added vm_memcpy_from_physical() and vm_memcpy_physical_page(), and
added respective functions to the vm_translation_map operations. The
architecture specific implementation can now decide how to implement
them most efficiently. Added generic implementations that can be used,
though.
* Changed vm_{get,put}_physical_page(). The former no longer accepts
flags (the only flag PHYSICAL_PAGE_DONT_WAIT wasn't needed anymore).
Instead it returns an implementation-specific handle that has to be
passed to the latter. Added vm_{get,put}_physical_page_current_cpu()
and *_debug() variants, that work only for the current CPU,
respectively when in the kernel debugger. Also adjusted the
vm_translation_map operations accordingly.
* Made consequent use of the physical memory operations in the source
tree.
* Also adjusted the m68k and ppc implementations with respect to the
vm_translation_map operation changes, but they are probably broken,
nevertheless.
* For x86 the generic physical page mapper isn't used anymore. It is
suboptimal in any case. For systems with small memory it is too much
overhead, since one can just map the complete physical memory (that's
not done yet, though). For systems with large memory it counteracts
the VM strategy to reuse the least recently used pages. Since those
pages will most likely not be mapped by the page mapper anymore, it
will keep remapping chunks. This was also the reason why building
Haiku in Haiku was significantly faster with only 256 MB RAM (since
that much could be kept mapped all the time).
Now we're using a different strategy: We have small pools of virtual
page slots per CPU that are used for the physical page operations
(memset_physical(), memcpy_*_physical()) with CPU-pinned thread.
Furthermore we have four slots per translation map, which are used to
map page tables.
These changes speed up the Haiku image build in Haiku significantly. On
my Core2 Duo 2.2 GHz 2 GB machine about 40% to 20 min 40 s (KDEBUG
disabled, block cache debug disabled). Still more than factor 3 slower
than FreeBSD and Linux, though.

* Removed an inconsistency: both mouse and keyboad input device add-ons would
scan /dev/input/keyboard respectively /dev/input/mouse when loaded, but then
only monitor certain subdirectories from it. Now they monitor all.
* Made KeyboardInputDevice::InitCheck() do what the name says, ie. nothing
else.
* Now uses BObjectList instead of BList, which also simplifies the code a bit.
* Make use of the new BPathMonitor messages: as those contain a path, they
greatly simplify their handling.
* Cleanup.

* Renamed _BDeviceAddOn_ to DeviceAddOn, and put it into the BPrivate namespace.
* Moved the DeviceManager functionality into the AddOnManager - this also
solves a locking issue, as BInputServerDevice::Control() was called in the
context of the DeviceManager before.
* The AddOnManager now uses the BPathMonitor to monitor the devices that
BInputServerDevices ask for - this greatly simplifies the code.
* Got rid of TList.h, and use ObjectList.h instead.
* Added PathList class that has a list of paths with reference count, used by
DeviceAddOn and the AddOnManager.
* DeviceAddOn got an actual implementation that lives in InputServerDevice.cpp.
* Added an experimental BInputServerDevice::AddDevices() that could be used
instead of recursing over devices manually. It replaces the functionality
that was found in the DeviceManager before (this was done implicitely for
all monitored devices).
* Greatly cleaned up and simplified the AddOnManager.
* Also fixed lots of potential errors/leaks when things go wrong.
* Removed the extra locker in AddOnManager - its BLooper lock is now used
instead.
* Replaced PRINT()/PRINTERR() macros in the AddOnManager with TRACE(), and
ERROR(), both now use debug_printf().
* Hopefully this fixes the problem that I don't have keyboard under VirtualBox
from time to time.

* This means you'll no longer have to watch (and scan) directories when you're
interested in new files alone. Maybe this functionality could be used for
other cases as well, or be activated only via an additional flag.
Opinions? Stippi? :-)

fixes ticket 1522, 1591, 1946, 2318 and propably more
While creating an BBitmap in BApplication the bitmaps window looper would
be added to the applications gLooperList, thus calling Quit() on that window
and later delete on a stale window pointer in BBitmaps dtor. The Lock() check
would fix the problem, but tests on R5 have shown that BApplication hides the
offscreen window in CountWindows() and WindowAt().

was at least one character matching at the start of any file it would have
gotten a score >= 1. This rendered the substring matching completely useless
as soon as this happened, because it would always get a score < 1 depending on
the position of the occurance. Now substring matching is the first (and without
word mode, the only) score to get. Since the score depends on the position of
the match, this doesn't change anything for exact matches at the beginning, but
it does allow for substring matches even if there is a file starting with the
same letter as the search string. Also use strcasestr() instead of strstr() to
make the search case insensitive.

that solves most app_server locking headaches: it now works asynchronously,
and therefore doesn't need to lock the EventDispatcher anymore.
* EventStreams now allow to inject messages into the stream to allow the above
functionality.
* InputServerStream::GetNextEvent() no longer returns when there is no event.
* Desktop::ActivateWindow() now locks all windows before checking the
workspaces of the windows, fixing a race condition that could lead to
Window::Foremost() being called for a window that isn't on the current
workspace, leading to a crash.

report about this.

* Introduced flag "invoke_scheduler" in the per CPU structure. It is
evaluated in hardware_interrupt() (x86 only ATM).
* Introduced SMP_MSG_RESCHEDULE_IF_IDLE message, which enters the
scheduler when the CPU currently runs an idle thread.
* Don't do dprintf() "CPU x halted!" when handling a SMP_MSG_CPU_HALT
ICI message. It uses nested spinlocks and could thus potentially
deadlock itself (acquire_spinlock() processes ICI messages, so it
could already hold one of the locks). This is a pretty likely scenario
on machines with more than two CPUs, but is also possible when the
panic()ing thread holds the threads spinlock. Probably fixes#2572.
* Reworked the way the kernel debugger is entered and added a "cpu"
command that allows switching the CPU once in KDL. It is thus possible
to get a stack trace of the thread not on the panic()ing CPU.
* When a thread is added to the run queue, we do now check, if another
CPU is idle and ask it to reschedule, if it is. Before this change, the
CPU was continuing to idle until the quantum of the idle thread
expired. Speeds up the libbe.so build about 8% on my machine (haven't
tested the full Haiku image build yet).
* When spinlock debugging is enabled (DEBUG_SPINLOCKS) we also record
the spinlock acquirer on non-smp machines. Added "spinlock" debugger
command to get the info.
* Added debugger commands "ici" and "ici_message", printing info on
pending ICI message respectively on a given one.
* Process not only a single ICI message in acquire_spinlock() and other
places, but all pending ones.
* Also process ICI messages when waiting for a free one -- avoids a
potential deadlock.
* Mask out non-existing CPUs in send_multicast_ici(). panic() instead of
just returning when there's no target CPU left.

{memset,memcpy_to}_physical() functions.
Mapping lots of physical pages at once as done before was an actual
problem on systems with enough RAM, as the physical page mapper can map
only 64 chunks at a time. So multiple threads could play dining
philosophers, each getting only one of two chopsticks, waiting for
another one to be freed.

DoublyLinkedListLinkImpl, and fs_mount now uses a DoublyLinkedList instead

* The parent entry ("..") of a directory was not removed from the cache when its
directory was removed.
* When moving a directory to a new parent, it's cached parent entry wasn't
updated.
Those would lead to stale cache entries for directory parents. If a certain inode
would be reused to create a new directory after removing another, this would lead
to an invalid inode being returned when looking up the parent of the new
directory. This was easily reproducible by unzipping some directory structure,
deleting it and unzipping it again. You would end up with many "inode already
deleted" messages.

* This has the advantage that we no longer need to call get_vnode(), and
instead can use lookup_vnode().
* This means at least most of the "corrupted BFS inode" messages should be
gone; they were produced when fs_sync() tried to get already deleted vnodes.
This was actually harmless, but doesn't really help in trusting your system :-)
* Also, it no longer tries to write back removed vnodes.
* And finally, it now uses a marker vnode when iterating over the list, so
that it doesn't need to break out of the loop anymore, and can always sync
all willing vnodes.
