Basically, there was a pretty subtle race between the cpus in main where if the main cpu released the AP cpus and then before the AP cpus had a chance to run the boot cpu started creating the main thread (which causes smp ici messages to be created) the system would livelock, where the boot cpu waited forever for the AP cpu to acknowledge the ICI (for a TLB flush when creating the kernel stack).
Added smp_cpu_rendezvous(), used to synchronize all the cpus to a particular point, and used it a few times in main().
While i was at it i fixed another race that'll probably never happen, but what the hey. Make sure the kernel args are copied into kernel space by the main cpu before letting any other ones use it.

* Renamed CenteredRect to _CenteredRect
since is private and removed the static keyword.
* Corrected copyright dates.
Thank you!

* Made publish_vnode() available in userland. For old style FS add-ons
publish_vnode() is used when they request a new_vnode(). The semantics
of new_vnode() changed considerably in Haiku, but publish_vnode()
seems to do pretty much what the old new_vnode() did.
* The UserlandFS hosted RamFS begins to work under Haiku. It runs pretty
soon out of memory though (under vmware with 256 MB) and node
monitoring is broken ATM.

old interface is completely done in userland ATM.
It becomes more and more obvious that we probably need to provide
the kernel add-on with a bit more information about what the client FS
interface supports in the first place, so we can save unnecessary trips to
the userland. Opening/closing attributes for a FS using the old style
interface could be handled completely in the kernel add-on, for instance
(even if we lose a bit of accuracy wrt to open modes etc.).

Haiku's userlandfs. I wouldn't expect them to work very well yet, though.

need via library libuserlandfs_beos_kernel.so. Fine-tuned the legacy headers
so they can by used by the the kernel interface emulation code as well as by
the add-ons. This is actually a bit hacky, since we build everything in the
Haiku build environment and thus mix these old headers and Haiku's.

* vm_area and vm_page now have a new field "mappings" where they will store lists
of vm_page_mapping structures. vm_page::ref_count is gone, as it's no longer
needed (it was never updated correctly, anyway).
* vm_caches now have a type field, ie. CACHE_TYPE_RAM for anonymous areas - this
makes the stores a bit less independent, but is quite handy in several places.
* Added new vm_map_page() and vm_unmap_pages() functions to be used whenever you
map in or unmap pages into/from an area. They don't do much more than handling
vm_page::wired_count correctly right now, though (ie. B_LAZY_LOCK is now working
as expected as well).
* Moved the device fault handler to vm_map_physical_memory(); it was not really
used as a fault handler, anyway.
* Didn't notice Ingo's changes to the I/O space region broke lock_memory(). It
now checks the type of the area that contains the memory, and doesn't lock
anymore if not needed which solves the problem in a platform independent way.
* Implemented lock_memory() and unlock_memory() for real: they now change the
vm_page::wired_count member to identify pages that shouldn't be paged out.
* vm_area_for() now uses vm_area_lookup() internally.
* Fixed various potential overflow conditions with areas that reach 0xffffffff.
* Creating anonymous areas with B_FULL_LOCK no longer causes vm_soft_fault()
to be called, instead, the pages are allocated and mapped (via vm_map_page())
directly.
* Removed the _vm_ prefix for create_area_struct() and create_reserved_area_struct().
* Fixed a bug in vm_page_write_modified() that would not have enqueued pages that
failed to be written to the modified queue again when needed.

* Moved stuff need for the BeOS interface only into the beos_* namespace.
* Shuffled a few things around to reduce the block cache implementation
dependencies. compat.h and sysdep.c are gone accordingly.
* The whole UserlandFSServer builds now and could (at least theorectically)
drive a FS add-on implementing the old interface. The required emulation of
the BeOS kernel is not yet provided, though.

need to be adjusted.

* Shuffled functions a bit around to separate static and exported functions.
* Some other cleanup.

* Renamed them, made everything static besides vm_allocate_early() (previous
vm_alloc_from_kernel_args()) which now allows you to specify a different
virtual than physical size, and therefore makes vm_alloc_virtual_from_kernel_args()
superfluous (which isn't exported anymore, and is now called allocate_early_virtual()).
* Enabled printing a stack trace on serial output on team crash - it doesn't hurt
for now, anyway.
* Cleanup.

* Changed IconMenuItem sizing to use the same method as ModelMenuItem which
makes sure the item is large enough for the icon, and which centers the icon
in case the item is higher than the icon.
* Minor cleanup, added some comments about where those classes are used.

UserFileSystem -> FileSystem
UserVolume -> Volume
KernelUserFileSystem -> BeOSKernelFileSystem
KernelUserVolume -> BeOSKernelVolume
The BeOSKernel* classes are indeed intended to handle FS implementations
that use the (old) BeOS FS interface. We'll see how well that will work.

* Renamed a few parameters of the FS module hooks:
- *file in the attribute functions to *vnode
- v to vnode
- I could barely restrain myself from renaming the "_*" parameters. I
understand this marks return parameters, but I'd prefer a nicer prefix
or suffix (that doesn't makes you think this is a private/internal
identifier) like "out", "ret", "return", "result", or something similar.
I'd also like to propose renaming {read,write}_link() to
{read,write}_symlink(). Er, and do we need write_link() at all?

but the BDirectory was not initialized correctly. Thanks to Jonas who also provided
a patch for this (which I didn't use directly, though, for some minor reasons).
This fixes bug #1034.
