* Added VMCache::MovePage() and MoveAllPages() to move pages between caches.
* VMAnonymousCache:
- _MergeSwapPages(): Avoid doing anything, if neither cache has swapped out
pages.
- _MergeSwapPages() does now also remove source cache pages that are
shadowed by consumer swap pages. This allows us to call _MergeSwapPages()
before _MergePagesSmallerSource(), save the swap page shadowing check
there and get rid of the vm_page::merge_swap flag. This is an
optimization based on the assumption that usually none or only few pages
are swapped out, so we save a lot of checks.
- Implemented _MergePagesSmallerConsumer() as an alternative to
_MergePagesSmallerSource(). The former is used when the source cache has
more pages than the consumer cache. It iterates over the consumer cache's
pages, moves them to the source and finally moves all pages back to the
consumer. The final move is relatively cheap (though unfortunately we
still have to update all pages' vm_page::cache field), so that overall we
save iterations of the main loop with the more expensive checks.
The optimizations particularly improve the common fork()+exec*() situations.
fork() uses CoW, which is implemented by putting two new empty caches between
the to be copied area and its cache. exec*() destroys one copy of the area,
its cache and thus causes merging of the other new cache with the old cache.
Since this usually happens in a very short time, the old cache does still
contain many pages and the new cache only few. Previously the many pages were
all checked and moved individually. Now we do that for the few pages instead.
A very extreme example of this situation is the Haiku image build. jam has a
huge heap (> 200 MB) and it fork()s+exec*()s for every action to be executed.
Since during the cache merging the cache is locked, any write access to a
heap page causes jam to block until the cache merging is done. Formerly that
took so long that it killed a lot of parallelism in multi-job builds. That
could be observed particularly well when lots of small actions where executed
(like the Link, XRes, Mimeset, SetType, SetVersion combos when building
executables/libraries/add-ons). Those look dramatically better now.
The overall speed improvement for a -j8 image build on my machine is only
about 15%, though.

Intel Pro Wireless 2100 and 2200/2945 chipsets in a license correct manner.
Thank you!

* Pulled the code moving the pages out of Merge() into a separate method.

Also update the localization catalogs as needed.
CPUFrequency localization is broken : the current code works, but the DoCatalogs jamrule is not powerful enough to properly extract the catkeys.

WinDecorator:
* Now compilable
* Windows are drawing properly
* The window title is still missing for some reason

I see no other bug now, but testing welcome.
You can change the decorator using the setdecor command, but you have to add MacDecorator in /home/config/add-ons/decorators first.

-Draw the text in the titlebar
-Fix the buttons (they now are shaded like the DefaultDecorator one, that is, better than in original Mac OS)
-Draw the decorator all grey with no buttons when not focused
-Fix the border
There are some minor bugs left, but basically the decorator is now usable.
git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@34760 a95241bf-73f2-0310-859d-f6bbb57e9c96
- Style cleanup and sync with DefaultDecorator to some extent
- Don't draw a titlebar and border around menus
- Allow the client to draw something inside the window by returning the correct BRegion. (still not perfect, but it is useable, at least)

another. The code originates from vm_copy_on_write_area(). We now generate
the VM cache tracing entries, though.
* count_writable_areas() -> VMCache::CountWritableAreas()
* Added debugger command "cache_stack" which is enabled when VM cache tracing
is enabled. It prints the source caches of a given cache or area at the
time of a specified tracing entry.

-Some updates to the DecoratorManager to try to make it working. The add-on is not identified properly but I can't find out why...
git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@34749 a95241bf-73f2-0310-859d-f6bbb57e9c96
- Replaced the "userOnly" parameter by a "flags" parameter, that allows to
specify kernel and userland stack traces individually.
- x86, m68k: Don't always skip the first frame as that prevents the caller
from being able to record its own address.
* capture_tracing_stack_trace(): Replaced the "userOnly" parameter by
"kernelOnly", since one is probably always interested in the kernel stack
trace, but might not want the userland stack trace.
* Added stack trace support for VM cache kernel tracing.

access it.
* ModelLoader:
- Also add IOSchedulers to the model.
- Sort the per thread list of IORequests by start time.
- Added a bit of output in the _HandleIO*() methods when we don't know a
request or operation.

* Lock the notification service and check HasListeners(), so we don't prepare
an event message needlessly.
* The on-stack buffer for the event message was too small for I/O operation
related events. Now a larger buffer belonging to the roster object is used.
git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@34737 a95241bf-73f2-0310-859d-f6bbb57e9c96
* Added Lock()/Unlock() for explicit locking by a service user.
* Added NotifyLocked() and made Notify() inline.
* Added HasListeners() so one can check whether there is a listener at all
before preparing the event message.

This clean up the add-on from hand-made translation mess.
