introduces the following relevant changes:
* VMCache:
- Renamed vm_cache to VMCache, merged it with vm_store and made it a
C++ class with virtual methods (replacing the store operations).
Turned the different store implementations into subclasses.
- Introduced MergeStore() callback, changed semantics of Commit().
- Changed locking and referencing semantics. A reference can only be
acquired/released with the cache locked. An unreferenced cache is
deleted and a mergeable cache merged when it is unlocked. This
removes the "busy" state of a cache and simplifies the page fault
code.
* Added VMAnonymousCache, which will implement swap support (work by
Zhao Shuai). It is not integrated and used yet, though.
* Enabled the mutex/recursive lock holder asserts.
* Fixed DoublyLinkedList::Swap().
* Generalized the low memory handler to a low resource handler. And made
semaphores and reserved memory handled resources. Made
vm_try_resource_memory() optionally wait (with timeout), and used that
feature to reserve memory for areas.

* move libprint headers into libs headers folder accordingly
* merge all shared folders sources into kits print, we might build later on a
real print kit, propably also to access cups from an nicely API, atm static
* move all shared headers into private print, also pr_server.h from interface
* adjust build to work with the changed folder layout

really work yet (there are some bits missing in the IORequest and IOScheduler
to able to use them this way).

* Fixed crash when it couldn't find the device.
* Added a "-l|--list-types" option that list all file systems that support
initializing (currently only BFS).
* Added a "-q|--dont-ask" option that prevents mkfs from questioning your
command :-)
* Fixed return value - would return failure to the shell when it actually
succeeded and vice versa.
* Improved/clarified some output and fixed spelling errors.
* Errors now have the command name as prefix, as that's how it is usually
done (and very useful for batch processing).
* Cleanup, though I kept the FsCreator class which is kinda superfluous.

did not set the "devicesOnly" flag to false when calling RegisterDevice().
* ddm_userland_interface.cpp incorrectly wrote to userland memory when it
assigned "neededSize" in several places.
* Replaced on-stack path with the UserStringParameter class where appropriate.
* Made the UserStringParameter class castable to char*.
* Minor cleanup in KDiskDeviceManager.cpp.

various different menu situations and there seem to be no negative side
effects.

* Moved data buffer creation to a TestSuiteContext class.
* Added checks if the I/O operation does the correct thing, ie. reads/writes
the data to the right offset.
* Rearranged DMA translation: we now handle the partial write case correctly
(bounce buffer must always span over the whole block), and are able to join
adjacent bounce buffers together.
* The new _AddBounceBuffer() method also respects boundary and segment size
restrictions for bounce buffers.
* IOOperation now prepares the outgoing vecs/offset/length to contain the
right data for the current phase (partial read begin/end/do-all); it will
also make sure that the lengths of the vecs are of the same size than the
whole request.
* All tests are now passed, the I/O request implementation seems to be ready
for integration now.

Hide USB errors better from the upper layers: Only try the "clear feature"
command if the error is B_DEV_STALLED. On other errors, the clear feature
was likely to fail, as it should only be used on stalled devices. Errors
intended to be ignored were thus not ignored because of the "clear feature"
failure.

behind highspeed hubs with multiple transaction translators not to work.
* The parent hub isn't necessarily the one providing the transaction translator
for a full- or lowspeed device. Therefore we need to inherit the hub/port
addresses to lower devices unless we are a highspeed hub that might be the
actual provider of the transaction translator. This logic error caused full-
and lowspeed devices not to work if they were behind a fullspeed hub that
itself was behind a highspeed hub.
This fixes bugs #1889 and #2501.

automounter already mounted these partitions. Since this happens asynchronously,
it sometimes worked and sometimes not. The very simply and non-hacky fix for this
problem is to send a message from the automounter to the application looper to
have it open the previous windows after the initial mount scan is done.

* Fixed mounting previously mounted partitions. fSettings was never initialized when restoring
the settings. The code I removed earlier didn't do that either.

from the settings message just after having restored it. This should fix
restoring the previously mounted partitions, but I have not tested it yet.

It works by adjusting the display_mode to have twice the virtual height to
cause the graphics driver to allocate enough frame buffer. Since hardware
acceleration calls are based on geometry locations instead of memory locations,
accelerated calls can work in the offscreen buffer with this method.
Similarily, the new CopyBackToFront() method copies the back buffer into the
front buffer with hardware acceleration. The code is currently disabled, since
not all graphics drivers handle the virtual versus display size correctly,
for example the intel_extreme driver. It works for example with the radeon
driver, but another problem prevents me to judge the benefit of this method.
Most types of screen redraws are flicker free, though, which is the whole point
of the excercise. :-)
Another problem with the current code is the initial mode switch. It does
not try again to double the frame buffer in the fall back code paths. It could
also check the frame buffer memory at all, before even trying to save some
cycles.
To see it in action, uncomment the code at line 508.

* Added a flag "fIsOffscreenBuffer", which is used to shift the frame buffer
pointer to the position after the visible frame buffer.

* Minor coding style changes.

parameters. This caused ticket #1732 for me. At another place in the code,
the native resolution is added to the supported mode list and there it is
hardcoded to the first flatpanel info.

Either of the two should work when the native resolution is 1368x768.

- disable tracing mmu
- make scratch buffer 8k as it's declared as such... that makes things much better indeed :)

* Fixed build: round_up() has been renamed to key_align().
* Whitespace cleanup.

* Fixed a bug that could easily corrupt your disks (yeah, one of those
again): bfs_get_file_map() truncated the last vec incorrectly and
would potentially return a too large file size -- which was later
happily overwritten with file data, but could have belonged to
anything but that file (like inodes, B+trees, etc.).
* Renamed previous round_up() function to key_align().
* Added round_up() template function, and used it where appropriate.
* The latter actually fixed two bugs where the and mask was computed in
32 bit where it should have been in 64 bit.
* Inode::FindBlockRun() should have checked the max indirect size
instead of the direct size - this didn't cause any problems, though.
* White space cleanup.

- bitfield definitions of page dirs were reversed... 040 is still wrong though.

- move part of mmu handling to mmu-dependant files and extend ops
- implemented 040 mmu init. doing so I spotted a bug in ARAnyM which ignored [ID]TT0. Linux likely doesn't use them but I was too lazy touse temporary page tables. I also noticed bitfields were in wrong order, to be fixed.

'-b' option).

* FileMap::_InvalidateAfter():
- Off-by-one error. The last extend (which normally should be kept)
was thrown away, too, but still accessed afterwards. Worst case
could be a write to free()d memory.
- Drop the last extend when it would be truncated to zero size.
* FileMap::Translate():
- Incorrect handling of B_BUFFER_OVERFLOW case in the
vfs_get_file_map() loop. After the loop the function would return
incorrectly, making the caller think all vectors in the provided
array had been initialized correctly. This could cause a file system
implementation using the file map to read from or write to random
disk locations, in the latter case possibly corrupting the file
system.
- Some readability improvements in the final loop. Removed incorrect
check.

it can actually be used (that should have been part of an earlier commit,
but didn't break the build this time).
* dump_modules() must use kprintf() instead of dprintf().
