added an IORequest::Init() version with that parameter. This makes
splitting an iovec array into IOBuffers/IORequests easier.
* Added IORequest::CreateSubRequest(). It creates and adds an IORequest
that covers a part of the range of the parent request, but may use
another file offset. This will be used e.g. in the way that the parent
request describes an I/O operation for a file while its subrequests
describe the same operation translated to the underlying device.
* Added IORequest::DeleteSubRequests(), which does the obvious. It's
also invoked in the destructor.
* Added method for iterating through subrequests.
* Made IORequestChunk::{Set,Reset}Status() protected. For both
subclasses some locking is needed (though different locking), so we
rather make this more explicit.
* Added IORequest::SetStatusAndNotify(), which is SetStatus() +
NotifyFinished() with proper locking.
* Changed the I/O request finished and iteration callback signatures.
The finished callback has got an additional "status" argument, since
the request itself may already be inaccessible at the time the
callback is executed.
* Changed IORequest::NotifyFinished(). The policy is now that if the
iteration callback fails, the method will do the finished
notifications. This simplifies things in the iteration callbacks.
* Fixed bug in IORequest::_CopyPhysical(): It didn't take into account
that the physical buffer could not be page aligned.

B_OP_COPY which is about 2.4 times faster than the AGG version (but of
course less generic). The speed up is even better for smaller and even
scales.

an invalid page state was supplied. The comment was misleading too,
as the pages weren't reserved upfront.

* When drawing BBitmaps with scaling in the app_server, use a bilinear
filter when a bitmap has this flag set. (Hope nobody objects, otherwise
I can revert or improve this. Performance can certainly be improved, since
the AGG implementation is too generic. But that goes for the nearest
neighbor implementation as well.)
* Flags are uint32, fix app_server side code to declare them correctly. Use
appropriate link methods in BBitmap and ServerApp.
* Enable the BeOS compatibility mode for B_RGB32 (works just like B_RGBA32
in B_OP_ALPHA mode).

children of the device and recreate them so that they are updated to any
changes. MainWindow::_Initialize() was using a stale BPartition pointer
after calling CommitModifications(). Now the pointer is recreated from the
id. Should fix#2548. Untested.

* Renamed sModifiedTemporaryPages to sModifiedNoSwapPages to better
express what this variable is about.
* Changed tracking of sModifiedNoSwapPages. It really counts
non-swappable pages only, now (if swap support is enabled).

- Enabling all net_buffers code & ACL
- Asume contiguusness for outgoing packets
- Fix incorrect cleaning of btDevices
- Posting ACL data to the net_device Kernel module.
Sumarizing this enables ACL tranmision mode in the driver which starts to be "real network data" of the bt protocols not configuration as we had before

buffer lives in userland can easily be checked via IS_USER_ADDRESS.
* Added B_VIP_IO_REQUEST flag which will be used by the page writer and
should cause allocations to be made in a way that they cannot fail.
Not implemented yet, though.

* Split IORequest::ChunkFinished() into OperationFinished() and
and SubrequestFinished(). Moved the notification part into a new
method NotifyFinished().
* Added new IOScheduler thread for notifying finished requests.
IOScheduler::_Finisher() hands over finished request to it, unless the
requests don't have callbacks. We need the separate thread, since the
callbacks can potentially reenter the scheduler and thus cause
deadlocks.

versions of the AddressSpaceReadLocker constructor and SetTo(). When
true it will get a new reference to the address space.
* Changed vm_soft_fault(): Now it gets the address space as a
parameter (for page faults getting it happens in vm_page_fault()).
This should fix lock_memory_etc() for other teams -- it used the
correct address space before, but the invoked vm_soft_fault() always
used the current team's address space.

* Init swap support in main().
* Added "bool swappable" parameter to
VMCacheFactory::CreateAnonymousCache(). A cache supporting swapping
is created when true. Adjusted invocations accordingly.
* The page writer does now write non-locked swappable pages (when
memory is low).
* Fixed header guard of VMAnonymousNoSwapCache.h.
* Swap support is compiled conditionally, controlled by the
ENABLE_SWAP_SUPPORT in src/system/kernel/vm/VMAnonymousCache.h. It is
disabled ATM. Since no swap files are added, it wouldn't have much
effect anyway.

(which requires the later initialized VFS).
