it was done in SAS/C... (yeah, that was ages ago). This fixes bug #2030.
* Also, we should probably check if the area we're about to shrink/remove
actually is a reserved area.

to manage this, avoid locking the main sLock in notification handling methods. Instead fill up two lists which will be emptied later by the kernel daemon thread.

* Simplified setting B_OP_COPY drawing mode.
* PopState() at the end of drawing, not before.

put_vnode() might be removed from our map, if that was the last reference to
the node, so _DecrementVNodeCount() would emit an error message -- harmless
but annoying. :-)

something comes in -- this could be greatly improved, though.
* Cleanup.

device additions/removals can be monitored.
* Minor cleanup.

kernel implementation ignores, so we should allow that in userland, too.

too. It's slightly adjusted to use the thread blocking syscalls and a benaphore
style threads spinlock replacement. This solves the following problems:
* The static mutex/rwlock initializers are safe now.
* The rwlock implementation is compatible with the kernel implementation. E.g.
a write lock owner can acquire a read lock, which would dead-lock before.
* We don't use semaphores anymore. With a userland BFS one could quite easily
hit the global semaphore limit before.

makes them more convenient to use, since the caller doesn't need to know the
target threads' user thread structure.
* Adjusted the pthread rwlock implementation accordingly.

the free list. Do that with the threads lock held. This allows other threads
to freely access a thread's user thread structure while holding the threads
lock.

* Increment the vnode reference count in NewVNode().
* Introduced a VNode::published flag that allows PublishVNode() (a) to discard
the node on error and (b) not to increment the node's reference count in case
the node had been created by NewVNode() before.
* Added missing fVNodeCountingEnabled check in _RemoveInvalidVNode().
* _PutAllPendingVNodes():
- nodeFound was never reset, so it would loop forever, if there was at
least one node that needed to be put.
- VNode::useCount needs to be set to 0 explicitely. Since vnode reference
count tracking is already disabled PutVNode() doesn't decrement it and
thus we would loop forever, respectively cause the VFS to panic() first.
- If the node has not been published, we need to publish it before putting
it, since otherwise the VFS would complain that the node is busy.

* Automatic whitespace cleanup.

We do some caching using a hash table indexed by the operations vector.
* Pass the vnode capabilities to the kernel module.
* In the kernel tailor the operation vectors for volumes and vnodes passed to
the VFS according to the respective capabilities. This way those vectors look
pretty much like those from the client FS. This saves unnecessary calls when
hooks are not implemented and should also fix compatibility problems in cases
where not implementing a hook and returning an error don't mean the same to
the VFS.
* Inlined some of the kernel module Volume class getters.

FileCacheWriteRequest. Stacking requests is now possible, so reentering the
file system while serving those requests is no problem anymore. BFS seems to
be quite happy as far as I've tested it.

- Send() now also gets the message to send as parameter.
- Added methods to reserve and unreserve space in the buffer.
* RequestAllocator: Uses the port buffer reservation methods now. This allows
to let more than one RequestAllocator use a Port in a stack-like manner.
git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@29565 a95241bf-73f2-0310-859d-f6bbb57e9c96
* Change Port::Receive() semantics. It does no longer use the buffer associated
with the object. Instead it allocates heap memory for the caller. Since
there's only one caller who clones the message anyway, we save one copy this
way (though we have an additional syscall in userland) and don't overwrite
a request being prepared for sending.
* Changed RequestAllocator::ReadRequest() to also read the request from the
port.

* The loop is unnecessary, since the call doesn't block anyway, so it can't
be interrupted.
* Set the holder, if KDEBUG is enabled. Otherwise the panic() in
recursive_lock_unlock() would be triggered.
