Added support for non-48-bit LBA, added write support.
Proper error handling still missing, write support disabled for your protection.

components - now, we divide the initialization of that service into two parts
which allows this (before, most handlers were gone after boot).
* Added debugger command that dumps the low memory handlers.
* The slab allocator now registers its low memory handler with a higher
priority, so that it'll run before the potentially heavier ones.

be checked nevertheless I guess)

deadlock whenever someone without a lock (like the page_writer()) is calling
this function.
* Added a new ReadWriteLock::TryLock() method.
* Renamed bfs_read_vnode() and bfs_release_vnode() to bfs_get_vnode() and
bfs_put_vnode() just like those functions are called in fs_interface.h.
* Fixed a warning in BPlusTree::_SplitNode().

the BeBook mentions it does
* make sure the view is invalidated on resize
* needs more fixes (for example GetPreferredSize() does not take everything
into account)

doesn't exist, so I just used a BFile instead... this should fix part of
ticket #1423, if someone wants to look into the gateway retrieval
(settings.cpp) to fix the other half of the bug, that would be great

anything, if a line is available. Fixes bug #1483.
* Replaced the request owner waiting semaphore by a condition variable
and removed the now no longer needed SemaphorePool.

Apparently not everyone checks the page state for PAGE_STATE_BUSY.
vm_page_write_modified_pages() does now at least.
* Fixed typos in comments.

* We now have a page writer that takes some pages from the modified queue
and writes it back every few seconds. It can be triggered by the page
scanner to do that more often, though. That mechanism can be greatly
improved once we have our I/O scheduler working.
* Removed vm_page_write_modified_page() again - it was all "eaten up" by
the page writer.
* Reworked vm_page_write_modified_pages() a bit: it now uses
vm_test_map_modification() and vm_clear_map_flags() instead of the
iterating over all areas which wouldn't even work correctly.
The code is much simpler now, too.
* You usually put something to the tail of a queue, and remove the contents
from the head, not vice versa - changed queue implementation to reflect this.
* Additionally, there is now a enqueue_page_to_head() if you actually want the
opposite.
* vm_page_requeue() allows you to move a page in a queue to the head or tail.
* Replaced vm_clear_map_activation() with vm_clear_map_flags() which allows
you to clear other flags than PAGE_ACCESSED.
* The page scanner dumps now some arguments with each run.
* Removed the old disabled pageout_daemon() from NewOS.

* Clear fMinMaxValid when a new constraint is added. "Height for width"
constraints are therefore no longer ignored.

be considered redundant, although they weren't. We do now use smaller
"unlimited" sizes which we can add without risking overflow, and can thus
correctly identify redundant constraints. This fixes the
SplitterGridLayoutTest1 in the LayoutTest1 app.

being leaked.

made it conditional, added/modified comments documenting the maths and
algorithms.
* Refactored quite a bit in ComplexLayouter and added special handling for
the case that the desired solution is already feasible.

* This should fix the broken build from earlier - thanks Stefano for the note!
* That also allowed to clean some other includes a bit.

to the private VM types are including vm_types.h now.
* Removed vm_page, vm_area, vm_cache, and vm_address_space typedefs; it's
cleaner this way, and the actual types are only used in C++ files now,
anyway.
* And that caused changes in many files...
* Made commpage.h self-containing.
* Minor cleanup.
