* simple_smp scheduler: Rewrote the interesting part of
enqueue_in_run_queue(). It always selects a target CPU for the inserted
thread, now. If no CPU is idle, the CPU running the thread with the lowest
priority is chosen. If the thread running on the target CPU has a lower
priority than the inserted one, it will be asked to reschedule. If that's
the current CPU, we'll return the correct value (wasn't done before at
all).
These changes help reducing latencies. On my machine in an idle system
playing music DebugAnalyzer shows maximum latencies of about 1 us. I still
find that a bit much, but it's several orders of magnitude better than
before. The -j8 Haiku image build time dropped about 10%.

returning B_INVOKE_SCHEDULER from the interrupt handler, causing
latencies up to a full quantum for the multi audio output thread. This
change improves audio clicks quite a bit on my machine. Though they still
happen from time to time and particulary on FS activity.
* Automatic whitespace cleanup.

setting the input frequency, but I'm too lazy and not interested in the feature
to actually implement it.
For some reason the setting is not persistent. But the other parameters don't
seem to be persistent either, so this is apparently a general problem.

FreeBSD 8 (r199625) and thus adding the FreeBSD license header.
* Implementing the glue code to make the wavelanwifi driver linking.

Both are compiling, but not linking yet. Only for compilation of pci support
has been taken care of, as neither ISA nor PCMCIA are usable within Haiku
anyway.
* Enhancing the FreeBSD compat layer so that the above drivers are compiling.

The internal_intr structure needed to be adapted accordingly, otherwise it
would not compile anymore.
This definition is needed by the aironet (if_an.c) driver I'm currently
porting.
* Extending FreeBSD compat layer a bit in preparation of porting the remaining
wlan drivers.

I'm afraid there is nothing left of stippi's earlier solution. This fixes
bug #5097.
* The alignment as specified in the BToolTip is now respected.

implemented by means of an additional member in cpu_ent.
* Removed thread::keep_scheduled and the related functions. The feature
wasn't used yet and wouldn't have worked as implemented anyway.
* Resurrected an older, SMP aware version of our simple scheduler and made it
the default instead of the affine scheduler. The latter is in no state to
be used yet. It causes enormous latencies (I've seen up to 0.1s) even when
six or seven CPUs were idle at the same time, totally killing parallelism.
That's also the reason why a -j8 build was slower than a -j2. This is no
longer the case. On my machine the -j2 build takes about 10% less time now
and the -j8 build saves another 20%. The latter is not particularly
impressive (compared with Linux), but that seems to be due to lock
contention.

timer_interrupt() return B_INVOKE_SCHEDULER. The scheduler itself uses a
timer hook and relies on scheduler_reschedule() to be called. Will make this
even more reliable in the next commit.
This might fix#3535.

* Added a special SIOCEND define to Haiku's sockio.h, so that drivers can define
private ioctls as can be seen in src/add-ons/kernel/drivers/network/wlan/atheros/dev/ath/if_athioctl.h.
* Modified ioccom.h of the FreeBSD compat layer, to make use of the special
SIOCEND define.

accessible from the outside.
* Instead, request_data now retrieves/releases a reply port on its own.
* There were some more places that still used write_port()/read_port() instead
of QueryServer().

usual structures.
* Also, they now use the QueryServer()/SendToServer() functions instead of
duplicating them.

* Fixed at least two reference counting problems, but nodes from killed teams
still remain alive (will look into this at a later point).
* GetLiveNodes() is now using transfer_area() as well.
* Made all sizes in the SendTo*() and Query*() functions size_t.
* Replaced reinterpret_casts with static_casts when casting void pointers.
* Ordered the request/reply structures by target.
* Tried to consolidate the use of add_on vs. addon.
* More cleanup.

pointers to all events now. This allows for backward iteration.
* Model::ThreadWaitObjectGroup: Added a few convenience getters.
* Added functions thread_state_name() and wait_object_type_name() to translate
a ThreadState respectively a wait object type into a readable string.

sys/condvar.h and as such the kernel_c++_structs.h file in their souces.
As Ingo pointed out when introducing the "C++ structs in C only code" feature,
this dependency needs to be put on every target that includes
kernel_c++_structs.h directly and indirectly.
