin -> rt2561fw)

and not malo8335 as I stated in commit r34661.

* This driver requires a firmware, which is not publicly available, and
therefor cannot distributed with Haiku. To retrieve and install the firmware
nonetheless following steps are required:
a) Download the firmware from http://www.nazgul.ch/malo/malo-firmware-1.4.tgz
b) Copy the included firmware files malo8335-h and malo8335-m to /system/data/firmware/malo8335/

currently only shown in the monitor tool tip, that is now feels a bit crowded,
so a better solution would be nice. I'm hesitant to give it a more prominent
position, though, unless one has proof-read what the accelerants actually
return here.
* Added missing space between the serial number of the monitor and the date it
has been produced.
* Renamed fTempScreenMode to fUndoScreenMode, as it's only used to deliver that
functionality.

- enqueue_in_run_queue() no longer returns whether rescheduling is supposed
to happen. Instead is sets cpu_ent::invoke_scheduler on the current CPU.
- reschedule() does now handle cpu_ent::invoke_scheduler_if_idle(). No need
to let all callers do that.
* thread_unblock[_locked]() no longer return whether rescheduling is supposed
to happen.
* Got rid of the B_INVOKE_SCHEDULER handling. The interrupt hooks really
can't know, when it makes sense to reschedule or not.
* Introduced scheduler_reschedule_if_necessary[_locked]() functions for
checking+invoking the scheduler.
* Some semaphore functions (e.g. delete_sem()) invoke the scheduler now, if
they wake up anything with greater priority.
I've also tried to add scheduler invocations in the condition variable and
mutex/rw_lock code, but that actually has a negative impact on performance,
probably because it causes too much ping-ponging between threads when
multiple locking primitives are involved.

IORequest::Wait(). Wait() immediately returned when IsFinished() returned
true, but this is the case as soon as the last IOOperation has finished. The
I/O scheduler is not done with the request at this point, though, since it
will still be sitting in at least one of three doubly linked lists. Since the
usual procedure to issue synchronous I/O requests is to create an IORequest
on the stack, pass it to the I/O scheduler, and Wait() on it, Wait()
returning early might cause the IORequest object to be destroyed while it is
still in use, leading to invalid memory access in the I/O scheduler,
corruption of its list structures, as well as later corruption of the issuing
thread's stack.
Related tickets:
* #4431: The request issuing thread returned and already deleted the area the
request was writing to before NotifyFinished() was called.
* #3048, #4883: Caused by the on stack IORequest being overwritten with other
data while being handled by the I/O scheduler thread.
* #4517: Hard to say, but I've seen a such a problem too, after a thread
scheduling related change. An explanation would be a list structure
corruption in the I/O scheduler causing an infinite loop with disabled
interrupts.
* #2845, #3428, #3429: The block notifier/writer is I/O heavy and as such
quite likely to run into the stack corruption issue.

* Moved the CPU selection conde into a separate function.
* Re-added the support for disabling CPUs, which I accidentally removed.
* Got rid of idle CPU tracking. We don't need it anymore -- we iterate
through all CPUs and check the priority of the running thread.
* Added a kind of round-robin component to the CPU selection loop, so that
we pick CPUs more evenly. And indeed, the ProcessController display is
less skewed, now. There doesn't seem to be a measurable performance gain,
though.
