preserve the dirty flag of the mapping without having to potentially move the
page to the modified queue. This lifts the (ignored) requirement that the
pages to be unmapped must not be busy.

It still miss at least some checks about packet sizes and frame termination and probably some more error handling.

* Use atomic_{and,or}() instead of atomic_set(), as there are no built-ins
for the latter.

B_USE_BUILTIN_ATOMIC_FUNCTIONS is defined most atomic_*() functions are
redefined as macros using the built-ins directly.
* Enabled that feature for the x86 build. Might work on other platforms as
well, but that needs to be tested.
No significant speedup for the -j8 Haiku image build.

* Fix the boot net stack's IPService to base the calculation payload size
on the IP-indicated packet size instead of the Ethernet payload.
Thanks a lot! Fixes ticket #5234.

This makes appending the pages to the active queue more efficient and we
don't need the vm_page::is_cleared bit anymore.

short and quite hot, so mutexes just cause more overhead due to frequent
rescheduling than waiting for the spinlocks does. The free and clear queues
are additionally protected by a R/W lock, which is mostly read-locked, save
for rare cases like allocating page runs.
The total -j8 Haiku image build speedup is marginal. The kernel time drops
about 8%, though.

that causes a locking order reversal (condition variable lock <-> system
profiler lock) and thus a potential deadlock. Instead we use the thread
blocking API directly. Fixes#5229.

I had to uptade the catkeys as Travis tool has trouble keeping up with changes in the repository (most importantly, cpufrequency fixes and mail sentance casing). I hope nothing was lost in the process.
Travis, if you read this, I had to load the catkey files in vim and save them back to get them linked correctly by the buildtools. I suspect some line ending problem or something alike. Also, your fingerprint computation seemed wrong in most cases.

- Haiku doesn't like the ethernet maximal frame size to be set to 0. This drops the CPU usage and some calls to read/write are now occuring.

which virtual pages are mapped to the page.
