vnode::covered_by fields. Together with sMountOpLock it allows write
access, either lock alone suffices for read access. Before
sMountOpLock had to be acquired for read (and write) access, which
meant that while mounting/unmounting a FS path resolution would have
to wait. In case of the UserlandFS this would even cause a deadlock
while mounting if the client tried to resolve the path of the device
to be mounted (e.g. by opening it).
* Added a clarifying comment about read access to the
fs_mount::covers_vnode/root_vnode field and removed locking in
resolve_volume_root_to_mount_point() which was not necessary for
explained reasons.

* For B_EQUALS queries the first match would be skipped.
* Exact entry name matches were broken, since the used NameIndex::Find()
expected null-terminated keys with the \0 included in the key length
while it was fed only the raw string length.

name (saves copying the name, if that has to be done anyway) and added a
wrapper version with the old interface.
* dir_vnode_to_path() was broken for file systems that didn't support
the get_vnode_name() hook. It resolved the mount point too early, so
that it was searching the mount point and not the FS root dir for the
node. It uses the get_vnode_name() function now (before resolving the
mount point).

connection to the server is lost. The former is required by our mount
command (it stat()s the mount point for some reason unknown to me). The
latter is just to be a good citizen.

* The new notification functions are used instead of send_notification()
and notify_listener() now. Mapped them in the BeOS kernel emulation
accordingly. RamFS node monitoring seems to work now.

Removed most data allocations/copying from PicturePlayer, ServerPicture now has to do this when converting coordinates.
Added additional functions to ViewLayer to copy&convert multiple BPoint, BRect, BRegion to Screen coordinates, those should be further optimized.
Removed some function call overhead.
Note: some functions of PicturePlayer don't appear to be implented by PictureDataWriter,

the code from the svn history.

happen. Flattening and unflattening BPictures now works, and
consequently, printing works too. Bug #1014 is fixed.

to B_FULL_LOCK.
* vm_clone_area() now respects the source area's wiring and inherits it. This
should fix bug #1055.
* vm_cache::type is now duplicated in vm_area::cache_type - this allows looking
it up without having to lock a vm_cache_ref; this also solves a locking bug
in vm_unmap_pages() in this regard.

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.

Unflatten()

* Renamed CenteredRect to _CenteredRect

* 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.).
